Yes you can!
You'll need to set the BSP to send Hz/V out of the Pitch CV outputs if it is an original MS20, but if it's a reissue/mini, you should be able to use the default setting of V/Oct.
Plug Pitch CV, Velocity CV and Gate from seq 1 into VCO 1+2 CV In, Initial Gain and Trig In respectively. Plug Pitch CV into VCO 2 CV In.
From the BSP MIDI out plug into the Volca Bass MIDI in. Make sure the sequencer on the BSP you are going to run the VBass on is set to the same MIDI channel as the VBass.
Now record a sequence on the two sequencers and then hit play. Experiment with sending the Velocity of the two sequencers to different CV inputs on the MS20, or even use the Pitch CV of one of them to modulate things like the filter cutoff and the Total input.
Have some fun and let us know how you went!
