Hi Italophile,
regarding the encoders issue, you're totally right, and as TerryM said, we'll consider this one on a future update. Unfortunately,at the time of writing, i can't tell when it will be released.
About the pads, yes, the logic would be to have the lowest note on pad 1 and the highest on pad 16. But during development, we had to consider that in the case of finger drumming, like you would do on an MPC or other similar devices, the kick pad is located on bottom left part (pad 13 on the keylab mkii). As it was an issue for many people, and as the pads rows were already manufactured, we had no choice but inverting this logic, in order to respect "finger drumming convention"
Hope this is clearer for you then.
Thanks,
best regards,
