I've had headaches also trying to get ADSR's to fire in divided sync (A-
160) from either my A-190 or Kentons and it never was right.

The final solution: The Flame Clockwork

This box does it all. Rock solid sync to midi and 3 gate outs that do
regular beats, triptets and dotted. There's also a multi output that
combines all three. Plus, with CV outputs, LFO's, Random and a Midi to
CV converter. I've never had better timing before. This is the master
clock we've been waiting for made for musicians.
