The fader, knobs, and modulation wheels are very smooth and precise, and the keys have good velocity tracking. One of the best things about this keyboard is that you can use it as a MIDI I/O device without a USB, and for the price I got it, it's a steal!
Best budget starter MIDI keyboard that is great for simple MIDI mapping and MIDI data entry. I use the Oxygen 8 in my live set with my electronic band and I find it extremely articulate as a midi controller. The array of knobs gives you the opportunity to MIDI map essential parameters within ableton to the knobs, making it easier to adjust a plugins parameters live.
