mididings - MIDI router and processor


mididings [options] "patch"

mididings [options] -f filename


mididings is a MIDI router and processor based on Python, supporting ALSA and JACK MIDI.

Many features are provided:

MIDI routing and filtering
Filter events depending on their event type, channel, note number, velocity, etc.,
and freely route them between an arbitrary number of input and output ports.

Modifying and converting MIDI events
Transpose notes, apply velocity curves, change controller values and ranges, or
convert events to any other MIDI event type. mididings also includes more complex
functions like a diatonic harmonizer, floating split points, latched notes, and

Seamless switching between patches
Set up different "scenes", each with its own MIDI routing and processing, and
switch between them at any time, even while playing. Switching scenes does not
affect notes already held, and does not result in dropouts or stuck notes!

MIDI event monitoring, running external commands
Print MIDI event data to the console to help debugging your patches and configuring
your MIDI controllers. In addition to its MIDI output, mididings can also execute
shell commands and send OSC or DBUS messages.
