I can get if i press Fx but i only have 3 to choose from. Also my gain control on the back does,nt do nothing. Maybe there is a internal valume control. I bought this used and i have to get the info from downloaded manual. Also maybe someone can tell me where to go for the 3.1 upgrade i went to korgpa.com but it does,nt show me the down load .
Any help would be appreciated. Thanks
