MPE data reading, Aftertouch...?

jupe

Question?
Does anyone know how to read Channel Aftertouch data? Message.getChannelAfterTouchValue() - not found in HISE-script?

**

Reading MPE data experiments
Here is few of my experiments to see what data Sensel Morph is sending in MPE mode (and a few AKAI MPK249 nonMPE devices outputs) and how to read it in HISE to later do some processing.

I'm using Linux (Mint Cinnamon 20.1), so that may or may not pose some random problems.

Reading MPE data summary
Press, z, aftertouch, pressure,... NotOK???????? see Experiment 3 and 7
Glide, x, pitchbend, pitch, note bend, horizontal,... OK! see Experiment 2
Slide, y, CC74, vertical,... OK! see Experiment 4
Stroke, velocity,... OK! see Experiment 8
Lift, release velocity,... OK! see Experiment 8

Experiment 1 CC numbers sent in Sensel Morphs MPE mode

function onController()
{ 
/* 
Moving/pressing/sliding finger on my MPE keyboard keys 
*/ 
Console.print(Message.getControllerNumber()); 
}

Interface: 128

Interface: 128
Interface: 74
Interface: 129
Interface: 128
Interface: 74
Interface: 129
Interface: 128
Interface: 74

Conclusions:
CC #128 Pitchbend OK! see Experiment 2
CC #74 MPE slide CC#74 (maybe initial value = 0 better (than 63), then slide up ...127 or init value 127 slide down to 0?) see Experiment 4
CC #129 PolyAftertouch, not ChannelAftertouch? see Experiment 7

Experiment 2 Pitchbend

function onController()
{ 
/* 
Pressing my MPE keyboard key and sliding quickly right and left
(2^14 =16384/2=8192, 14 bits) 
*/ 

if (Message.getControllerNumber() == 128) // initial value 8192, glide right/left increases/decreases => PitchBend range -8192 - +8192, 14 bits
{ 
Console.print(Message.getControllerValue() - 8192); 
} 
}

before subtracting - 8192

Experiment 3 CC129 = PolyAftertouch see Experiment 7

function onController()
{ 
/* 
Pressing my MPE keyboard key with increasing/decreasing pressure
*/ 

if (Message.getControllerNumber() == 129) 

	{ 
	Console.print(Message.getControllerValue()); 
	} 
}

Press and slide up/down
initial contact 63
63 - 127 slide up
63 - 0 slide down
229 when key released

Conclusion: // initial value 64, slide up/down increases/decreases: 0 <= 64 <= 127, release value 229? confused - polyAT or ?

Interface: 229
Interface: 229
...
Interface: 229 - last one when pressure released

Conclusion:
Poly Aftertouch works as expected!
Channel Aftertouch does not!!!

function onNoteOn()
{ 
Console.print("Velocity: " + Message.getVelocity());

}

Interface: Release Velocity: 26
Interface: Velocity: 127
Interface: Release Velocity: 22
Interface: Velocity: 39
Interface: Release Velocity: 21
Interface: Velocity: 23 - hard to get velocities lower than that
Interface: Release Velocity: 23
Interface: Velocity: 48
Interface: Release Velocity: 29
Interface: Velocity: 49
Interface: Release Velocity: 20
Interface: Velocity: 47
