mio2jack is a tool to expose sndio MIDI-ports in
jack.
For now it only handles one-way communication, that is MIDI events flowing in the sndio → jack direction. Patches accepted!
usage: mio2jack [-h] [-p mio_port] [-n jack_client_name]
$ mio2jack -p midithru/0 -n sndio-midithru/0
Will expose the sndiod midithru-box midithru/0 in jack with the client name
sndio-midithru/0. That client will have a single MIDI output, from which all
MIDI events going through midithru/0 will be output.
