SYNOPSIS

jack_umidi [-d <device_name>] [-C <capture_device_name>] [-P <playback_device_name>] [-n <port_name>] [-k] [-B] [-S] [-U <username>] [-h]

DESCRIPTION

jack_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.

EXAMPLES

# Start Jack MIDI client in background mode
jack_umidi -d /dev/umidi0.0 -B

# List all available JACK ports
jack_lsp

# Connect two JACK ports
jack_connect port1 port2
