- [Fractal image coding](https://atastypixel.com/fractal-image-coding/) - I'm studying for a Digital Video Coding and Compression exam, and just wanted to share the coolness that is fractal coding. Fractals are geometric objects which are said to have infinite complexity, and are often self-similar (that is, a small portion of the fractal is the same as the whole fractal). Iterated Function Systems (IFS)
- [URLs, the last great 'what the'](https://atastypixel.com/urls-the-last-great-what-the/) - Happily surfing the Microsoft website today (don't ask), I was amused to note the ridiculous URLs in use - Here are some examples: http://www.microsoft.com/ downloads/details.aspx? FamilyId=4C254E3F-79D5-4012- 8793-D2D180A42DFA &displaylang=enhttp://www.microsoft.com/ downloads/Browse.aspx? displaylang=en&productID= 4289AE77-4CBA-4A75- 86F3-9FF96F68E491http://www.microsoft.com/ downloads/info.aspx?na=63&p=& SrcDisplayLang=en& SrcCategoryId=&SrcFamilyId= 9996B314-0364-4623-9EDE- 0B5FBB133652&u=%2f genuine%2fdownloads%2f WhyValidate.aspx%3ffamilyid %3d9996B314-0364-4623- 9EDE-0B5FBB133652 %26displaylang%3den Whatever happened to friendly URLs? If I was going to point someone to
- [Idiot-proof 'rm'](https://atastypixel.com/idiot-proof-rm/) - After my unfortunate accident, I decided to spend a moment trying to make sure it doesn't happen again. Thus, the (semi) idiot-proof 'rm' was born: This is a small script that replaces 'rm'. Instead of deleting, it moves the files in question to ~/.Trash. It'll create a directory structure under ~/.Trash that echoes that of
- [A brief shell scripting tutorial](https://atastypixel.com/a-brief-shell-scripting-tutorial/) - Shell scripts are very useful things, whether they're prepared and saved to a file for regular execution (for example, with a scheduler like cron), or just entered straight into the command line. They can perform tasks in seconds that may take days of repetitive work, like, say, resizing or touching up images, replacing text in
- [Unix tools tutorial](https://atastypixel.com/unix-tools-tutorial/) - Last week we took a quick look at shell scripting. This week we'll finish off with a look at some useful tools - awk, sed, sort and uniq. These are used mainly for manipulating text, and gathering information. Awk and sed provide a fairly rich language set, but can be used for very simple things
- [Are you leaking search queries?](https://atastypixel.com/are-you-leaking-search-queries/) - Recently, AOL leaked 20 million search queries to the world (as covered in a NY Times article). It listed search queries alongside user numbers, which links search terms to individuals. Although no names are listed, it is often not difficult to determine (or at least narrow down) an individual's identity, given their search history, as
- [Incremental rsync backups](https://atastypixel.com/incremental-rsync-backups/) - I've written a shell script to do incremental backups with rsync (inspired by this macosxhints article). The script takes one or more sources, and a local destination path, and creates an incremental rsync mirror at the destination. It will first create an initial archive, then will subsequently create a new archive, hard-link the last archive
- [One-way blogs are irritating; E-paper disposability](https://atastypixel.com/one-way-blogs-are-irritating-e-paper-disposability/) - I'm annoyed by blogs that don't allow people to post comments! One of the exciting elements of the blogosphere is the two-way nature of it, and the ability to create global discussions anywhere, on any topic, where anyone at all can comment. It's exciting because it's democratic and egalitarian, the way the Internet should be!
- [Suck those clicking earplugs](https://atastypixel.com/suck-those-clicking-earplugs/) - I've been having trouble with my left iPod earplug, which has been clicking and distorting beyond a (relatively low) volume - making listening very annoying. I was making plans today to go and visit the Apple store where I bought the iPod, when I remembered reading something about sucking on the troublesome earplug. I gave
- [Mail's 'Entire Message' search gives '0 found'](https://atastypixel.com/mails-entire-message-search-gives-0-found/) - Mail just stopped returning search results when I did a full text email search. I did a bit of googling and found some discussion on the problem with 10.4.7 that was fixed with 10.4.8. So, not that. Someone in that thread mentioned that they forced a re-index of their entire drive in Spotlight. Scott, another
- [DVD-R media guide](https://atastypixel.com/dvd-r-media-guide/) - I've been using some 'mag media' blank DVDs I bought at JB HIFI, and they've given me a bit of grief. I've had a number of failed burns, and in one instance, my DivX player wouldn't read a disc that had been burned a couple of weeks earlier. I'm almost out of blanks, so I
- [OS X performance tweak?](https://atastypixel.com/os-x-performance-tweak/) - While looking around for information on some fairly irritating memory leaks I've been encountering in OS X (some common library seems to be chewing up memory, so that after a few days of running, all my apps take up enormous amounts of memory), I found this old tip regarding setting the maxvnodes parameter. A comment
