After some more time with it, I'm really starting to love it! It's super easy to navigate and sounds really good.
What I really don't like is how the lowest notes on a 5 string won't trigger the filter properly, as the low not causes an unpredictable retrigger. This sucks when trying to get some upper octave synth lines going with a low bass line. When it works it sounds absolutely killer, but that's like 1 in 10. Again, were talking notes below D# on a low B. It seems to have more to do with note energy than something like cutting the highs.
There's some adjusting to get the poly and arp modes to work well, but those modes are likely worth the time. Once you lock in and figure out the knack they are really cool sounds.
The filter in dry mode I feel is not as wide ranging as a synth filter should be as far as wild settings - there feels like extra space on the knobs that could be tapered better to make tweaking easier. The resonance will not self oscillate, the envelope control feels like it should be able to sweep a wider range, and the sustain cut off in trigger mode are about all that I feel shorted on. Otherwise, and here is the important part, the filter is actually really easy to use, and for the most part sounds really good. It's not going to replace my Moog LPF, but on a compact board I would happily use it in place. The sensitivity needs some more time from me, testing drive and comps before it.
It's a really fun synth pedal, and doesn't require a whole lot of fighting or technique changes to make it sound good. I noticed using a pick can really help the volume of the notes start with a sharper edge, making quick likes have a harder attack. Fingers can add a subtle swell to the notes.
