I re-initialized my qs7 and now it doesnt sound the same. I never changed anything since i bought it. I always used it in multitimbral mode. The sounds are similar but I think the effects are different now. Could some please tell me what could account for this change in sound. (the pans are off, it sounds cheesy, some sounds react different to modulation wheel now) I think i didnt change anything but if i did what could it have been???
