I'm trying to play two separate midi files in one project. Bronson2 I have
working fine. How should I approach bass.mid to get it to work alongside the
other file. I have a feeling it's something about Midi numbers however I'm
new to csound and unsure. I've posted the code below. I'm receiving an error
message that the midi file won't load however I've made sure it's in the
project file. Any help is appreciated, thanks.

Others will no better, but I didn't think this was possible. I've only ever seen examples of a single MIDI file loaded, but that doesn't mean it's not possible. Others, what say ye?

I would recommend mido, a Python midi library.

Richard

yes, not straightforward at all. The midifile data is played like a score, so it works a bit like the standard numeric score (where you can't have more than one in memory).

Of course you can stream rt midi data in, so an external midifile player or sequencer would do the job.

I'm guessing the fact that we don't already have one is indicative of it not being that straightforward? But I'm not really a MIDI guy..

I guess it would be nice to have an opcode to specify a midifile to run.
Would this be hard?

Meanwhile, maybe a solution would be to use an external midifile player
to feed live MIDI to Csound.