- [Run-down on Mac OS X media center software](https://atastypixel.com/run-down-on-mac-os-x-media-center-software/) - Update: Matt Hansson has written a more up-to-date overview of the offerings. His findings: He still prefers Mediaportal on Windows to the currently available Mac solutions. Damn. We've recently set up a home entertainment centre, consisting of a 40" Samsung LCD TV, a Yamaha 6.1 audio setup and a Mac Mini. In order to drive
- [Automatic iTunes track rating based on listening patterns](https://atastypixel.com/automatic-itunes-track-rating-based-on-listening-patterns/) - I have written an application that analyses listening patterns in iTunes and generates track ratings automatically. This is particularly useful when using Party Shuffle. The application awards a high score to tracks that are listened to frequently, and penalises tracks that are skipped frequently. It uses the formula: rating = (100 * ( (play frequency
- [AutoRate 1.4.2](https://atastypixel.com/autorate-142/) - Edit: Please see the official AutoRate product page for the latest version Hot on the heels of 1.4.1, AutoRate 1.4.2 has just been released. It has a drawer instead of a separate preference pane, and the playlist selection has moved down there. In addition, I've again tweaked the ratings - as there's now a setting
- [Creating applications in XCode using frameworks](https://atastypixel.com/creating-applications-in-xcode-using-frameworks/) - Defining a proper, logical structure to a new project is an important early step. It will save time later, when you realise you really need to enforce a bit of order, and will make development easier over the life span of the project. One useful structure that can be fairly well managed in XCode makes
- [Wider implications for popups!](https://atastypixel.com/wider-implications-for-popups/) - There's a story on Arstechnia about a substitute teacher who was nearly imprisoned for 40 years for allegedly showing porn to students, after an event that can only be explained by a fairly standard popup attack on an unprotected classroom computer: She went to the bathroom, and returned to find students clustered around the attacked
- [AutoRate 1.4.1](https://atastypixel.com/autorate-141/) - Edit: Please see the official AutoRate product page for the latest version I've released version 1.4.1 of AutoRate, which now has the option to use just play counts to generate ratings, or a variable mixture of play counts and play frequencies. As the use of play frequencies tends to bias towards new tracks (which have a high
- [MacBook Pro (first ed) refusing to eject CD](https://atastypixel.com/macbook-pro-first-ed-refusing-to-eject-cd/) - I have a first edition MacBook Pro (asking for trouble), and I just had an interesting run-in with the optical drive. I put in an old burned CD with a paper label (stuck all the way down, mind you - no bits sticking out), and it was making some very odd noises, although it was
- [AutoRate in Objective-C](https://atastypixel.com/autorate-in-objective-c/) - I'm currently re-doing AutoRate in Objective-C. I've heard from a few users with very large libraries (20,000+) that the current version takes several hours to go through their entire library. Should be able to do much better than that in Obj-C instead of AppleScript. Should give me more scope to do some other things as
- [Multiple email aliases in Mail](https://atastypixel.com/multiple-email-aliases-in-mail/) - I've always wanted to be able to send email from several different addresses - for official university stuff, I want to send from my Monash address; for personal mail, from my personal address. For Tzi Software-related stuff, from my Tzi Software address. Until now, I thought one had to create a separate account for every
- [Inserting vector graphics in Office documents](https://atastypixel.com/inserting-vector-graphics-in-office-documents/) - Sometimes I have the misfortune of having to write conference papers in Microsoft Word, instead of a more civilised environment like LaTeX. Usefully, Word will refuse to import any kind of vector image format except for their own proprietary and crippled format, WMF/EMF. So, when it comes to diagrams, most people tend to throw their
- [Serendipity (S9Y) importer for Wordpress](https://atastypixel.com/serendipity-s9y-importer-for-wordpress/) - Import posts, comments, tags, categories, authors from Serendipity (S9Y) into Wordpress. This is a refined version of Technosailor's importer.
- [Optimising performance for OS X](https://atastypixel.com/optimising-performance-for-os-x/) - A seemingly unavoidable trait of all operating systems is the notorious slow-down - it doesn't seem to matter how nicely you treat the system, after a few months it'll start grinding to a halt (or is it just me?). This has happened to me in Windows, Linux and OS X, and it drives me absolutely
