I recently purchased the wk2 arranger module to use for recording song arrangements (light jazz) I could use when playing in public. My goal was to pre-record songs and play against them with my piano - not triggering the wk2 during live public performance - only during recording arrangements at home. HELP - did I buy the wrong thing or what should I have gotten - just can't see any way to use this for bringing my arrangements up quickly during a performance.
