Description

Sends MIDI program change messages at i-rate

Syntax

outipc ichn, iprog, imin, imax

Initialization

ichn -- MIDI channel number (1-16)

iprog -- program change number in floating point

imin -- minimum floating point value (converted in MIDI integer value 0)

imax -- maximum floating point value (converted in MIDI integer value 127 (7 bit))

Performance

outipc (i-rate program change output) sends program change messages. It works only with MIDI instruments which recognize them. It can drive a different value of a parameter for each note currently active.

It can scale an i-value floating-point argument according to the imin and imax values. For example, set imin = 1.0 and imax = 2.0. When the ivalue argument receives a 2.0 value, the opcode will send a 127 value to the MIDI OUT device. When the ivalue argument receives a 1.0 value, it will send a 0 value. i-rate opcodes send their message once during instrument initialization.

Examples

Here is an example of the outipc opcode. It uses the file outipc.csd.

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac -Q1 -M0  ;;;realtime audio out and midi in and out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o outipc.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100
ksmps = 32
nchnls = 2

outipc 1, 80, 0, 127	;program change --> 80