- [Using Quicksilver with iTunes](https://atastypixel.com/using-quicksilver-with-itunes/) - I tend to play a fair bit of music while I'm working; sometimes I want to hear something in particular, and sometimes I'm happy to just let the shuffle do it's thing (although some tracks I'll skip). Quicksilver makes all this really easy when used in combination with iTunes' Party Shuffle. Firstly, I have the
- [Connecting an iMac up to your TV](https://atastypixel.com/connecting-an-imac-up-to-your-tv/) - Update: Please note, this technique is the 'lowest common denominator' option, which will give the least quality image, but will probably work with any TV. If your TV supports it, the best options are VGA (the easiest option, and what I use with my 42" Samsung TV and my Mac Mini), HDMI, or component. I
- [Inquisitor still works on OS X 10.5 Leopard!](https://atastypixel.com/inquisitor-still-works-on-os-x-105-leopard/) - I read reports that Inquisitor was broken on Leopard because the InputManagers system has changed/been disabled. Not so! Just create /Library/InputManagers and move ~/Library/InputManagers/Inquisitor into there, then chown -R root:admin /Library/InputManagers. Restart Safari, and it's back!
- [AutoRate in Japan's Mac Fan Magazine](https://atastypixel.com/autorate-in-japans-mac-fan-magazine/) - AutoRate got a mention in the Japanese Mac Fan magazine! Anyone speak Japanese? < p style="text-align:center">
- [My iTunes iPhone playlist setup](https://atastypixel.com/my-itunes-iphone-playlist-setup/) - I used to manually choose the tracks to sync to my iPod Nano, but now I have 7-something gig to play with on the iPhone, it's a bit too much. Instead, I use smart playlists to select which tracks to carry with me. Two standard playlists, 'iPhone Selections' and 'iPhone Exclusions' allow me to specifically
- [Intelligent image resize](https://atastypixel.com/intelligent-image-resize/) - There are times when you need a certain resolution in an image (like if you want to use it as a desktop wallpaper), but all you have is a small version - which means if you try and enlarge it, you get either a blurred or pixellated version. There's actually another way, which doesn't seem
- [TVSync syncs your TV episodes with iTunes and your iPod or iPhone](https://atastypixel.com/tvsync-syncs-your-tv-episodes-with-itunes-and-your-ipod-or-iphone/) - I've just created a glorified bash script that will intelligently (hopefully) synchronise downloaded or recorded episodes from TV shows with an iTunes library. From the website: This utility will automatically transfer video files of TV series (such as those downloaded from Bittorrent or recorded from TV) into iTunes for transfer onto an iPod/iPhone. It can
- [PHP debugging](https://atastypixel.com/php-debugging/) - Managing PHP debugging can be tricky as, by default, errors and test 'echo' statements can be lost along with all the other output. This problem is compounded when using AJAX, and errors can turn up in XML streams, causing all sorts of problems. A better solution is to redirect all of that output into an
- [Memory tricks: Linking it in](https://atastypixel.com/memory-tricks-linking-it-in/) - I tend to have an appalling memory for performing tasks, unaided by beeping alarms - I get lost in the moment and it just goes out of my head. A trick I found many years ago works surprisingly well, though, when I actually remember to use it (of course, that's the real trick). Memory recall
- [Automatically eject all disks on sleep, reconnect on wake](https://atastypixel.com/automatically-eject-all-disks-on-sleep-reconnect-on-wake/) - Using a laptop with permanent external drives can be a bit annoying when you leave the desk - you have to manually eject all your devices, otherwise you get that dreaded 'Device Removal' dialog. With a little bit of Terminal magic, you can automatically eject disks when you sleep the laptop, meaning you can just
- [Automatic genre identification and 'similar track' matching](https://atastypixel.com/automatic-genre-identification-and-similar-track-matching/) - I've got a bit of new music lately, and I've noticed that the genre is always a bit off. Genre is a pretty tricky thing to figure out for most modern music, as there's so much 'cross-pollination' going on in the music world. Additionally, over a single album, several genres may be visited (eg. folk,
- [Nasty long sleep times with SleepWatcher](https://atastypixel.com/nasty-long-sleep-times-with-sleepwatcher/) - If you followed my prior hint on automatically ejecting volumes on sleep (@ macosxhints), I've just discovered that SleepWatcher adds about 30 seconds to the time taken to sleep. This has been a big frustration to me over the last month or so, and now I know why. I'm removing the utility - I'd rather
- [Convert text to iTunes audio book](https://atastypixel.com/convert-text-to-itunes-audio-book/) - After reading a hint on macosxhints on how to create an audio file from text, because I wanted to keep reading my book while I was driving, and figured that holding the book in front of me probably wasn't the best option, I figured the process could probably be streamlined a bit. So, I've made

