Oscillator module phase sync

Can anyone please help?

I have an oscillator module set up as a tempo sync lfo to modulate various controls on my instrument.

I want the phase to start from its beginning each time a note is pressed.

I've tried setting the Sync X-Fade to false thinking this would do the trick but it doesn't.

Any help would be very much appreciated.

(I'm using SynthEdit 1.1 for this project, not the new version.)

You can set the Phase-Mod pin to change the phase the Osc sync restarts to.

Thanks for that Jef.

I perhaps didn't explain what I want to happen clearly enough though.

Is there a way to stop the oscillator running continuously and only start with a note on (MIDI keyboard pressed)?

If you want something monophonic (like an LFO) to trigger or sync to note-on messages, then you need to construct a "MIDI to Gate" circuit, what this is extra container with it's own MIDI-to-CV except set it's polyphony to "1" and its mode to "Mono" (using Polyphony-Control module). Then pass the gate signal out of the container, this gives you a monophonic gate signal inside a polyphonic instrument. It is useful for triggering stuff that is otherwise monophonic.

If what you mean is to save CPU by switching-off the LFO when no notes are playing, then SE's Osc does not support that, 3rd-party modules sometimes do support an "On/Off" pin though.

Hope I understood the question.

Thanks Jef, that's perfect.
