Separating the two staves of an instrument into two instruments
I have a MIDI that has the two piano staves as part of a single instrument, see screenshot 1piano.jpg
I would like to separate the two staves such that each stave is its own instrument, so that I end up with the MIDI's instruments looking like in screenshot 2pianos.jpg (screenshot comes from a different MIDI, which already has separate instruments)
Can anyone please tell me how I can do this separation using MS 1.3? I need to do this so that my keyboard can see the two staves as separate tracks, which I can rehearse separately as LH (left hand) and RH (right hand).
Many thanks in advance!
