Got my Xaoc Koszalin. It's beautifully weird. Aside from the obvious psychedlic swirly modulation and making harmonic things inharmonic, it pings pretty nicely (not with predictable/controllable pitch though) and the simultaneous up/down outputs and stereo make it great for self-patching. And the TZFM input adds quite a twist.
Patch into the right input, right up output into some effect, effect output into left input, monitor the left down output... the shift up/down is pretty subtle but if you modulate it you can get some cool tape warble among other things. Or mix two opposite outputs to turn it into ring modulation... which is cool if you do it in stereo and almost merge them to center.
It pairs well with Odessa. Use Tension to detune the partials and then try to line them back up again with Koszalin -- usually you fail but you might create some cool chords/clusters/drones in the process.
It's thru-zero, so if you lower a frequency band below zero it doesn't just silence (like the Freq Shift device in Bitwig) but reflects around 0Hz. That gives a whole different range of inharmonic tones to play with.
It lacks a wet/dry control but given the self-patching possibilities, sometimes it's better to mix that yourself anyway. As far as barberpole modulation goes, the feedback serves a similar but more variable role to a wet/dry mix anyway.
Also yesterday I got my first build progress photo of the Miezo 18 I ordered -- the body carved and drilled and the fretboard assembled. The two woods match very nicely. I expect the rest of the build probably won't take long...
