As you may know, I recently purchased a Ketron SD1. I do really enjoy the 76 keys. Also, my "fans" who regularly come to hear me have commented on the "new" sound, and ask what I've done to make it better.
Even though the SD1 has been out several years, and is a little behind the times in data transfer, it is also far ahead of its time in many other departments, including sounds, personalization capabilities and even live play.
The vocal inputs work great, and the vocal harmonizer is far superior to the Tyros/PSRs.
Main drawbacks for me are the smaller buttons and the way some of them are placed. However, with the help of the 6-switch foot control, I am finding it quite comfortable to play live.
My point is, when looking for a great-sounding 76-key arranger, don't overlook the SD1.
Support? How many companies come out with a new operating system, several years after introducing the keyboard, that in effect makes it almost new. That's what Ketron did. The new OS contains many new features, styles, sounds, etc., all at no cost.
