[Python] Trying to write a midi file with 2 tracks

I want to create a midi file (using midiutils) so when I open it in eg Audacity it will be two tracks, one called track 1 and one called track 2. however - it combines them into one track. I am specifying two tracks and stating file format 2 (I have also tried format 1), both should produce multiple tracks.

try and write a midi file with 2 tracks


# midi
from midiutil import MIDIFile
# now create the midi file
numTracks = 2
#track = 1
channel = 0
time = 0 # In beats
duration = 1 # In beats
tempo = 60 # In BPM
volume = 100 # 0-127, as per the MIDI standard
MyMIDI = MIDIFile(2,file_format=2) # two tracks,
MyMIDI.addTempo(0,time, tempo)
MyMIDI.addTrackName(0, time, "Track1")
MyMIDI.addNote(0, channel, 60, time, duration, volume)
MyMIDI.addTrackName(1, time, "Track2")
MyMIDI.addNote(1,channel, 62, time, duration, volume)
output_path = "D:/python_dev/test5.mid"
with open(output_path, "wb") as midi_file:
MyMIDI.writeFile(midi_file)
