https://diode.zone/videos/watch/de0e38aa-72a5-4017-a0c1-79771f8fa64f Ringer is a Kosmo format DIY synth module built around the AD633 chip. If you need to you can press it into service as a 2-channel mixer or a voltage controlled amplifier, but what it really is useful for is something like ring modulation — combining two simple waveforms to make a much more complex sound.
