It would be nice to see somewhere (preferably near the pitch slider) the current pitch range. This would allow to use and change the control value of "rateRange" from any controller and see the change of pitch range reflected in the GUI, adding functionality like having the Denon DN-D4500 model.
Explained in a review found on the web:
"...The DN-D4500 two pitch sliders (one for each deck) are pretty much the full height of the 2U high control panel, and confirm to the usual layout of Zero in the middle, slide down for faster, slide up for slower. How fast and how slow? Again this is adjustable to the DJ's preference and musical needs, using a 2 second press of the button marked "Key Adjust/Pitch Range". The pitch range is selectable between +/-4% for easy precision where the tracks you're mixing are close in BPM terms, 10% (a happy medium), 16% (for those tracks where their BPMs differ a lot, also 24%, and even 50% and 100% (The only way to play the Birdie Song, or Opps upside your head)."
