Just got sr18 and trying to copy from one sub pattern (ie preset 00a to user 00a) but while I can copy full preset pattern (a,b & fills) to a user pattern, I cant copy to a specific sub pattern - I press copy, select a user pattern destination but when I press a or b no response. Just wondering if its a prob with my machine (bought it second hand) or I'm missing a trick. Any help appreciated.
