I think the analogue hype isn’t over yet. See what Behringer announces (okay let’s wait, what will be realized, but Model-D and Neutrino are real, after all). So will we see “new” digital concepts in the near future? Don’t know.
I think, the most innovative place for electronic music devices are the Eurorack modular world and crowd-funding projects … plug-ins, or apps for iPad.
Maybe we will have a similar story for synths as we had for computers … starting with huge expensive main-frames, changing to workstations, followed by personal computers, ending with small units like phones, tablets etc.
The analogy could be, starting with huge modular all-inclusive synth behemoths, ending with small affordable boxes, which are specialised for this and that task.
Maybe it’s more efficient to buy a Blofeld (wavetables), a GR-1 (granular), a NF-1 (formant), or some modal-filter bank and to forgo the all in one uber-synth?
