Interesting about the ADDAC filter, that's another company that seems like they have really useful and nicely made modules that I don't see a lot of chit-chat about, really. I was briefly considering their Stinggy Filter, but sort of put that low on the considerations list ... I forget why, maybe not enough CV options or maybe something about the demo that left me a bit meh. But I had their Sum & Difference mixer for a few weeks and it was pretty cool, really solidly made and interesting -- but again, very little CV control over anything as I recall.
Still something about ADDAC appeals to me, though, but they tend to be a little pricey for me at the moment. I did actually recently order their 4-Voice Cluster and their expression pedal adapter, but I don't have them yet. Curious how that will go. The 4-Voice Cluster doesn't seem hugely popular, and I could see from the demo how it could be a bit one-note as a sound source, but there's something about the character of its sound that really appealed to me and feel I'd like to work with, and the price was right at the time I ordered.
