I am using Python and Music21 to code an algorithm that composes melodies from input music files of violin accompanied by piano pieces.My problem is that when I input a midi file that has two instruments, the output is only in one instrument. I can currently change the output instrument to a guitar, trumpet etc. even though those instruments are not present in my original input files. I would like to know whether I could write some code that identifies the instruments in the input files and outputs those specific instruments. Alternatively, is there any way that I could code for two output instruments rather than one? I have tired to copy the existing code with another instrument but the algorithm only outputs the last instrument detected in the code.Below is my current running code:
def convert_to_midi(prediction_output):
offset=0
output_notes=[]
#Create note and chord objects based on the values generated by the model
for pattern in prediction_output:
#Pattern is a chord
if ('.' in pattern) or pattern.isdigit():
notes_in_chord=pattern.split('.')
notes=[]
for current_note in notes_in_chord:
output_notes.append(instrument.Guitar())
cn=int(current_note)
new_note=note.Note(cn)
notes.append(new_note)
new_chord=chord.Chord(notes)
new_chord.offset=offset
output_notes.append(new_note)
#Pattern is a note
else:
output_notes.append(instrument.Guitar())
new_note=note.Note(pattern)
new_note.offset=offset
output_notes.append(new_note)
