My favorites are Make Noise Optomix, Mutable Streams, and Mutable Blinds. I don’t have a Mutable Veils, but I hear that it’s excellent.
Blinds can act as a four channel mixer with per-channel attenuversion and offset. Yes, you can add offset to a signal. You plug the signal into the CV input instead of the main input. It can act as a ring modulator, as negative CV will phase invert the signal. Veils also acts as a 4-channel mixer and adds the ability to change the response curve of the VCA.
Streams should be way more popular. You can treat either channel like a regular LPG, a regular LPF, or a regular VCA. You can also use it to generate vactrol-like CV responses (the inputs are normalled to an offset, so you can just hit the EXCITE input and get a rubbery decay envelope on the output). Because the vactrol is simulated, you can modify its response. You can also use it as a stereo compressor, envelope follower, frequency tracker, etc. It’s amazingly powerful, and sits right next to my output. My only issue with it is that the outputs aren’t mixed together. You’ll need to pair it with a small mixer if you want it to behave like an Optomix. BTW, the VCA and LPF on it are analog. They’re just controlled by digital envelopes. It sounds great.
Finally, Optomix is just my LPG workhorse. It’s a perfect module. I haven’t updated to the newer model as there’s nothing I dislike about the Optomix.
