Examples

Basic

$ midi-m8 Songs/Demos/DEMO1.m8s

This will create a file tracks.midi.

Choose output file name

$ midi-m8 Songs/Demos/DEMO1.m8s -o output.mid

This will create a file output.mid.

Limit note length

$ midi-m8 -m 2 Songs/Demos/DEMO1.m8s

This caps the note length to 2 quarter notes.

Single track

$ midi-m8 --only-track 5 Songs/Demos/DEMO1.m8s

This will output only track 5 to track-5.midi.

Starting position

$ midi-m8 -s 02 Songs/Demos/DEMO1.m8s

This will render Midi starting from the position 02 in the song.
