AJ, I am a current Vega owner, and I also own a Yamaha DX7, and future Korg Prophecy also... But I would like to make a statement on general features that should be expandable and add ons and future expectations/suggestions...
Well, I dont expect the keyboards to be perfect, Since ketron doesnt have such a large name as say Yamaha or Korg, yet I think that what was on the X1 was just great. The keys are very nice, not to mention so is the sampling option... Also Please understand, that many many people get frustration with that fact that with the vega, you cannot compile your own sounds with the Flash card... Sometimes, you are stuck with sounds that you are never going to do, yet you buy the flash card because you want the best options for your keyboards. Rather than release flash cards, release sounds that one can put into the flash card manually. And customise it they way they would like... For example, i would seriously love to sample my VST synths and sounds, and use on my Vega... That would definitely make the Vega or any other keyboard much stronger... I also suggest More expansion room for Vega and higher future models... as 8mb does not compare to any competitors, such as Korg/Roland/Yamaha... For example, I bought the vega with the harddrive expecting to be able to save samples on there (which is my fault technically), use of the Harddrive for samples, or larger Ram upgrades would be nice, Even 32mb would be awesome... but with the money I spent on the vega I could have bought a Nice Triton (i spent $2,200 USD in the end)... Another option?, well, It wouldnt just be nice to edit sounds, but also to manually create sounds, in other words, Synthesize... I've heard beautiful sounds made through Frequency Modulation, and thats technology from the 80s

I know because I like to program FM synthesis... But a nice Analog/Digital synthesizer inside the keyboard would truly put it ontop of Competition... I mean, if I had a moss board in my Vega, I wouldnt bother to get a Korg Prophecy

I would also like to mention that, The Vega samples, they are truly great samples, yet there could still be a bit better work on Multisampling from this company,I truly love Ketron, but the fact that the limited expansion at the current moment, (at least with vega) I would say the only I am Satisfied, but not with the money i spent
