syncing lfo to MIDI

[Stewart Pye]

Howdy...

It should be simple enough to just reset the integrator on a 16th, 1/4 note
or whatever, the problem is the level of the LFO output will be changing
with frequency. I guess you could reduce this effect by having a voltage
controlled OSC, calculating the voltage required depending on the
frequency. This is a bit comlpex for an LFO though.

I'm guessing the midi-cv converters with synced LFO's use a software LFO,
they've already got the DAC's there so it doesn't cost much at all.

Stewart.
