"Multitrack recording of the Yamaha CS-80. All sounds are made with the CS-80, except drums.
Very special thanks to Jair for lending me his CS-80 and Cox Electronics CS-80 programmer. Check out the Cox Electronics upgrade: https://cox-electronics.com"

Pic of the programmer and details on the upgrade via https://cox-electronics.com:
"Here is a summary of features provided by the upgrade:
- 3 banks of 128 free programmable performances
- 6 banks of 128 free programmable presets
- possibility of dumping performances and presets by SysEx
- MIDI sending and receiving of almost every parameter (more then 100 CC messages)
- full MIDI support of the CS-80 keyboard's polyphonic aftertouch
- special keyboard settings like octave transpose, velocity and aftertouch response
- automatic keyboard double trigger remove setting
- programmable chord memory
- foot pedal can be programmed sending CC messages (3 simultaniously)
- possibility of manually disabling a defective voice
- autotuning possibility of all 16 oscillators
- 3 extra separate global LFOs for VCO, VCF and VCA (with MIDI clock sync)
- special playmodes providing various algorithms like voice stealing, monophonic and polyphonic in unison with detune setting
- VCF and VCA envelope time can seperately be switched to 5 times the length
- very much care has been taken so the "analog feel" of the CS-80 stays authentic to original
Also extensive service needs to be performed and lots of modifications like:
- all electrolytic capacitors will be replaced since the old ones are bad (around 450)
- all sliders and switches will be professionally cleaned (around 80)
- cleaning and readjustment of the keyboard contacts
- cleaning of the polyphonic aftertouch parts
- removal of 5 old boards, to be replaced by 7 new boards. Now the very rare YM26600 and YM26700 chips are replaced by modern electronics
- around 250 additional wires, several modifications to the boards and around 70 extra capacitors are needed to make everything possible
- complete calibration of all circuit boards
- a nice programmer is included and only one connector will be mounted on the back of the CS-80
Almost every parameter of the synthesizer can be stored in memory and can receive and send MIDI data. For only a few knobs and sliders this is not possible:
- detune CHII slider
- the four touch response sliders
- the master volume knob (exp can be controlled by footcontroller and MIDI)
- foot pedal exp/expwah switches
- sustain slider (although it can be controlled on/off by footswitch and MIDI)
- the switches and knobs of the tremolo and chorus section"
