LPGmix
combination of a crossfader and a lowpass gate When input v goes up, crossfades from sine input to harmonics input, while opening up the filter cutoff on the harmonics input.
Inlets
frac32 gain input
frac32buffer audio input
frac32buffer harmonics
Outlets
frac32buffer output
Declaration
int32_t prev;
int32_t step;
int32_t val;
Control Rate
step = (inlet_v - prev) >> 4;
int32_t i = prev;
prev = inlet_v;
int32_t freq;
Audio Rate
MTOF(i - (1 << 26) << 1, freq)
val = ___SMMLA((inlet_harmonics - val) << 1, freq, val);
int32_t out = ___SMMUL(i << 3, val - inlet_sine << 2) + inlet_sine;
outlet_o = ___SMMUL(out << 3, i << 2);
i += step;
