DESCRIPTIONjack_umidi is a daemon that provides access to raw USB/socket MIDI
devices via the Jack system. The daemon will not exit when a device
becomes unavailable, but will wait until the device re-appears again.
The following options are available:
-k Terminate the client when the first capture or playback device is
no longer available. Else the client will try to re-connect.
-B Run the client in background mode.
-S Create 16 JACK subdevices for the capture device. One for each
MIDI channel.
-d Specify the device name of the USB device to use, for example
/dev/umidi0.0 .
-C Specify the capture only device name of the USB device to use,
for example /dev/umidi0.0 .
-n Specify a custom port name when registering with the JACK server.
The default value is "jack_midi".
-P Specify the playback only device name of the USB device to use,
for example /dev/umidi0.0 .
-U Specify which JACK user the program should attach to. Default is
same as running user.
-h Print help text showing available options.