- [Easy inclusion of OpenSSL into iOS projects](https://atastypixel.com/easy-inclusion-of-openssl-into-iphone-app-projects/) - Oddly, iOS doesn't provide any OpenSSL implementation at all -- If you want to do anything with crypto (like checking signatures, checksumming, etc.), you have to build in the library yourself. I came across a great XCode project wrapper for OpenSSL yesterday, by Stephen Lombardo. This is an XCode project file that contains a target

- [Pushing MultiChannelMixer to the limit](https://atastypixel.com/pushing-multichannelmixer-to-the-limit/) - A friend made an interesting suggestion to an issue I'm facing in the upcoming Loopy 2, and I thought I'd do some investigation: How many tracks can the MultiChannelMixer (kAudioUnitSubType_MultiChannelMixer) manage at once? He was quite optimistic, and as it turns out, he was right: It's rather capable. I modified the iPhoneMultichannelMixerTest sample project to

- [A quick-and-dirty audio sample mixing technique to avoid clipping](https://atastypixel.com/how-to-mix-audio-samples-properly-on-ios/) - In the real world, when you hear two sounds at once, what you're hearing is the combination (in the "+" sense) of the two noises. If you put five hundred drummers in the same room and, avoiding the obvious drummer jokes for now, told them all to play, you'd get drummer 1 + drummer 2
- [This made my day: An App Store review](https://atastypixel.com/this-made-my-day-an-app-store-review/) - App Store reviews often seem to be an odd mix of bile and vitriol, misplaced support requests, and glowing praise, making my routine App Store review-sweep somewhat of a rollercoaster! This time around, though, this review of The Cartographer made my day (this is the kind of person I write apps for!), and I had
- [Resuming ADC downloads ('cos Safari sucks)](https://atastypixel.com/resuming-adc-downloads-cos-safari-sucks/) - So, Safari's resume facility is just awful -- it'll randomly restart downloads from the beginning, clobbering anything that's already been downloaded, and the resume button will frequently disappear entirely and mysteriously from the downloads window. And if the session has expired, it'll cause all kinds of havoc. Anyone downloading the gazillion-gb iOS/Mac SDK + XCode

