.SH NAME
cntl - generate MIDI channel control commands
.SH SYNOPSIS
.B cntl
[\fB-d\fP#] chan\fB,\fPcntl\fB=\fPvalu ...
.SH DESCRIPTION
.I Cntl
generates "control" commands to set control parameters on one or
many MIDI channels.
\fIChan\fP is a decimal number from 1 to 16,
\fIcntl\fP is a decimal number from 0 to 127,
and \fIvalu\fP is a decimal number between 0 and 127 (inclusive).
Example:
.Cs
play "|cntl 1,5=0 16,7=32"
.Ce
If a Casio CZ-101 is assigned MIDI channel 1 and a Yamaha DX7 is assigned
MIDI channel 16, this command will set the portamento time to 0 on
the CZ-101, and set the volume to 32 (half) on the DX7.
.PP
By default, the control change code(s) will be followed by a pause
(120 MIDI clocks).
The \fB-d\fP option sets the amount of delay;
\fB-d0\fP suppresses the delay altogether.
