I think Frames is a really interesting idea and a brilliant module in many ways, but I ended up selling mine and putting a Maths in its spot with no regrets. I could see Frames being super useful if you are using it as a preset morpher, sequencer of sorts, or some other form of predictable, controllable, predetermined modulation, but what I wanted instead as a sort of “modulation centerpiece” was something that was able to output things different from those which I put in, or rather different from what I might think of myself - Frames doesn’t really do well (in my experience) in a generative/self-patching/experimental context, which is often what I want my modular for.
It also wasn’t designed for those things, but I ended up wanting something with a use that could transform as a patch progresses, whereas Frames needs its use to be predetermined, at least to a degree, by its nature.
I don’t have a Cold Mac, but it seems like it’d fit the same sort of goal of a ‘macro’ control, but with more potential for self-patching and more complex interplay between signals. I also think that Maths is deserving of its reputation…it can do so many different things (like the DUSG it is based on) but the mixing/offset/logic options in the middle, and the way they interact with the function generators themselves, is really special and versatile.
I suppose what would be a good addition for you might depend on whether you want to add things that are perhaps more prone to happy accidents (which I think Cold Mac and Maths would fit in with), or do you want another versatile module that is more for surgical precision?
