AJ...I DID play the SD1 and found it to be fast enough to navigate the instrument patches readily (I'm assuming it's as easy to pull up a dance style). The posting above from Craig caused me to question that. As far as I remember, I found no difficulty in that respect.

I should add, my needs are unique. I have all music in my head (spent many years memorizing). I will think nothing of playing a 15 minute medley and weaving through different sounds and styles and types of songs. This is why fast "navigation" of a keyboard is essential, though not my only need. I tend to show off a keyboard's capabilities (to an audience) as well as entertain them with good music. No response needed as I'm still pouring through Ketron brochures and reading comments on the Web from Ketron users/players. So far I am hearing nothing but praise about Ketron and am looking forward to owning one ASAP.
