vcaST
"voltage controlled amplifier", multiplies v and a inputs, with linear interpolation from k- to s-rate
Inlets
frac32 gain input
frac32buffer audio input
frac32buffer a2
Outlets
frac32buffer output
frac32buffer o2
Declaration
int32_t prev;
int32_t step;
Control Rate
step = (inlet_v - prev) >> 4;
int32_t i = prev;
prev = inlet_v;
Audio Rate
outlet_o1 = ___SMMUL(inlet_a1, i) << 5;
outlet_o2 = ___SMMUL(inlet_a2, i) << 5;
i += step;