It lives at some obscure folder within /Developer - use find to dig it up and symlink it into /usr/local/bin if you wanna use it conveniently from the command line. Anyway, after

For me, as I've discovered, it's striving to create beautiful and functional user interfaces, or constructing in code the perfect representation of a workflow. It's creating a piece of software that works like an extension of yourself,

Loops are automatically time-fitted for perfect synchronisation, using the frankly awesome Dirac audio processing library.
- [Objective-C + Cocoa on the Command Line](https://atastypixel.com/objective-c-cocoa-on-the-command-line/) - Sometimes there's just one tiny snippet of Cocoa code that you want to test -- maybe to find out the output of NSDateFormatter for various cases, testing out some text replacement routine, or testing out some image drawing code. It's often too much trouble to create a new XCode project and set up the framework

- [A simple, fast circular buffer implementation for audio processing](https://atastypixel.com/a-simple-fast-circular-buffer-implementation-for-audio-processing/) - Circular buffers are pretty much what they sound like - arrays that wrap around. They're fantastically useful as scratch space for audio processing, and generally passing audio around efficiently. They're designed for FIFO (first-in-first-out) use, like storing audio coming in the microphone for later playback or processing. Consider a naive alternative: You copy the incoming
- [Easy AAC compressed audio conversion on iOS](https://atastypixel.com/easy-aac-compressed-audio-conversion-on-ios/) - From the iPhone 3Gs up, it's possible to encode compressed AAC audio from PCM audio data. That means great things for apps that deal with audio sharing and transmission, as the audio can be sent in compressed form, rather than sending huge PCM audio files over the network. Apple's produced some sample code (iPhoneExtAudioFileConvertTest), which

There are two command-line utilities, pbcopy and pbpaste that provide direct access to the OS X clipboard. They're quite useful for doing various quick things with clipboard contents, like, say, writing it to a file: pbpaste > Desktop/output.txt Or altering them: pbpaste | sed s/bacon/bea-con/g | pbcopy

By default, the "Tweet" button that AddThis provides will append "via @AddThis" to the end of tweets, which seems to me a little uncool, given that it's your content. So, here's a little plugin that lets you

So, I create two different views within the nib, one portrait, one landscape, each with the same view hierarchy, but with a different layout. When

It's great, but -- and it's a kinda large but -- the OS X driver (it's an RTL8187) is just mind-blowingly appalling. It crashes very frequently,

- [Searching iOS header files with Xcode](https://atastypixel.com/searching-ios-header-files-with-xcode/) - I'm often having to grep through various iOS frameworks in search of error codes that appear ("What the bloody hell does -10867 mean?"). This can be a bit annoying - especially while working with Core Audio - so I put together an Alfred workflow that does it for me. Here it is - type "hs"

- [Want to be able to downgrade your apps? Save 'em before updating.](https://atastypixel.com/want-to-be-able-to-downgrade-your-apps-save-em-before-updating/) - Regrettably, the App Store doesn't really make it easy to downgrade apps if an update goes awry. This can be pretty problematic if you use your apps for critical stuff like live music and it all goes horribly wrong the day before a gig. That problem's pretty easy to solve though. Just back up your
- [Help! iOS 7 broke my microphone input!](https://atastypixel.com/help-ios-7-broke-my-microphone-input/) - We hear a lot about people having problems with their music apps on iOS 7 no longer receiving audio. I thought it was time I posted an article describing why this is happening, and how to fix it. iOS 7 introduced a bunch of new security and privacy features and restrictions. In particular, when an

