I definitely lament the demise of the rack synth. TBH, I am surprised, with the modern economy, that these aren't MORE popular now than ever. I would definitely be interested in a rack Kronos, or even just a rack Hammond or more modern Nord.

Admittedly, my G70 isn't the ideal controller, as the sliders and knobs can't be programmed to send whatever you want (but my K2500 can), but it sure beats schlepping an MS! Actually, just kidding, Fran..! As an addition to a decent arranger, the MS is amazing. It's just a shame Dom could never turn it into an acceptable arranger...

But the new Integra7 module from Roland, for maybe a Tyros user or PA3X owner would add in all the Roland flava with minimal extra gear to haul. But truth is, as I don't use MP3's, my G70 still does all the job I REALLY need. Sure, I'd love some extra stuff, but it's still doing the job, and has paid for itself (both of them, really!) so many times over, I can't complain.

Studio-wise, though, I am pretty well set up. A Roland, a Korg and a Kurzweil pretty much cover it all, and VSTi's cover the rest. Life is good!
