OB-6 Low Frequency Expander 

Just received the Low Frequency Expander for the OB-6 (and Prophet 6) and doing some experimentation. Here, LFO 1 controls filter frequency, LFO 2 controls resonance and LFO 3 controls distortion amount. The envelope adds a subtle scoop in pitch to Osc 2. This module adds an incredible amount of flexibility to the OB-6. Thanks, Steve Hunt!
