## outipb

outipb — Sends MIDI pitch-bend messages at i-rate.

## Description

Sends MIDI pitch-bend messages at i-rate.

## Syntax

    outipb ichn, ivalue, imin, imax

## Initialization

ichn -- MIDI channel number (1-16)

ivalue -- floating point value

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

outipb (i-rate pitch bend output) sends pitch bend 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 outipb opcode. It uses the file outipb.csd.
