AUCATCTL(1)		  BSD General Commands Manual		   AUCATCTL(1)

NAME
     aucatctl -- control aucat and/or sndiod volume through MIDI

SYNOPSIS
     aucatctl [-f port]	[expr ...]

DESCRIPTION
     The aucatctl utility sends	MIDI volume controller messages	(number	7) to
     adjust the	volume of audio	programs using sndiod(1) server	for output.
     It	can send a master volume system	exclusive messages as well to control
     the volume	of the mix of all streams.

     The options are as	follows:

     -f	port
	     Specifies the name	of the sndio(7)	MIDI port to use, default is
	     snd/0

     In	no expression is given,	aucatctl displays the list of streams known by
     the server	and their respective volumes.  If an expression	is a stream
     name, then	the volume of this stream is displayed.	 If the	expression is
     a stream name followed by "=" followed by a decimal in the	0..127 range,
     then the stream volume is set to the given	value.

     The special master	stream corresponds to the mix of all streams and sends
     master volume system exclusive messages.

EXAMPLES
     List known	volumes	knobs and their	values:

	   $ aucatctl
	   sox0=127
	   mplayer0=127
	   aucat0=127
	   master=127

     Set master	volume to 85 and mplayer volume	to 100

	   $ aucatctl master=85	mplayer0=100
	   master -> 85
	   mplayer0 -> 100
