Hello, I'm using the Sensel Morph to control Aalto and using MPE Midi. I'm using SuperCollider as a VST Host so I can control exactly how the MIDI data is translated from the Morph going into Aalto. I'd like to directly use the Channel Pressure/Channel Aftertouch to control the volume of each Aalto voice individually. What's the recommended way to accomplish this? So far I'm having trouble getting the Morph's Channel Aftertouch touch MIDI MPE events to be seen by Aalto. Do I need to combine MIDI messages so that Aalto sees them as part of the After key input?
I can get individual note pressure to work when I use standard MIDI and polytouch, but then I lose the individual X/Y controls for each note. When I use MIDI MPE, I can't get the channel aftertouch pressure MIDI data to show up in Aalto's after key input. Is there a way to get the best of both worlds with the Morph and Aalto?
There's at least one tutorial online— does this help?

It sounds like you are doing things right. When Aalto is set to MPE mode, the channel aftertouch should come out of the "after" input to the patcher. Through the patcher, each voice gets its own aftertouch data depending on the channel.
You do need to set "MPE MIDI" explicitly in Aalto using the "Input Protocol" choice in the settings (gear) menu.
