Just made me realize outside of possibly Arturias emulations nobody has made a VSTi with a virtual patchbay, we got synths that have patch cables, but none that have like the Moog and Behringer style patchbays on the side. That would be cool. Alot cooler then a mod matrix.
Patchbay is great solution for analog average size semi-modular synths. So why we should limit ourself on digital space? How you're going to modulate modulation and adjust amount and set curve of one on patchbay? Althogh, patch cables with mod matrix would be not bad as well. When you do more or less complex patch it's easy to tangle and forget which goes where. But existing mod-matrix I'd improve a bit.
