NAME alsa-seq-server -- daemon that converts one or more raw MIDI device(s) into an ALSA sequencer server. SYNOPSIS alsa-seq-server [-F <filter>] [-d <device_name>] [-C <capture_device_name>] [-P <playback_device_name>] [-U <username>] [-G <groupname>] [-m <devicemode>] [-s <devicename>] [-i <rtprio>] [-B] [-h] DESCRIPTION alsa-seq-server is a daemon that provides access to raw USB/socket MIDI devices via the ALSA sequencer API. The daemon will not exit when a device becomes unavailable, but will wait until the device re-appears again. The following options are available: -B Run the client in background mode. -F Specify a simple device name filter, which is used to match character device entries in /dev/ . As new devices appear, they are automatically made visible to other ALSA MIDI clients. -d Specify the device name of the USB device to use, for example /dev/umidi0.0 . This option can be repeated to specify more devices. -C Specify the capture only device name of the USB device to use, for example /dev/umidi0.0 . This option can be repeated to specify more capture devices. -P Specify the playback only device name of the USB device to use, for example /dev/umidi0.0 . This option can be repeated to specify more playback only devices. -s Specify character device name for ALSA sequencer. The default is snd/seq. -U Specify username for the ALSA character device. The default is root. -G Specify groupname for the ALSA character device. The default is wheel. -m Specify mode for the ALSA character device. The default is 0666. -i priority Set real-time priority to priority. Refer to rtprio(1) for more information. -h Print help text showing available options. EXAMPLES # Start ALSA sequencer server in background mode alsa-seq-server -d /dev/umidi0.0 -B # Start ALSA sequencer server in background mode for all umidi<XXX> devices alsa-seq-server -F umidi -B # List all available ALSA sequencer ports aconnect -l # Connect two ALSA sequencer ports aconnect 1:0 2:0 SEE ALSO aconnect(1), cuse(3) TROUBLESHOOTING Check that the permissions are correct for your MIDI devices and that the cuse kernel module is loaded.
