I used to use a Casio CZ-1 that sat on the stand above the Yamaha DX-5 I was also using.

One of my Yamaha buddies came to the gig, and on break, he remarked how great the DX-5 sounded on the last tune.

I took a perverse delight in telling him the instrument he heard was the CZ-1, which I was playing from the DX-5's keyboard through MIDI.

Casio FZ-1 samplers are collectors items, and I just sold a mint VZ-1 a few months ago for a pretty darn good price.

The day I start being concerned about the logo on my keyboard in relation to what someone else thinks, will never arrive. It has never made one bit of difference to me in all the years I've been playing.
