Ways to use aftertouch with instrument layers?

Using Zynthian

I’ve got a MIDI controller that has aftertouch and I’m trying to figure out a way to make it useful with my instrument layers. So far I’ve understood that you can use the webconfig MIDI filter to map Channel Pressure to a CC and then use the MIDI learn to assign that CC to a desired parameter (I’m yet to test this, but at least in theory it should work). This involves mapping the CC to a useful parameter for each instrument layer.

Then there’s the another thought I had in mind: is there a way to make aftertouch control a certain specified parameter globally (for example pitch bend/expression/volume), as follows:

  1. I select an instrument layer
  2. I play notes from my controller. Applying aftertouch applies pitch bend/expression/raises the volume according to a range (how could I set the range - by using some of the MIDI filters?). Important is that releasing the aftertouch should return the parameter value to a certain default value I’ve specified.
  3. Could this behaviour somehow made as “universal default” - so that, by default, applying channel pressure to any instrument layer behaves as described in 1 and 2. Could this be possible by creating a MIDI layer that feeds the instrument layers (and maybe uses MIDI filter to keep the CC range in check)?

Sorry if my message is unclear. I tried my best to describe what I would like to achieve :smiley:

It’s the new Roli Piano that actually even has polyphonic aftertouch and MPE. I found aftertouch usually needs to be mapped to something tro be useful, but the per key ptch bend that this controller also has, works well.
