[sdiy] modding for LFO retrigger

[Mark Rivera]

General question since I have only general knowledge about the intended 
target LFO..

Are all LFOs topologies designed such that poking a particular place in 
them with 0V or 5V (or similar) will cause them to retrigger (i.e., 
reset the cycle)?

Target synth is a Vermona Perfourmer, which has four monosynths with 
free-running LFOs. I'd like to be able to retrigger the LFO on one or 
two of them to implement a sort of MIDI-hard-sync'd LFO.

I thought maybe this could be achieved by adding a small PIC-based 
sub-circuit which would add a second MIDI input listening for clock 
ticks, and a switch for selecting 16th/8th/4tr or similar retrig times. 
Retrig would be affected via a DG403 analog switch (?).


cheers,
Mark
