Too many instruments in MIDI file created with Musescore (visible after uploading for example to Synthesia)

• Apr 30, 2021 - 11:02

Hello,
I have sheet music in Musecore just for flute (melody) and piano (bass + chords). I export it as midi.
This midi is loaded into Synthesia. I always make the setting in "Hands, Colors, and Instruments" in Synthesia at the beginning.

I don't know why then there are often a bit too much of instruments. This time it's really much too much - ie there are many more instruments than just one flute and one piano.

I'm attaching screenshot of the beginning of the notes in Musescore and a screenshot of Synthesia.
I don't know why there are so many instruments (I suppose it's a bug) and I don't have the enough strength to figure out so many positions, which of them should I change as flute or as piano.

In the screenshot from Synthesia you can see a lot of different channel numbers - where did they come from? I've never set anything up like this.
Can I do something somewhere earlier in Musescore so that there are as many channels as I have staff or a many as I had instruments (for example flute and piano)?

What can I do to avoid this now and in the next songs?

I will be very grateful for your help
Regards

If you look in the mixer of that score, you'll see you can expand each track and it indeed reveals a plethora of subchannels there.

The reason is that your score is littered with "instrument change" texts for some reason (god knows why, because each subchannel has the exact same identical playback settings). You'll notice them if you turn on "View → Show Invisible".
Also note that you have a duplicate volta at m63, best remove on of them.

See the attached where I've removed those elements.
