Dear All,
I'm trying to find a suitable workflow to make my choices easier.
One idea was to compose over a piano reduction, for easier manipulation.
Here's a way of doing that, with comments.
The MIDI FILE output is like this. I did NO EDITIONS at all in Musescore.This is the video of the MIDI output.
The XML output is the piano reduction.
Very convenient !
Best,
Julio
