Waldorf Blofeld + Akai XR20 as a 3 track midi sequencer.

Akai XR20 working as a 3 track sequencer on Waldorf Blofeld. "Drum" sounds from XR20. "1 Shot" delivering the bass line on Blofeld's ch1. XR20 sounds set to zero. Cons: it only let you program notes in a single octave. "Synth" part playing on along with midi notes sent to Blofeld's ch2
