NAME

a2jmidid - JACK MIDI daemon for ALSA MIDI

SYNOPSIS

a2jmidid [-j jack-server] [e | --export-hw]

DESCRIPTION

a2jmidid is a daemon that implements automatic bridging. For every ALSAsequencer port you get one jack midi port. If ALSA sequencer port isboth input and output one, you get two JACK MIDI ports, one input andoutput.

OPTIONS

-e | --export-hw: forces a2jmidid to bridge hardware ports as well as software ports
-u: forces a2jmidid to generate non-unique port names (see NOTES)
-j: specifies which jack-server to use

NOTES

ALSA does not guarantee client names to by unique. I.e. it is possibleto have two apps that create two clients with same ALSA client name.JACK however requires port names to be unique. To ensure this uniqueness,a2jmidid will add the unique numeric ALSA client ID to the JACK port name.However this behaviour is known to be problematic when restoringconnections using simplistic tools like aj-snapshot and jack_connect.In order to make them work, the -u option can be used. This option willcause a2jmidid to omit the numeric ALSA Client ID from JACK port names.In this mode, ALSA client name uniqueness must be guaranteed externally.
