Yamaha E-75 Son Of GX modification
Got this organ with guts from the infamous GX-1 and the CS80.
After the modification we got full access to the 2 polysynths (7 voices 2 OSC and LP+HP filter each) and the monophonic bass synth.
3 times 16 controls in total:
4 Filter controls (Low pass filter frequency, Low resonance, High pass filter frequency, High pass resonance)
5 stage Filter Envelope Generator (Initial Level, Attack level, Attack, Decay, Release)
4 stage Voltage Controlled Amplifier Envelope Generator (Attack, Decay, Release, Sustain)
3 waveforms possible for use in parallel (saw, square, narrow pulse)
CV-control for LPF and VCA for each manual. LFO and sequencer control possible:)
Speed control for the triple chorus + Input and different outputs.
Curetronic shape LFO now included
