This has me thinking down a similar path. I have a Roland MC-303 Groovebox.
OK, you can stop laughing now. The groovebox has a tap tempo feature, and
I've used it live as a tempo controller for my MAQ, and for delys that sync
to MIDI clock. I'm thinking I could send the MIDI output of the groovebox
to a MIDI/CV converter that has a clock output, send that to a clock
divider, and then send the subdivision output to the 320 LFO. Would I want
to go the the Sync or the CV input? What would be cool would be to have the
MIDI/CV provide the base tempo, and the Rate knob provide the subdivision.
This'd be kind of like how oscillator sync works, only in the sub-audible
range. I'm going to have to play with this when I get a chance.
