I like it because it has knobs that seem to be able to read the current settings (audio, pan, etc) as opposed to the Korg Mini Kontrol that I have that works but you have to "capture" the level control. I have not bought it yet but was wondering if anybody else is using it or something similar. The price range is in my range.
