Pittsburgh Modular's Chain Rector module is a quadraphonic voltage influenced chaotic waveform generator. It uses 4 LFOs with variable wave shape to produce lots of complex modulation effects in a compact module. LFO 3 is normalled to the influence of LFO 2, which is normalled to the influence of LFO 1. Without any patching you can pull three cascaded modulation sources out of the Chain Reactor with the free running LFO 4 to spare. The Chain Reactor is capable of subtle flowing modulation effects and glitchy rhythmic stutters.
