I was not able to get it running with my Doepfer MCV-4 nor with my Theis sequencer. The Gate was simply not working - only the first note sent a gate which then stayed 'high'.
Sent it back to MFB via the shop where I bought it (the staff and me tried to get it running with a MacBeth and a Little Phatty - same problem), it came back as 'Working now' but it didn't. Returned it and bought a Doepfer MAQ16/3.
