wow, how did they manage to do that?

I thin I have a design for a MIDI interface for it in an old Maplin
Electronics mag...

The CV input would be cool, its only 4 bit resolution tho I think. How would
you do a gate????

Yes I thought that was DEFINATELY one to try when I read that unpredictable
output results from this :)
