I think I will use one of my circuit synth channels to control the Streichfett until I grab a keystep.
It may be slightly offtopic regarding the thread title, but the Streichfett and the Keystep make a great team, at least unless you want or need to control the two parts of the Streichfett seperately. Works absolutely flawlessly; I'm actually doing this myself, as long as one MIDI channel is sufficient
. However, controlling the Streichfett's two parts with the BSP's green and yellow
sequencers also works fine if monophony is OK.
Can't say anything about the VP-03 though, since I don't own one and have no experience with it.
Personally, I think using the BSP with a polyphonic or paraphonic synth (unless you use the drum sequencer as a melodic sequencer) is not the best of choices, simply because the BSP isn't designed for this purpose.