I'm completing this article now, on the day we say an emotional farewell to our motorhome Nettle, who has today been sold to a new family in the UK. It seems like a fitting time to tie off some loose ends as we
- [](https://atastypixel.com/errands/) - So many things to do! Life as an indie developer can be a bit chaotic sometimes, and the last two weeks have been no exception - I’ve been busy with some urgent-ish tasks, which have taken time away from Masterpiece development. Let me tell you them.
- [](https://atastypixel.com/nothing-to-see-here/) - No video this week, folks: I’ve decided to take a week or two to sort out a long-overdue Loopy update. It’s gonna sort out a few issues, include the improved clock sync stuff from the new Spectacular Sync Engine, and one or two other new things.
- [](https://atastypixel.com/midi-clock-receiving/) - I’m still working on The Spectacular Sync Engine this week, and talking about what’s involved in making a stable MIDI clock receiver. Hopefully it’s not all gibberish (I don’t even see the code - just blonde, brunette…). Developers, if you want to stay informed about The Spectacular Sync Engine: http://thespectacularsyncengine.com
- [](https://atastypixel.com/thespectacularsyncengine/) - I’m on a bit of a tangent this week, developing an open source MIDI clock implementation. http://thespectacularsyncengine.com
- [Happy New Year!](https://atastypixel.com/happy-new-year/) - Hey folks - well, no post today, I’m afraid! To be perfectly honest, I’ve been playing Call Of Duty. Feels weird to be doing much work stuff at this time of year! Anyway: Happy New Year, and I’ll speak to you in 2015.
- [](https://atastypixel.com/annoyances/) - Just a short one this week (I’ve been Audiobussing/Xmassing), but I want to ask you about what annoys you right now in music tech.
- [](https://atastypixel.com/class-design/) - I’m trying something new this week: I’ve been designing Loopy’s code modules, and this week I’m talking about how I plan to implement the actions/sequence stuff we’ve been talking about in past weeks. It’s gonna get a little technical - quite the learning curve for me, figuring out how to talk about software development!
- [Objective-C, or Swift?](https://atastypixel.com/objective-c-or-swift/) - I’ve been pondering what language to use to write Masterpiece, and have been vacillating back and forth over the last few days. Swift is the future! Swift – Apple’s fancy new programming language destined to replace Objective-C – is designed to make some of the more heinous errors one can make with Objective-C totally impossible.
- [](https://atastypixel.com/gadgets-sequencing/) - This week, I’ve been playing with custom on-workspace controls, and sequence tracks (which is going to be really neat).
- [](https://atastypixel.com/track-layers/) - This week, I’m talking about track layers and track editing; importing, exporting, comping, loop slicing and per-waveform muting, and a bunch of other stuff.
- [](https://atastypixel.com/sequencer-tracks/) - Whoa. Ringleader over on the Loopy forum made an incredible suggestion I wanted to share with you verbatim: Maybe a sequencer track type that could be added as an option on the design screen just like any other track? Maybe include both a “live” and more manual “step” way of configuring the sequence. It would
- [](https://atastypixel.com/iofx/) - Here’s a look at my many failed attempts to figure out audio routing in Masterpiece. Tricky business! Feedback welcome. I mentioned Sebastian Dittmann; he’s @dittsn on Twitter.
- [](https://atastypixel.com/suggestions/) - Here’re some of my favourite new suggestions from people: Tristan Maduro proposed clip-based automation (which are stored and play back with the loop, as opposed to on the global timeline). Lushr proposed iterative, looping takes, where you continually record over and over, and then pick the best takes from those recordings. Oliver proposed on-screen controls
- [](https://atastypixel.com/bindings/) - Right! Now you’re up to speed - here’s the final introductory walkthrough. Next week, I’m putting you lot to work! Stick around!

