Yes of course! But it's exactly THOSE supposedly played 'keyboard parts' that are only FAKED in which I so distain. Utilizing SMFs, sequences, or auto accompaniment is fine, but when a performer insists on FAKING his/her playing itself (melody line) then this shouldn't be billed as a live concert, but entertainment for entertainment sake only, and perhaps should be more aptly booked as a comedy, mime, karoake, or lip sycing act, not a LIVE music concert. - Scott
