Deane, I agree that the Ketron sound set is great, but TBH - I never thought the instruments I had prior to the SD7 DIDN'T sound great. The drums on the PA4x always had a live punch to them, and the other sounds were very realistic. I'm sure I'm where I need to be right now, and that's all I care to focus on at the moment. I've always had more than enough work to justify my gear selections, but now that I had more gear than work ... I shall be more mindful of how often I make changes. I'm excited to get to know the new SD60 with it's turbo engine (dual core) ... by the time it arrives, I'll be ready to tackle anything.
