One option is to use a smart button to send the commands for your keyboard. You can then always just trigger the smart button at the start of the song if needed.

Great idea Mike. Smart buttons work perfectly for this.
Then I tried to make another smart button to stop MIDI song and „rewind“ it to beginning, but it didn't work. Nor listening to commands from keyboard (stop and rewind), nor using built-in commands Start MIDI and Stop MIDI didn't work. I don't know why.
