pseudo factorial
Pseudo factorial sequencer. Every time trig is activated, the sequencer goes one cycle forward. At every cycle the output is calculated with the formula o=i*(i+a+1), where i is the preceding output. At reset i=1 unless i0 is connected.
Inlets
int32 first number of the serie
int32 a coefficient in the formula
bool32.rising trigger
bool32.rising reset
Outlets
int32 output
