Great suggestions! I love the Z-DSP. And all of MakeNoise’s stuff. Love that the Z-DSP is open source, especially. (Of course, the selling of all those extra cartridges is a little tacky - Like pokemon for eurorack)
I suppose, based on experience, SSL hacks into chips in really unique ways that sound and behave differently. Neither of these three modules (SSL, Tiptop or MN) are better than one another, and it’s nice to have so many choices. It’s not just the control voltage access but also the fidelity, or noise suppression, response of CV, all that stuff, and I like that SSL’s modules tend to have weird glitches included.
Being “one of the oddest” allows for other “oddest” ones, too.
I’d include the Knas Moisturizer and the Metasonix R-56 to your list.
