[sgroup] Roland S-10 problem

Hello all, i am a new roland user and i have a problem, maybe someone can help... i recently bought an used S-10; unfortunately when i take a sample i will only get 14 semitones higher notes (then it plays the correct note but one octave lower...) and not 21 as indicated on the manual. this is annoying because also when playing existing samples i get "lower octave" notes for the last 3 to 4 keys at the end of the keyboard.... any idea about what could be broken? thanks in advance for any help and long live roland :) Gian -- GMX DSL: Internet-, Telefon- und Handy-Flat ab 19,99 EUR/mtl.
