I’m not so much worried about the technology, I’ve been all in on that. It’s about the ‘music’ that that particular type of technology produces, and its live application. Go listen to any synth demos, then try to figure out whether there’s even ONE venue in your area that plays that kind of music live...
I sure as hell can’t!
On the positive side, I think that arrangers have approached close to their zenith. Without actually needing to have any real grasp of the underlying technology, never has it been so easy to grab a one finger chord, create a quick chord sequence, and jam over a backing that is harder and harder to distinguish from the real thing...
