Honestly sounds incredible, like a minimoog but with filters that don't quit or need bass compensation and also includes wave folding. Like it's got the feel of a minimoog but sounds like nothing else, the adsr on this feels a bit odd,like the release goes to 100 only 25 percent of a turn, but I think there is a firmware update for it. The low pass gate though is soo fantastic, the sounds you can make are wild. It sounds incredibly organic in Places. I've been dreaming of this synth for a long time, and it completely lives up to it.

The Good: Greatwave folding. Arguably the best analog wavefolding currently available (as of early 2025). Extensive patching options. Eurorack expandability

The Not So Good: Decay portions of the ADRS are way too logarithmic - only a small portion of the knob range is useful. Delay is mono even though the synth supports stereo outputs. Can be a bit clicky on fast transient, plucky sounds. LFOs are limited in upper frequency range.

The Maddening: The BIG YELLOW DYNAMICS knob. In order for it to do anything useful, it has to be turned all the way to the left. Turning it to values clockwise only lets the signal through without a key press (which can already be accomplished with the hold button). I suspect it becomes more useful depending on how you patch it, but in normalized mode, it's only good as a performative hold knob.

I really like this synth and I hope to see more semi-modular synths with keyboards just like this. It takes a different approach and I think it's great that Pittsburgh Modular is willing to experiment. I think it's quirks are what gives it character, but there are some things I've learned with it over the past month:

This isn't a synth that instantly sounds great in any hands. There is a learning curve. There are a lot of sweet spots that you need to familiarize yourself with.

The envelopes are weird because 90% of the time you're going to use the first 20% of the travel. But if you really want those longer times, you got it.

The first time I powered it up, there were a few times I thought something was wrong with it. But a combination of settings somewhere would put it out of usable territory.

The knobs are really enjoyable to play! They feel very nice. But just a heads up that they're so grippy, they get moved very easily. Even having a patch cable next to one is easy to pull an oscillator out of tune.

It's a great sounding synth. It's a modern sound, but not harsh. I love the filter! I really need to understand the VCA better because I'm struggling to see the benefit in the other modes.

The delay is just okay. I'm an analog delay fanatic, and this is just one of my least favorite analog delays. Who wants their sound to get so much quieter when you turn up your repeats? And the time range is too small.

This shines as more of a performance synth than a generative or sequencer/apr synth, IMO. The keyboard feels great to play. The knobs are fantastic. The layout is clean and creative. Leads and bass lines are a breeze. I'd describe it as 3D punch.

Oh and the price is awesome!!
