That page has some interesting examples. Here's something similar to
the Polyrhythm one done in Chuck and LiCK
polyrhythm.ck:
class Pattern extends FloatProcedure
{
dur step;
float freq;
float pan;
SinOsc sin;
fun void connect()
{
sin => Echo e => Pan2 p => dac;
0.2::second => e.delay;
pan => p.pan;
freq => sin.freq;
0.0 => sin.gain;
}
fun void run(float value)
{
0.5 => sin.gain;
step => now;
0.0 => sin.gain;
}
}
Pattern right;
0.25::second => right.step;
440 => right.freq;
0.5 => right.pan;
right.connect();
Pattern left;
1::second / 6 => left.step;
330 => left.freq;
-0.5 => left.pan;
left.connect();
spork ~ Loops.loop(right, right.step, 18::second).run();
spork ~ Loops.loopN(Loops.loop(left, left.step, 16::second), 0::ms,
2::second, 1).run();
10::second => now;
<<<"done">>>;
The loop methods are
loop(FloatProcedure, wait between procedure calls, total length of time to loop)
and
loopN(Procedure, wait between procedure calls, initial offset, number
of times to loop)
