This makes me think: instead of having a groovebox & midi to cv converter
to create tap tempo for an MOTM LFO, what about having some sort of
dedicated external controller that could perhaps be integrated into a larger
controller with joysticks etc.? I have no idea what this would take, but it
seems like a good idea to me.
