I have to admit, I used a Casio Wk3200 on stage (for the piano and organ sounds, and as a temporary controller for Midjay) for a few nights. I must also admit I used silver masking tape to cover the name. In the words of Jimmy Reed: Shame, shame on me.
I did THINK about leaving the name showing and telling everybody that the arranger they heard was the Casio. But that would have be cruel.
