Suggestion: support generation of MIDI files/data as alternate output and input variant

[abufrejoval]

Sorry, if it's already there...

And somewhat similar to inpainting with stable diffusion, the ability to chain or insert to MIDI or audio input would be great.

Next on the list would be things like transformations like "add choral lines, use this as soprano/alto/tenor/bass voice", or add a 2nd overture theme to this primary, find a transition between these two parts etc.
