Gregori Klosman's midi keyboard controller in the studio is the M-Audio Keystation 61es MIDI Controller. "This is really basic. There are no knobs or faders. I like the touch, though. For me - because I used to play piano - I need to feel that kind of piano vibe." Source article [here](http://www.musicradar.com/us/news/tech/in-pictures-gregori-klosmans-paris-studio-600687/5).more
This keyboard is amazing. I love its mackie transport controls. This controller is simple and fits on a desk between your computer keyboard and monitor very well as it is a compact unit. If your not someone who needs all the knobs and your more into controllers for just keys, this is what I recommend.
Bought it used and works as it should be. The problem for my configuration is (PC, Win7 64x, Reaper DAW) is that after coming back from sleep it doesnt recognize the device, so I have to do a routine of Unlinking the device, On/Off the device, and back on. Other than that the keys feel quite good for being semi weighted, I even made a DIY sustain pedal which works good.
I basically picked this Midi Controller for its simplistic form factor. It gives me what I need without the un-needed extras. If your in the market for a grear Midi Keyboard without breaking the bank, this is your best bet.
I've been using this keyboard for about 4 years and it's still serving me well. The keys have held up great. About a year after I got the keyboard the volume control starting acting up, sending data while not being moved. About a year after that the pitch bend started doing the same thing. It may just need cleaning, I suppose. In my workflow I only use the keys and mod wheel (which still seems fine), so I just have the pitch bend and volume messages filtered out.
I use the Keystation for most of my live keyboard needs, mostly because it runs so well with Logic Pro X. It's large enough so I can play most piano parts, yet small enough where it doesn't take up too much room on smaller stages.
I love this keyboard it feels semi weighted, working with a almost full sized keyboard like this makes working in the studio feel more authentic, instead of clicking in all the notes in a sequencer/piano roll, it feels more like im making music and not some highschool project. Imho
