I knew I was going to get to this eventually; I have always wanted to
be able to ChucK a ugen to a parameter, similar to control voltages in
modular synths I suppose.
With this
public class Module extends Chugen
{
Gain _cv;
{
_cv => blackhole;
}
fun float tick(float in)
{
return tick(in, _cv.last());
}
// subclasses override this function
fun float tick(float in, float cv)
{
return in;
}
}
I can do this, which interpolates the cv to a frequency between 2.0 and 8.0
class SinModule extends Module
{
SinOsc sin;
{
sin => blackhole;
}
fun float tick(float in, float cv)
{
Interpolate.linear(cv, -1.0, 1.0, 2.0, 8.0) => sin.freq;
return sin.last();
}
}
and then this, which uses a SinOsc at a frequency of 0.25 as the cv to
modulate the frequency of the SinModule which modulates the gain for a
tremolo effect.
class TremoloModule extends Module
{
SinModule gainLfo;
SinOsc rateLfo;
{
1.0 => gainLfo.sin.gain;
gainLfo => _cv;
0.25 => rateLfo.freq;
1.0 => rateLfo.gain;
rateLfo => gainLfo._cv;
}
fun float tick(float in, float cv)
{
Interpolate.linear(cv, -1.0, 1.0, 0.0, 1.0) => gain;
return in;
}
}
SinOsc sin => TremoloModule trem => dac;
0.4 => sin.gain;
220.0 => sin.freq;
1::hour => now;

I am wondering if others have cleaner ways of doing this, because this
example isn't even easy for me to follow.
