The Gamma Wave Source is a really strange wavetable oscillator with effects and two entangled oscillators. The effects are really unpredictable but exciting to use and can be stepped through automatically by a built in LFO. The waves are plentiful and are tuned for easy octave and semitone switching. Both oscillators are sadly run from the same lookup wave meaning there is only one 1V/oct input and really it is just a single VCO. However, you may select the waves independently and offset tuning by semitones or octaves - sadly no detune is available.
This module is in great working condition with just some moderate rack rash.