- [](https://atastypixel.com/suggestions-2/) - Wow. Some great suggestions coming in already! I have a big Evernote document full of notes. Some of my favourites: Larry Seyer over on the Loopy forum suggested putting together a bunch of pre-configured templates to match the functionality of existing looper hardware, to make transitioning over to Loopy really easy. I’ve heard a number
- [](https://atastypixel.com/intro/) - The journey begins. Stay tuned.
- [An iTunes Connect screenshot management workflow](https://atastypixel.com/an-itunes-connect-screenshot-management-workflow/) - Ugh - iTunes Connect is really annoying to use when it comes to screenshots. There're some third party tools out there, but it was still too hands-on for my workflow. So I wrote a little script that does the stuff I want. I have a Sketch document that exports all the screenshots, and the script
- [Beautifying code with Alfred](https://atastypixel.com/beautifying-code-with-alfred/) - Here's an Alfred workflow which will perform some prettifying code alignments in the currently-selected text when a hotkey is pressed. It works on instance and struct members, assignments and hey, maybe other things. Yay, prettier code! Perform Code Alignment.alfredworkflow Here's a video of it in action:
- [Loopy update and the launch of Ableton Link!](https://atastypixel.com/loopy-update-and-the-launch-of-ableton-link/) - Loopy's been updated! First of all: Reverb. Loopy now has reverb FX, which you can tweak in Settings. Think of it as a very modest little preview of things to come in Loopy Masterpiece Edition. But the most exciting thing is that the update introduces support for Ableton Link which has launched today and –
- [](https://atastypixel.com/a-few-people-mentioned-that-they-wanted-to-see-the/) - A few people mentioned that they wanted to see the technical stuff that I discarded from the last video. I promise nothing, but here it is, sans-Benny Hill theme music.
- [](https://atastypixel.com/ive-just-finished-working-on-loopys-audio/) - I’ve just finished working on Loopy’s audio playback system, which streams the various layers that make up a track from disk. This episode I’m talking about how that works, and how I’m handling quality control.
- [](https://atastypixel.com/recording-and-test-driven-development/) - Building stuff! I’ve been working on track recording and layering lately. This episode I’m talking about the complexities involved in non-destructive layering, and how I’m making sure everything’s rock-solid via unit testing.
- [](https://atastypixel.com/im-doing-science-and-im-still-alive/) - Not dead, you guys. Just working on something I’m not quite ready to show you yet. It’ll be worth the wait, though.
- [](https://atastypixel.com/action-dispatching/) - Back home again, and working on Loopy Masterpiece’s action infrastructure: this is how Masterpiece’s universal action triggering and sequencing is probably going to function, allowing for a non-destructive workflow and performance automation, among other cool things.
- [](https://atastypixel.com/data/) - I’ve been doing some work under the hood this week: working on Loopy Masterpiece’s data model and figuring out how sessions are going to be stored on disk. The answer: Core Data.
- [](https://atastypixel.com/prototyping-graphics-affordance/) - Some more progress on Masterpiece’s prototype, although I got a little tiny bit lost on a tangent. This week I’m talking about graphics performance and reacquainting myself with OpenGL, and affordance in animation. Also, I found an amusing little piece of memorabilia.
- [](https://atastypixel.com/squandering-the-creative/) - Well, this week didn’t go quite as planned. I think I broke my own spirit. Oh well! Maybe next week.
- [](https://atastypixel.com/prototyping/) - I’m back, and doing some prototyping this week. Look! It moves! Stick around (and be sure to subscribe) if you’re interested in trying out the prototype app when it’s ready.
- [Nope!](https://atastypixel.com/nope/) - Well…Looks like this week’s a wash – it’s been all taken up with assorted other responsibilities. Next week! I feel good about next week.
- [](https://atastypixel.com/redesign-2/) - I’ve done some more work on the revised design this week, exploring track screen ideas: editing, and track settings, where you can select between live audio input, Inter-App Audio, and – you’ll like this – MIDI, with a twist. Some fun stuff in here. Lemme know what you think.
- [](https://atastypixel.com/a-second-design-pass/) - I’m finally getting back to Masterpiece, and taking another crack at the design. Not got much to show yet (mostly due to this week’s brain-deadness), but this week I’m talking about my motivations for this design iteration.
- [NSBrief » Michael Tyson](https://atastypixel.com/nsbrief-michael-tyson/) - NSBrief » Michael Tyson NSBrief’s Janie Clayton interviewed me last week – we talk about Loopy, Audiobus, travelling Europe in a motorhome, and other bits and pieces.

