## outkpat

outkpat — Sends polyphonic MIDI aftertouch messages at k-rate.

## Description

Sends polyphonic MIDI aftertouch messages at k-rate.

## Syntax

    outkpat kchn, knotenum, kvalue, kmin, kmax

## Performance

kchn -- MIDI channel number (1-16)

knotenum -- MIDI note number (used in polyphonic aftertouch messages)

kvalue -- floating point value

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

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

outkpat (k-rate polyphonic aftertouch output) sends polyphonic aftertouch 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 the k-value floating-point argument according to the kmin and kmax values. For example: set kmin = 1.0 and kmax = 2.0. When the kvalue argument receives a 2.0 value, the opcode will send a 127 value to the MIDI OUT device. When the kvalue argument receives a 1.0 value, it will send a 0 value. k-rate opcodes send a message each time the MIDI converted value of argument kvalue changes.

Thanks goes to Rasmus Ekman for pointing out the correct MIDI channel and controller number ranges.
