This is another "noisebox" synth, similar in attitude to the previous SG-APCX (in that it is designed to be used as a sound effect generator more than a standard synth), but based on a completely different method of sound generation.
This synth is based around two sound generators- one that uses a math formula capable of chaotic behavior, and another which is an oscillator-synched noise source. The combination of these two sources produces a wide range of strange sounds, from clicks & beeps to grinding mechanical mayhem. Another interesting feature present in both versions is the "data corruption" effect, which adds another level of chaos to the mix. This is something like a software circuit bend which taps the audio stream at several points along its path, randomly mangles the signals in various ways (which are affected by various combinations of control signals from the synth's modulators) & mixes the mess back into the output.
