My MIDI keyboard (Korg microKEY) just arrived last Friday, and dear God it's amazing. Wonderfully simple, just how I wanted it - 3 octaves, pitch/modulation knob, up/down octave transpose tool (giving me access to the full range of notes) and it even has 2 USB ports at the side in case I'm out of USB ports and want to add more USB devices (which already came in handy because I'm now using one of those ports for my iLok key).
I was planning on getting controllers with it too, but thought against it because the modulation knob does the job fine and I'll usually be automating one parameter at a time anyway. It's really fun to just go to one of your project files, mute the lead instrument and play it with the keyboard instead. It's also fun to doodle melodies with my left hand while browsing the internet with my right hand on the mouse. It's not the first time I absentmindedly let my left hand play random melodies while I'm on the Internet and I suddenly come up with an awesome melody, and I've only had this keyboard for three days.
Best 80 euros I've spent in a long while.
