as i understand it, this is not enough. the run_synth() method allows
you to run the synth for a continuous audio block with [MIDI] events
interspersed at arbitrary timestamps, while with midi_msg() you'd
have to split audio blocks to match event timestamps, which is messy
and performance-unfriendly.
