This is a good idea, following on your own suggestion at New feature: Chord mode like the OXI. The full pad only for notes might be overkill for most people and scales. We could have two regions of 8x8 pads, one for notes and one for pads. That would also put developers and users in a very familiar territory, given that 8x8 pads are commonplace for notes and chords (Medusa, Launchpad, etc).
