"The Sismo Qadrox is a squarewave generator with four analog oscillators built in eight step sequencer, input to external clock, CV and sync outputs.
The audio outputs have two options, one mono by the 3/4 inch (guitar plug) and RCA stereo, split the oscillators two per each side. Front panel have nine potenciometers, is the CV sequencer (0-5 Volts) controlling the sound generator.
The potenciometer in the middle is the sequencer pitch control.The lower panel have an external clock input and the clock output, internal or external and the CV sequencer output. The one switch change completely the sound generator, increment some sweeps, noises and lfos, charge and discharge capacitors. The another switch is a sequencer reset.
Features
- Create powerful noisy rhythms and unpredictable sounds
- Portable design in wood and acrilic
- Sync by Clock, lead or follow the pitch
- CV output
- Stereo oscillators output

via the seller: "This particular model is an old Wave 2.2 with the latest Wave 2.3 software installed (V 8.3), effectively making it a fully functioning Wave 2.3 with 16 oscillators (two per voice), 12-bit resolution, dual modulation wheels, SSM 2044 VCFs and 8-part multimbrality. I'm led to believe this model was made between 1982 and 1984. I had it shipped over from Germany after a service just over two years ago, I used it for about a month and after that I stored it away as I had no time to study it properly. It is a complex synthesizer, with extremely interesting sounds and a unique character. It has a few scuffs due to its age but apart from that it is in perfect conditions..."
Update via Qwave in the comments: "The serial number is most likely not 265. All pictures and my PPG wave 2.3 with the past PPG firmware 8.3 show this number during booting. The serial number of the PPG waves is written on the back. I guess, all version 8.3 EEPROMs show this serial number."
