Subject: Answered my own question

john.boys,

I take it all back. I was misreading the code. Indeed, both the
onboard sequencer clock and the MIDI time code operate with the same
clocking rules.

So the LFO's will oscillate at the same rates regardless of the sync
source.

But I do have another question. Do you just want LFO2 (VCF) to sync
with the sequencer? Or do you want LFO1 (DCO MG) to do so as well?

Mike.
