This keyboard also deserves to be mentioned!
It is my MIDI controller keyboard that I've been using the last three years or so.
It's nothing fancy, just 4 octaves and 8 knobs and some buttons. I rarely use the knobs, never use the buttons. The knobs are good sometimes when programming VST instruments but I usually don't bother mapping them.
Since I got my rack with the Matrix 1000's up I naturally control them using this keyboard as well.
It juuust fits on the table in front of my computer keyboard.
One day when I have more room, I think I might get a bigger keyboard but this one is doing excellent for now.
