Casio certainly has the clout to make an awesome TOTL arranger, if they wished.

Back in the day, they briefly got into the pro keyboard market...I had a couple of their instruments, a CZ-1, and a VZ-1, Phase Distortion (or PD) digital synthesizers, and an FZ-1 sampler...all were very competitively priced, and sounded incredible. Their CZ-5000 PD synth sported a pair of SZ-1 digital sequencers...and this was 1985!

These instruments were all pro quality, both in terms of sound and build construction.

They also had one of the first velocity sensitive arranger keyboards (1984), the CT-6000.

There was a strong rumor going around only a year or so ago that they were planning on a mid-range or perhaps a top of the line, arranger, but so far nothing has materialized, but, I wouldn't count them out...not for a second.
