Boy Don do I know the feeling. There has been a delay from Italy in getting my new SD90 ready to ship to me - I really loaded it up and increased the SSD size. So, I have been left with my Yamaha S975 for gigs since you got my SD7. I have spent hours each day working with it but it is paying off and now I don't want to get rid of it.

Keep after it - the SD7 WILL be worth your effort.
My SD90 should ship this coming week and I will post my review when appropriate.
