My New Ketron SD90 will be delivered to me on Wednesday this week. I will post updates about the SD90 in this thread and try to answer any questions asked here about the SD90. I loaded up the SD90 with all 3 Gold Packages, the AMAMSONIC package, and added a 120 gig SSD drive to it. So to get started:
1. I will use the SD90 with my Roland A-800 Pro 61 key midi keyboard.
2. On gigs I will be using a single Bose L1 Compact speaker.
3. I will experiment with using all my song setups from my Ketron SD7 which I owned for about 3 years.
4. It will be interesting to see if the SD90 can be controlled using the buttons and sliders
on the A-800 Pro keyboard. (I don't know how to make this happen yet)

Stay tuned for my personal evaluation and experience with the SD90.
