What I find really interesting about your experiences zolhof and jeffc is that it seems to confirm a pet theory I've had for a long time that often the big advantage of hardware isn't sonic. There's still a bit of snobbery around that looks down on the sound of soft synths, and while yes some sound better than others a quality product like Omni has always sounded very good
Hardware is pretty much just about the buttons, but that's not to play it down. The buttons are amazing, you work differently with them. That's a nice thing about those 1,000 presets incidentally, they could have been designed just using Omni but you'd have got different results.
These conversations often come back to the same thing - the lack of a decent hardware controller, laid out actually like a synth (no current controller comes close to cutting it imo). It seems kinda nuts to blow a few grand on some of these models when you don't even need to plug in the audio jacks.
