Synthtopia just carriedthe press release
I take this to mean that if a developer of a soft synth wanted, their plugin could now accept MIDI 2.0 data streams using the new developer bits from Steinberg. This is good, now there is a standard way for soft synths to take input.
It seems to me that the real innovation needed is on the hardware end, however. Part of what makes analog instruments so expressive is that there's a whole bunch of things all interacting at once in complex ways. There's no reason this couldn't be the case with high-speed sensors, but it just hasn't been the case so far. Osmose is the best hope so far for a keyboard based controller, though the Continuum is clearly "there already" for fine sensitivity in an "arbitrary controller".
Grid-based controllers have crossed over into a physical interface enough people are willing to learn. There are virtuoso finger-drummers, and I've seen stage performances where drum grooves that a human could play on a kit were instead performed by someone on an MPC/Ableton Push type controller.
It is such a catch-22. A new digital instrument needs to be rewarding enough to practice and master, and not at risk of disappearing before that occurs. It is apparently very hard to get this right, judging from the dearth of high-quality controllers. We just don't have great wind controllers that cost like a pro saxophone and offer similar expressiveness. We don't have superb bowed controllers, etc.
So, I guess I'm happy to see the software side - it is always going to be first. But I really want to see innovation on the hardware side - specifically instruments that put out nuanced, complex data streams. We have great synths with massive mod matrices - we need rich flows of data to drive them to really get at their potential. This a "gestalt" thing that the CS-80 got right. But some one will get it. I hope many do.
