outipat — Sends polyphonic MIDI aftertouch messages at i-rate.
ichn -- MIDI channel number (1-16)
inotenum -- MIDI note number (used in polyphonic aftertouch messages)
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))
outipat (i-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 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.
