Hi guitpic1,

I am glad that you are keeping your Casio PX560 - its keybed is very responsive and performs well with external modules such as the Ketron SD90.

Bachus mentioned in other threads that he plans to use his Kronos 88-key with a Ketron SD90 module some time next year.

I found that the keybed of the Casio PX560 works much better, more reliable than the Korg Kronos 2 88-key to drive the Ketron SD90 module. The keys of the Casio PX560 bounce back immediately, never missed any notes, which is great for controlling the SD90, whereas the RH3 keys of the Korg Kronos 2 88-key have delayed bounces, sometimes causing slipped / missed MIDI notes on the SD90 module. My 18-yea-old Yamaha S80 88-key has the same problem as the Kronos 2 with missing notes occasionally.

Thanks,
Paul
