Basic MPE questions, midiformat User Guide inconsistencies
I don't really own a mpe instrument, but I am trying to expand a Max For Live device that uses the live.step to use the extra1&2 values to effect MPE parameters in ableton instruments. eq with the Wavetable Instrument. I'm only interested in Monophonic MPE out.
I'm having trouble understanding a couple things.
1) In the midiformat object, what is the difference between "Polyphonic (Key) Aftertouch" and "After Touch"?
User Guide states: (with a small error in inlet2, that its (pressure, pitch) when I believe its (pitch pressure)
(inlet2) "Polyphonic (Key) Aftertouch"
In 2nd inlet: The first number is an aftertouch (pressure) value and the second number is a pitch value (key number), to be formatted into a polyphonic key pressure message.
Arguments:
aftertouch and pitch-value [list]
(Inlet5) "After Touch"
In 5th inlet: The value is formatted into an aftertouch (channel pressure) message.
Arguments:
aftertouch [int]
What are both commonly used for? Is AfterTouch (inlet 5) used for 'Pressure' commonly?
2) MPE Pitch Bend: missing from the midiformat userguide
When I edit pitchbend data in midiformat->mpeformat (inlet 1) it usually registers on the MIDI Tab of the Wavetable Instrument, under 'PB'. In an effort to affect the MPE 'Note PB', the only time i could get that to respond was when editing pitchbend in one of the specific Note Channel Inputs, ie input 2, 3, 4. Why is this? Just trying to understand.
3) How do you send out MPE Slide data?
for midi standards, rather read midi specs.
has nothing to do with mpe , but base understanding of raw midi messages.
poly pressure is the only "per note" message that midi channel has to offer.
mpe does that for all messages on per channel basis,
basic mpe is nothing else then well organised midi poly with 16 channels.
