I've been working on some lead sounds on my PowerRack for live use and I ran into a little problem. I use a Behringer fcb1010 with Uno4Kemper 1.3 chip. I programmed a Wha in some profiles and although everything works fine, the Wha sort of stops working after I reach the D note on the high E-string in 10th position. Everything after that sounds normal. I can hear a slight shift in tone, but no quack whatsoever. Whereas on the low strings and up to the high D is sounds absolutely great. I've tinkered around with it, used different wha's, adjusted parameters but the sound doesn't improve. I must admit I'm not a technical person and mostly wing it using my ears. So I thought I'd try my luck here and see what people's experiences with the onboard Wha's are and maybe get some tips along the way. :) Thanks in advance. My parameters are pretty much default I think. I use a modified Fischer Xtacy 4 profile for lead with a CryBaby Wha for instance. My settings are: Manual 3.0 Peak 6.5 Pedal Range +26% Peak Range -25% Pedal Mode bypass@stop Mix 100% Ducking 0.0 Volume 0.0
