Same issue here, when connected through cv/gate my Oberheim SEM was triggering poorly (out of time with the sequence). It turned out the gate voltage was too strong and when I ran the gate cable through a passive attenuator (a potentiometer) and "turned it down" to about 70% it began triggering correctly (in time). At full strength, the BSP gate causes the SEM to overload, only triggering when the key is released, making any programmed sequence to sound out-of-time. It would be nice if the BSP software allowed the maximum gate voltage to be adjusted between 5-10 volts. Otherwise I am extrememly happy with everything about my new Beatstep Pro (Shhhh, I would've paid more for this little box).
