I would say, definitely yes … and there will be more. Maybe some of them are not as “new”, as I think, but at least they are different from the most often used approaches or they may be new combinations of techniques.
Just let’s look to all those west-coast style approaches to form sound that have been shown for eurorack and are keeping up to come. If somebody comes up with a new kind of VCO, or effect, be it analogue or digital, we might get exactly those new tools to experiment with …
Two examples here:
There is an interesting plug-in available since last week, or so, called Mushroom generator (by Soundmote)
It seems to be an interesting “combination” of techniques to form and shape waveforms, which is different from the usual single wave-shapers, wave-folders etc… I have played with it for some hours … and … yes … there is something “different” and “interesting”.
Or let’s check out machines like the Lyra-8 by Soma Laboratory. Created by a guy with a kind of philosophical approach to organic …
We have only to give those techniques a try. The Lyra-8 is so unconventional IMO that I guess that everybody trying to play it, will come up with new ideas …
