Hi Squeak,
had the QY10,QY20 & the QY700 ( not the QY100,though). At the time , early to to late 90's I thought they were wonderful. I just to take the QY10/20 with me everywhere, they were that tiny. I thought of them more as a sketch pad for ideas . They're not a realtime arranger.
As much as I loved the QY700 ( bigger brother, much more expensive) for it's sequencing capabilities etc, I was not overly wrapped in it's sounds. At that stage ( late 90's)I had a Roland G800 & a Technics KN5000. Personally I preferred the sounds of those 2 keyboards.

Don't know if you're planning on just using it at home, and if you have a computer anywhere near your keyboard, but there is quite an array of software out there. If you really want to use psr styles why not consider something like OMB. You can tweak the styles and use the Casio for the soundsource or possibly consider getting something like xg soundfonts.

My laptop /omb/soundfonts/digital piano, has replaced my qy's of the 90's plus my 9000pro. VA7, & kn7000. Hubby's never been happier. Plus he doesn't notice an additional piece of software here or there.

best wishes
Rikki
