NAME - JACK Plumbing Daemon SYNOPSIS [options] [rule-files] OPTIONS
-d : Do not operate as a daemon. -o : Do not load ordinary rule files. -q : Quiet operation. -u : Set the time, in micro-seconds, that must elapse after a connection notification to indicate the end of a notification set (default=30000). This is an optimization switch. DESCRIPTION maintains a set of port connection rules and manages these as clients register ports with JACK. Port names are implicitly bounded regular expressions and support sub-expression patterns. There are four rules: connect, disconnect, also-connect and connect-exclusive. (connect "SuperCollider:out_(.*)" "system:playback_1") This connect rule ensures that whenever scsynth(1) is running any output ports it registers are connected to appropriate ALSA playback ports. The connect rule only makes a connection if none already exist. (also-connect "system:playback_1" "jack.udp-[0-9]*:in_1") This also-connect rule ensures that when jack.udp(1) is running in send mode all signals that are ordinarily sent to the local audio interface will also be sent to the network destination. The also-connect aliasing applies to both the left and right hand side of connect rules. (connect-exclusive "SuperCollider:out_(.*)" "ardour:sc3_in_1/in 1") This connect-exclusive rule ensures that if SuperCollider and an ardour(1) session with appropriate tracks are both running that SuperCollider gets connected to ardour and disconnected from everything else. This type of connection daemon has the following advantages over both environment variables and command line arguments: o it does not require any client connection support or logic at all o it provides a uniform user interface to all clients o it has a somewhat declarative style This type of daemon is very lightweight and non-intrusive: it requires no arguments, it runs from an unprivileged thread, if the rule set is empty it is a no-op, it does not write any files, it does not require any modification to clients or to how clients are started. When a set of port registrations is made it checks the modification time of the rule set files, /etc/ and ~/, and any files specified by the user, rereads the rule set if it has been updated, then makes the JACK graph obey the rules. Any lines beginning with a semi-colon are ignored. The rule set is sorted, disconnect rules are applied first, then connect rules, then connect-exclusive rules. FILES

klick - An advanced metronome for JACK SYNOPSIS
klick [options] [bars] [meter] tempo[-tempo2/accel] [pattern] klick [options] -f filename klick [options] -i klick [options] -j DESCRIPTION
klick is an advanced command-line based metronome using the JACK sound server. It allows you to define complex tempo maps for entire songs or performances. A single meter and tempo can be specified on the command line, while more complex tempo maps can be read from plain text files. Alternatively, it's also possible to run klick in interactive mode, where the tempo can be changed at runtime using the keyboard, or to follow tempo information read from JACK transport. OPTIONS
-f filename load tempo map from file -j no tempo map, just follow jack transport -n name set jack client name -p port,.. jack port(s) to connect to -P automatically connect to hardware ports -o port OSC port to listen on -i interactive mode -W filename export click track to audio file -r samplerate sample rate of export (default: 48000) -s number use built-in sounds: 0: square wave (default) 1: sine wave 2: noise 3: acoustic bell/click -S file[,file] load sounds from file(s) -e no emphasized beats -E emphasized beats only -v mult[,mult] adjust playback volume (default: 1.0) -w mult[,mult] adjust playback pitch (default: 1.0) -t enable jack transport -T become transport master (implies -t) -d seconds delay before starting playback -c bars pre-roll. use -c 0 for 2 beats -l label start playback at the given label -x multiplier multiply tempo by the given factor -h show help TEMPO MAP FILE FORMAT