Just putting the finishing touches on over the last couple of days. Itching to get back to Masterpiece: I’m planning on doing another design pass, now I’ve had a bit of space to think about it. Stay tuned.
- [](https://atastypixel.com/errands-2/) - I’m still working on other stuff this week, but I wanted to tell you about some nice performance gains I’ve made in Loopy today.
- [](https://atastypixel.com/2803-2/) - Ableton Link: it’s gonna be huge! Stay tuned for more announcements soon.
- [](https://atastypixel.com/2807-2/) - Spent a brilliant few hours with Dub Fx jamming out some rather splendid beats with Loopy.
- [](https://atastypixel.com/2813-2/) - I've been spending some time with renowned live-looper and all round cool dude Dub Fx, talking about Loopy Masterpiece and future projects. Along the way, we made an awesome App Preview video for Loopy on the App Store. Here's something else we shot at the same time.

I've just released Version 1.6, which (uh, finally!) adds support for the iOS share sheet, bringing support for Facebook sharing, AirDrop, Messages, Mail, Dropbox, and opening in any compatible app. Should make it a bit easier to get your creations out of Loopy and into the world. Now back
- [](https://atastypixel.com/2830-2/) - If you're interested in the technical details around how music apps get made, this is an excellent talk by music technologist Greg Cerveny on creating music apps. He's interviewed a bunch of developers (including the developers of Patterning, Fugue Machine, Elastic Drums, and me) about their process and their background, and these are the results.
- [Four common mistakes in audio development](https://atastypixel.com/four-common-mistakes-in-audio-development/) - This is a discussion of four common mistakes that audio developers make, how to do better, and how to detect whether there's a problem. It's written primarily for developers, but should be accessible to non-developers too. I introduce Realtime Watchdog, a diagnostic tool for developers, and provide a brief survey of popular audio libraries. Making
- [Loop the World](https://atastypixel.com/loop-the-world/) - Musician and Loopy user Gaspard Bonnefoy has just set out on an adventure around the world, live-looping with people from all around the planet. His first stop is Dubai, where he met up with sax player Daniel Contreras. Definitely a journey worth following! (Facebook, YouTube)
- [Local Continuous Integration Setup With Git Post-Commit Hook Script](https://atastypixel.com/local-continuous-integration-setup-with-git-post-commit-hook-script/) - I have lots unit tests, but I don't have a Continuous Integration server setup, and I sometimes forget my tests are there. I know. Bad me. I was up late last night getting some failing unit tests to pass again, after forgetting I even had unit tests. Ugh. This would have been much easier if
- [Announcing: Samplebot](https://atastypixel.com/announcing-samplebot/) - Hello, friends! I've finally emerged from the depths of coding – and, I might add, the joyous but rather engaging throes of new parenthood of a quite charming little boy! – to make an announcement. No, it's not what you think: Loopy Masterpiece Edition, now named Loopy Pro, is still a little ways off. But

- [Parsing iOS watchdog 0x8badfood hang reports](https://atastypixel.com/parsing-ios-watchdog-0x8badfood-hang-reports/) - During beta testing of Loopy Pro, a tester had the misfortune to come across a hang-on-launch bug of the "exhausted real (wall clock) time allowance" kind that I couldn't reproduce at all. Annoyingly, when that happens, iOS often produces an unusable "ips" crash log which doesn't at all resemble the normal, symbolicate-able kind – it's
