granular music recommendations?
by AlgoMantra 23 Jul '24

23 Jul '24

Yo All....I'm trying to download and study some of the best music out there which features granular synthesis. I haven't heard much yet beyond Iannis Xenakis, but I'd love to know what your favorites are. Perhaps it would be worthwhile putting up a torrent of the same. If possible, kindly provide links to mp3 files or any other type of free downloads. (What do you think of Jaron Lanier's music?) http://www.jaronlanier.com/musicdownload.html cheers! ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

Scale & diatonic
by Hans Aberg 12 Oct '11

12 Oct '11

I have made a program, scale.ck, that admits one to work with scales, including tuning stretch, céleste tremulant, retune them, and then save to a file, with a line of code that can be pasted back into the source, available at next program startup. Scale tunings can be put into tuning banks, and otherwise defined by your favorite method. Details in the file. I have also updated my program for diatonic tuning systems, diatonic.ck. Just a few changes: adding some common tunings, fixing typos. The files are available here: http://www.math.su.se/~haberg/tuning_systems/ Hans

continuous random values
by Thomas Girod 28 Sep '10

28 Sep '10

Hi there. I am looking for some kind of "random lfo" to change a parameter continuously and randomly. I remember there is a UGen called "LFNoise2" to do that in SuperCollider. How can I do that with ChucK ? thanks tom

good until loop
by Timothy Leonido 28 Sep '10

28 Sep '10

Would anyone mind sending a good example for loop "until" ? I simply want a shred to stop automatically after a 10 seconds. Here is what I wrote: do{ Std.rand2f(200,50.0) + Math.sin(v*100.0)*20.0 => v2 => f.pfreq; Std.rand2f(5000.0, 60) + Math.sin(v*30.0)*80.0 => f3.pfreq; Std.rand2f(1500, 80.0) + Math.sin(v*200.0)*50.0 => f2.pfreq; std.rand2f(.551,.549)=>buf.rate; .0+(.9*maybe)=>buf.gain; 0=>buf.pos; .1:: T =>now; } until (5::second); thanks so much! -tim

random seed
by Lars Ullrich 12 Sep '10

if we use a random seed, f.e. Std.srand(120); will this affect all the random function inside the sketch? and if so, how can we turn it off? thanks

That looks like a bug, you are totally right. Good catch, Lars! Kas.

How to get better-sounding instruments?
by Tambet 11 Sep '10

11 Sep '10

Got such question: there is a set of instruments included from STK, also there are some reverbs etc., but I cant make them together do very natural sounds; I also don't want to use wav as I can't cange it's params. I do not have natural instruments to play in nor will to do so. Questions are: - Are there some good ways to connect ChucK with additional synthesizers in such way that I could get sample-by-sample output and slow down the generation of wav (with -s flag). - Are there more synthesizers built-in to ChucK. - Are there add-on modules with more instruments. - Are there examples about how to build natural sounds with those built-in oscillators and effects. As I try to get something, what would not sound too electronic or too flat. Tambet

operators
by Lars Ullrich 09 Sep '10

Dear list, Is there a way to do this operator functions in chuck? ">>" Shift all bits to the right ( has the effect of dividing a number by a power of two, but is less expensive in computer time.) "&" Bitwise intersection of two numbers. The & object performs a bit- by-bit "and" of two numbers (expressed in binary for the task). It is similar to the operator found in the C programming language. Any help will be much aprecciated!
