MusicalPi

A program for the RaspberryPi to play MIDI files on MIDI devices.

This program just sends MIDI data contained in a MIDI file to a connected MIDI device and also supports mapping program patch numbers.

Program Patch Number Mapping

A mapping file looks like this

0:1
1:1
4:7

This would map program patch numbers 0, 1 and 4 in the MIDI to the patch numbers 1, 1 and 7. Those are the numbers ultimately sent by the program. Numbers not listed stay unchanged.

Every line is one mapping, and has the format from:to

This lets you change the instruments contained in a MIDI file

Usage

`./musicalpi [-m mapping_file] midi_file
