What is midish?

Midish is an open-source MIDI sequencer/filter for Unix-like operating systems (developped and tested on OpenBSD and Linux). Implemented as a simple command-line interpreter (like a shell) it's intended to be lightweight, fast and reliable for real-time performance.

Important features:

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

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