You can use the knobs to control just about anything on any screen. One of the latest updates allows you to touch the knob so you can see what you’re changing/effecting.
I’ve been giving some thought to the new versus old MPCs. The new ones have more knobs i.e. 4 knobs versus 1 slider. You can configure those knobs to control just about anything at a project level (macros) so there’s some more control for sure with the new ones.
But the 2000xl had some magic to its simplicity. I had one around the same time 99 to 05 maybe 06.
With that said, I borrowed a friends XL recently and was like, “damn, this thing is a pain in the ass to do XYZ in this day and age”
