The unit has 1.16 firmware but the aftertouch sensitivity setting isn't there on the user screen which I thought may help (I can see it in Live so maybe it just isn't implemented for Bitwig). Googling this brought up very little so I'm wondering is it faulty or is it just a technique thing.
If this happens also in Live I would say that the device is faulty.
I'm a bit puzzled tbh, I was finding some severe inconsistencies in the pads in terms of pressure plus it was only sending channel pressure. So I unplugged and restarted Bitwig and it was back to poly pressure but over sensitive compared to previously and pretty much like the quNexus.
So I went back into Live and saw that the Aftertouch Threshold is set to 80 by default which is high but definitely makes it much more useable. However Live once again changed it to Channel Pressure presumably because Live doesn't understand Poly Pressure, and so it's impossible to know if it's even relevant to poly pressure at all and the only way to restore Poly Pressure is to switch off Push after having Live open. Is there any way you could add this option to your framework?
This is the blurb on Ableton:
"How does this parameter work?
The Aftertouch Threshold determines at which point Push will actually send Aftertouch data to Live. A value of zero means that Aftertouch is generated all the time (with this setting, Push behaves exactly as it did in Live versions prior to 9.2).
A setting of 127 impies that no Aftertouch will be generated at all.
The actual range of MIDI values sent to Live will be scaled up to match the standard MIDI resolution: for example, a setting of 80 means that the 47 available values (127-80) will be scaled up to send Aftertouch values from zero to 127."
