Basically, I'm trying to add two midi files, and there is no information on the Internet about this, so I'm trying to use my own.
What I have done so far, I have added two midi messages (a type of midi data) and I have a list of both midi messages. This means that I have all the data in which I need to combine the two midi. The problem is that I cannot add data in a specific format.
So my code is:
from mido import MidiFile, MidiTrack
mid = MidiFile('har.mid')
mid2 = MidiFile('har2.mid')
l = [msg for track in mid.tracks for msg in track]
l.pop()
ka = [msg for track in mid2.tracks for msg in track]
ka.pop()
result = l + ka
for messagess in result:
print(messagess)
I get this output:
note_on channel=0 note=59 velocity=40 time=0
note_on channel=0 note=60 velocity=40 time=0
note_on channel=0 note=64 velocity=40 time=0
note_off channel=0 note=59 velocity=0 time=55
note_off channel=0 note=64 velocity=0 time=0
note_on channel=0 note=52 velocity=40 time=0
note_off channel=0 note=60 velocity=0 time=55
note_on channel=0 note=64 velocity=40 time=0
note_on channel=0 note=67 velocity=40 time=0
note_off channel=0 note=67 velocity=0 time=55
note_on channel=0 note=57 velocity=40 time=0
note_off channel=0 note=52 velocity=0 time=55
note_off channel=0 note=57 velocity=0 time=0
note_off channel=0 note=64 velocity=0 time=0
note_on channel=0 note=57 velocity=40 time=55
note_off channel=0 note=57 velocity=0 time=55
note_on channel=0 note=64 velocity=40 time=0
note_on channel=0 note=67 velocity=40 time=0
note_off channel=0 note=64 velocity=0 time=55
note_off channel=0 note=67 velocity=0 time=0
note_on channel=0 note=57 velocity=40 time=110
note_on channel=0 note=64 velocity=40 time=0
note_off channel=0 note=57 velocity=0 time=55
note_off channel=0 note=64 velocity=0 time=0
note_on channel=0 note=62 velocity=40 time=0
note_off channel=0 note=62 velocity=0 time=55
note_on channel=0 note=57 velocity=40 time=110
note_on channel=0 note=62 velocity=40 time=0
note_off channel=0 note=57 velocity=0 time=55
note_off channel=0 note=62 velocity=0 time=0
note_on channel=0 note=60 velocity=40 time=0
note_on channel=0 note=62 velocity=40 time=0
note_on channel=0 note=67 velocity=40 time=0
note_on channel=0 note=60 velocity=40 time=55
note_on channel=0 note=64 velocity=40 time=0
note_off channel=0 note=60 velocity=0 time=55
note_off channel=0 note=62 velocity=0 time=0
note_off channel=0 note=64 velocity=0 time=0
note_off channel=0 note=67 velocity=0 time=55
note_on channel=0 note=64 velocity=40 time=0
note_off channel=0 note=64 velocity=0 time=55
note_on channel=0 note=60 velocity=40 time=0
note_off channel=0 note=60 velocity=0 time=55
note_on channel=0 note=62 velocity=40 time=0
note_off channel=0 note=62 velocity=0 time=55
note_on channel=0 note=64 velocity=40 time=0
note_off channel=0 note=64 velocity=0 time=55
note_on channel=0 note=60 velocity=40 time=110
note_on channel=0 note=62 velocity=40 time=0
note_off channel=0 note=60 velocity=0 time=55
note_off channel=0 note=62 velocity=0 time=0
note_on channel=0 note=48 velocity=40 time=110
note_on channel=0 note=62 velocity=40 time=0
note_off channel=0 note=48 velocity=0 time=55
note_off channel=0 note=62 velocity=0 time=0
note_on channel=0 note=57 velocity=40 time=55
note_on channel=0 note=60 velocity=40 time=0
Now this is fine, but the problem is that I can add tracking messages to this format:
from mido import Message, MidiFile, MidiTrack
mid = MidiFile()
track = MidiTrack()
mid.tracks.append(track)
track.append(Message('program_change', program=12, time=0))
track.append(Message('note_on', note=64, velocity=64, time=32))
track.append(Message('note_off', note=64, velocity=127, time=32))
mid.save('new_song.mid')
so my question is: how to add each line from this format:
note_off channel=0 note=62 velocity=0 time=0
into this format
'note_off', note=62, velocity=0, time=0
in track.append(Message())
because track.append only supports this format:
track.append(Message('note_off', note=62, velocity=0, time=0))
Thanks in advance.
