mpk49… have one… have a love/hate relationship with it. The feel of the keys is a bit different, but works fine for me. I tried a few other controllers at the time when I was shopping and this was the best one I tried at the time.
The illuminated pitchbend and mod wheel are cool looking and great ergonomically.
Do not buy it expecting the pads to be useful. I should repeat that last for emphasis.
Not a big fan of the patch selection: twist a knob then push it down. Kind of asking for accidental patch changes when you push down.
I actually tried the homebrew adhesive cork under the pads. Totally didn’t work for me, pulled it back out. The faders and knobs are decent. The switches can only be used for on/off, so don’t expect to send a specific value other than on or off (0/127 or 0/1 I forget now).
With the OT, it should be servicable. I transpose the kb so that playing samples chromatically works. Haven’t mapped the other controls too much yet, but I should.
I have had it for a few years and it has held up well. Not built like a tank, but decent enough.
For $180 if you like the feel, I’d say go for it.
