Hey Squeak, i went to a keyboard store yesterday with my dad as he was keen to buy a Casio CTK 7000 to add to his studio. He had the cash to buy it and was about 95% going to get it but ended up leaving it...
for the price YES its feature packed and has some great sounds. but it is still very far behind the game in my opinion. I Too believe the MZ 2000 was way ahead...
browsing through each of the sound categories we were very unimpressed. The Stereo Grand Piano was probably the most impressive voice and thats after you add a bit of reverb to it...
The styles were not very great either. with only 2 variations, no style part select/mute buttons, its not versatile enough for live play as you would get on most other MOTL boards.
I see the CTK 6000/7500 as a low end beginners board with some good quality sounds than the rest of the bunch at its price range.
I would go a GW8 or Prelude any day over the new CTK series...
Nick
