[music-dsp] magic formulae
Does anyone have any references for magic formulae for synthesis (I am not sure that this is the usual term)? What I mean is the type of bit manipulation that generates rhythmic/pitch patterns etc., built (as far as I can see) a little bit on an ad hoc basis, like kt*((kt12|kt8)63kt4)” etc. If anyone has a suggestion of papers etc on the subject, I’d be grateful. Thanks!

Apart from an article in arXiv written by viznut, I had no further luck finding papers on the subject (the article was from 2011, so I thought that by now there would have been something somewhere, beyond the code examples and overviews etc.). It seems a cellular automata 1D with a loop of rules for any cell, where a rule is determined by a bitwise operation. A generic example with only one byte (mask could fix the number of the states with a int): start 1 1 0 1 0 0 1 0 rule 1 x x x x x x x x rule 2 x x x x x x x x ... rule n 0 1 0 0 1 0 1 1 rule 1 x x x x x x x x rule 2 x x x x x x x x ... rule n 0 1 1 1 0 1 1 0 rule 1 x x x x x x x x ... and I presume the possible effects follow the four Wolfram's classes (limit points, cyclic pattern, chaotic and more complex behaviour). -- 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
Re: [music-dsp] magic formulae
I've experimented with this using LuaJIT, which has bitwise operations. I used a LuaJIT binding to PortAudio for real time audio output. Ivan send you my stuff if you like.

You might check this out.

What exactly are you looking for Victor? Perhaps this stuff had its peak in the 80s in video games (maybe there is an article in one of the Audio Anecdotes books, if I remember correctly). There was a discussion on ACMA-L a while back discussing that it was being done in the 70s too.

Re: [music-dsp] magic formulae
Anything really, but technical articles would be welcome. I thought someone would have written something on this for ICMC, SMC, etc. Dr Victor Lazzarini Dean of Arts, Celtic Studies and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 On 27 Nov 2014, at 23:24, Ross Bencina rossb-li...@audiomulch.com wrote: On 28/11/2014 12:54 AM, Victor Lazzarini wrote: Thanks everyone for the links.
