I like using a control mode knob to manually set aftertouch, sorta makes it like having two mod wheels on my Bass Station. It would be super rad if the pads could send aftertouch information as well, both real time so you could apply aftertouch to a sequence at any time and also a latching aftertouch mode with custom off/on midi values (being able to quickly latch from 0 to 127 on aftertouch's value could be useful to have a sort of "on-the-fly" variation on a synth sound)!
While I'm here... MCC has a sequence length knob for SEQ1 and SEQ2, but not for DRUM! Not a huge issue, but it was a tiny inconvenience for a moment there.
