In regard to the Ketron SD7. I have owned it for a while now and the styles and instruments are very good. It still has problems such as "freezing", failing to change from one preset to another and vol. differences. All keyboards have problems when first out
but Ketron is much too slow in corrected their problems.

I have a Tyros 5 that really fits the bill. I love it. Lloyd
Don got rid of his Ketron SD7 for the above reasons.
