Novation Launchkey 37 MK4

Very nice midi keyboard, easily accessible features, but be aware, it has lots of amazing features but they only work with Ableton (step-sequencer and other). I did not know this before buying, so I returned it and bought the Native Instruments Kontrol 49 instead, since I don't use Ableton, but I do use Kontakt. I felt the 37 keys on Novation Launchkey was also not enough for testing and sound production, even though I do not know how to play with both hands. 49 keys are better for testing sounds imho. Also I didn't like the buttons (not pads, but the buttons) on Launchkey because they are indented and under too much silicone, I like them more on NI Kontrol because they are not indented, they have a more noticeable "click" so you know when you pressed them. The actual keys are a bit nicer on NI Kontrol also, and it's cheaper. If you use Ableton this is a great buy, otherwise not so much.
