I’m sorry for all the frustration. I’m still really happy with mine, I hope yours is a fluke and I’m lucky with the keyboard; that it doesn’t fail on my next laptop or something.
I also considered the MPK249 and thought it felt “decent” if not great, keybed-wise. The Novation SL Mk3 was better and looks like it has great features. But both of them have eight faders which I just can’t get past, if I get a knobby controller keyboard I need at least 9 for drawbars. It frustrates me that manufacturers seem to often disregard this as the cost of adding a single faders would be marginal.
I like and own the Nektar Panorama P4 but it’s decidedly more plasticky in construction. I ended up keeping it at home in the studio but I gigged it for a while. It has more directly available controls than the Arturia (16 pots, 9 faders plus one motorized fader) but no one button fader bank switching like the Keylab.
One fader started malfunctioning and while I got it repaired I got the Keylab. It has been perfectly fine since.
