.TH CHPRESS 1 "MIDI"
.SH NAME
chpress - generate MIDI channel pressure (after-touch) commands
.SH SYNOPSIS
.B chpress
[\fB-d\fP#] chan\fB=\fPamt ...
.SH DESCRIPTION
.I Chpress
generates channel pressure (a.k.a. "after-touch")
commands on one or many MIDI channels.
\fIChan\fP is a decimal number from 1 to 16 and \fIamt\fP is a decimal
number between 1 and 127 (inclusive).
Example:
.Cs
play "|chpress 1=0 16=127"
.Ce
If a Yamaha DX7 is assigned MIDI channel 1 and a Casio CZ-101 is assigned
MIDI channel 16, this command will turn off any after-touch in the DX7
and set the CZ-101's after-touch to maximum.
.PP
By default, the after-touch 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.
