# 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
|
