Midish

Midish is a MIDI sequencer/filter for Unix-like operating systems (tested on OpenBSD and Linux) implemented as a simple command line interpreter, like a shell. This application is intended to be lightweight, fast, and reliable for real-time performance.

Midish is open-source software distributed under a 2-clause BSD-style license. Currently in development (contributions are welcome), it can safely be used for sequencing and filtering.

Features:

• multiple MIDI devices handling
• synchronisation to external midi devices
• real-time MIDI filtering/routing (controller mapping, keyboard splitting, ...)
• track recording, metronome
• basic track editing (insert, copy, delete, ...)
• track quantisation
• import and export of standard MIDI files
• tempo and time-signature changes
• system exclusive messages handling
