Might just be me, or perhaps just Glaze? But does this plugin show different areas of the instrument in KK or K7 like most instruments do - my keyboard is just yellow for the full range, no different keyswitches or anything.
On the Glaze walkthrough videos it looks like there are different ranges (e.g. the loops on C0/C1 and normal notes on C2 and up) for some patches such as Keeper (Amin) or Too Sunny (Cmin), the only patches with colour coded key ranges seem to be "I Can Wait" or "1200 Miles Away"
TIA
