hm, I think with the STK demo you had to keep moving the energy slider
in the GUI to get the "rattle" to continue. have you tried sending a
sort of ramp to the energe parameter?
Basically I think as long as the energy value keeps changing the
rattle will continue.
Shakers s => dac;
Phasor lfo => blackhole;
100 => lfo.freq;
10 => s.preset;
s.noteOn(1);
now + 3::second => time end;
while (now < end) {
lfo.last()/10+0.5 => s.energy;
1::ms => now;
}
As I've just discovered you can get some cool effects by using
different frequencies and waveforms for the LFO.
