Re: [music-dsp] looking for a flexible synthesis system technically and legally appropriate for iOS development
Hi, I'm currently working on a library (about 85% done at the moment) that does some of the things you want. I too am a SuperCollider user and once I wanted to make a clean library implementation (fork) of scsynth to use with mobile development. When I brought up the case in sc-dev mailing list, I've learned that I can't distribute my art through Apple appstore because the GPL binary distribution clauses aren't compatible with Apple agreement. So even if I provide the full source with my art, I am not allowed to distribute it in binary form if the source is GPL'ed. This was the consensus so I backed off. Now I've made a kind of lame audio server implementation which is heavily influenced by scsynth. I have nodes but they are restricted to synths at this moment so there are no groups. I've ported many of the SuperCollider UGens (recoded all of them by hand, followed through the original sources and all). I also do not have FFT (yet) and multichannel expansion like things but it is not very hard to achieve. It is easy to connect UGens to parameters of other UGens and such. I'm quite happy with it overall for the time being. The good part is that I've made the implementation in haXe (http://www.haxe.org ) language so I can target the same DSP code for Flash (Flash 10+ supports realtime audio), JavaScript (for the upcoming audio api for js in firefox 4) and I can also emit C++ code for mobile development. The performance is quite good (only tested in flash yet though, a very pessimistic ballpark would be that it is half as efficient as scsynth running in a browser with Flash). I'll open source it at some moment but not under GPL. I can use some help so if anyone is interested in helping to make it release ready, drop me a line.

Sent this a few days ago and it doesn't seem to have gone through, so trying again.) Hi There, I've been writing low-level code for my iOS app, Thicket, pretty much myself, with the exception of a sine oscillator and an envelope borrowed from STK. I'd like to be able to work on this platform in a much faster way than I have been, simply plugging unit generators in to one another, not having to stop and think about how to, for example, go from a mono oscillator signal to a stereo reverb signal. I'd like to be able to work more like I work in SuperCollider, writing higher-level code to create a signal path, trusting that the connections will be efficiently managed for me. In other words, I'd like to spend a little less time being a fairly incompetent engineer, and more time being a halfway-decent artist. I'm finding that my list of options is surprisingly small SuperCollider -- GPL licence, would require that I open-source my app ChucK -- GPL license, would require that I open-source my app CSound -- the FAQ indicates that I need to make arrangements with MIT to put it to commercial use. Worth looking in to, perhaps. JSyn -- java, not gonna work on iOS MusicKit -- looks very interesting, but doesn't seem to be a very active project, and I don't think anyone has gotten it running on iOS yet Pure Data -- seems like my best option. more permissive license, but I'm wary of the visual programming paradigm, and have at least one technical detail which is making me a bit uncomfortable Am I missing something? Is there anything -- free, or not, which I should look at for iOS development besides Pure Data? Are there not hundreds of other people with the same needs that I have? Are my options really limited to: Pure Data or rolling my own, or open-sourcing my app? I sincerely appreciate any info or thoughts any of you are able to share with me. thanks, -Morgan -- Web: http://www.morganpackard.com Music/Art: Latest album: Moment Again Elsewhere iOS app Thicket available on iTunes store. -- Web: http://www.morganpackard.com Music/Art: Latest album: Moment Again Elsewhere iOS app Thicket available on iTunes store. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp

This book is an excellent source: Andy Farnell, Designing Sound. There are code examples for Pure Data online, some of which go beyond the book.

Re: [music-dsp] Modular synthesis percussion?
If you can translate from LISP then a good start to be made here https://ccrma.stanford.edu/~sdill/220A-project/drums.html And these additive patches, like Risset's drum, are still great templates for other experiments http://www.codemist.co.uk/AmsterdamCatalog/02/index.html What I found makes a significant difference in making good percussion is having a genuine exponential envelope generator.
