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 more.
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.
