Don’t mean to take away from the feature request. But since we’ve had this discussion a couple of times, and arrived at various approaches to realize this with Scaler as is, it would be helpful for the dev team to know more details about what you have in mind with supporting 8x8 MIDI pad controllers.
I don’t find it difficult to map my Maschine Jam 8x8 to Scaler pads, not sure about the Ableton Push or Novation Launchpads, but the Maschine Jam is pretty configurable as to its pads. Once you have a template matching the Scaler section C chord pads, it works pretty well. Not sure what would be useful on the Scaler side to accomodate a MIDI controller?
