Oh I know that someone has to be the first, but it seems to be me, a lot. Cherry Audio Memorymode for instance......massively popular memorymoog clone. I was sure it would be here as it was released weeks ago, but there was no sign of it. Seems every time I buy a new thing, I have to add it myself. I added 4 just today. Blue Cat Late Replies, A.A.S. Multiphonics CV-1 ( which is the modular synth I was enquiring about ), Cherry Audio Memorymode, and Zplane Peel.
As for the modular category, they aren't just synths, as i'm sure you know you can make drum machines, samplers, effects etc...in them as well, and there are enough of them now to justify having their own category, because they are quite different. You got cherry audio voltage, softube modular, a.a.s. multiphonics cv-1, reaktor, and VCV will be releasing a vst version before the end of the year, plus others I can't recall right now. If you want to find a modular environment, it's a very specific thing, just as the need for a delay category is different to a reverb, even though a reverb is technically a lot of delays. we also have separate categories for limiters and compressors, even though they are fundamentally the same thing with different ratios, so I don't think it's splitting hairs to have a category for a modular environment.
