- Yes, the MIDI tracks are polyphonic. A single step can hold and play a note or a chord. Notes and chords on successive steps can overlap, so the one limitation here is the polyphony of the instrument on the other end of the MIDI cable.
- The onboard chords from the pre-programmed list are holding up to 7 notes. But, each step can hold (you can MIDI record notes to a step) and spit up to 30 MIDI notes at the same time.
