Soldered together the rat king modular tones 3340 oscillator today (actually it's the second I've built), and just ran it through the QPAS for fun (Sawtooth input, !! inputs modulated by the square and triangle waves). The module nearest the camera if you're that bothered.
Really fun and easy little build, highly recommended for someone looking to build their first oscillator. Attenuators on the PWM and FM inputs would have been nice, but would have made it a little cramped to solder. The FM input doesn't goes as wild as I'd have liked, but it's more or less set for musical tremolo effects. A trade off I guess for a super simple DIY oscillator. By far the simplest oscillator I've built to date, but its pretty much fool-proof (single board, easy calibration, sounds great). Highly recommended if you're just getting started in eurorack DIY.
The Rat King was sequenced by the mother 32, which also provided the envelope for the QPAS. Subharmonicon added some backing, with the hexinverter BD9 for a kick. Some noise into blades for fun. Bucket tonnes of delay and reverb (strymon).
