Kawai CN34 MIDI

[arpegione]

Hello,
I have a CN34 Kawai model with this feature : "The piano includes a 2-track recorder, which lets you record right and left hand parts separately, or record using two different voices, play them back as a single piece and practice left and right-hand parts separately"
My question is, how can I modify/edit an external MIDI file, load it into piano player via USB device, and practice left and right-hand parts separately ?
Many thanx,
Marian

With digital pianos, usually the two track recording is audio, not midi. the only input is from the keys. Also, midi is a 16 channel feature, it does not make sense to apply only two tracks for a midi input when a vast majority of midi files use more than two.
