Thanks for your answer Perry, Do you happen to know something about SndBuf and the members .loop and .interp and how to use them. Not many chuck users know about them.... thanks in advance!

Here’s a simple example of using a global: 1000 => float freqGlob; // global frequency variable SinOsc s => dac; // note that this osc is treated globally as well spork ~ sweep(); while (true) { // main loop randomly (re)sets freq Std.rand2f(500.0,3000.0) => freqGlob => s.freq; Std.rand2f(0.3,1.0)::second => now; } // this shred sweeps the frequency exponentially down fun void sweep() { while (true) { (0.999*=> freqGlob) => s.freq; ms => now; } } _______________________________________________ chuck-users mailing list chuck-users@lists.cs.princeton.edu https://lists.cs.princeton.edu/mailman/listinfo/chuck-users
