MIDI Retrofit Kit for:

Yamaha CS-80


PLEASE NOTE: Fitting a retrofit kit is a skilled job which should be undertaken only by a competent synth service engineer or fitted by us at our premises in South West London.

Note also that retrofit kits are always built to order after your payment has been processed. It then takes us up to 10 working days to build and test the kit before we can despatch it.

MIDI Retrofit Kit

  • retrofit kit

  • This retrofit kit for the Yamaha CS-80 adds the following MIDI control:

    For incoming MIDI:
    Any MIDI channel can be selected
    Notes (MIDI note numbers 36 - 96) - transpose possible
    Program change (numbers 1 - 14 top row and 17 to 30 bottom row)
    Pitchbend - (bends up and down a fifth)
    Mod Wheel (switch to enable)
    Filter cutoff frequency (of low pass filter)

    By default:
    pitchbend is controlled by pitchbend messages
    mod wheel is controlled by Mod Wheel (CC#1) and also by Aftertouch messages
    filter cutoff is controlled by CC#16
    resonance is controlled by CC#17
    Volume is controlled by MIDI volume (CC#7)
    Sustain is controlled by Sustain (CC#64)
    Portamento is controlled by Portamento (CC#65)

    however, any controller or aftertouch or velocity can be mapped to control other things so for example velocity could be mapped to control volume.

    This kit is to receive MIDI only, no MIDI can be sent from this keyboard.

    MIDI In, & Thru sockets
    Push button (for programming the MIDI setup)
    Setups are stored in non-volatile memory (Eeprom)

    The kit comprises the following items:
    Circuit board - fits in the base of the CS-80
    Small pack - contains DIN sockets and mounting hardware
    Large pack - contains cable assemblies
    User instructions - How to change from default settings and general instructions
    Fitting instructions - step by step fitting guide plus diagrams of where to connect what

    All kits are fully checked and tested before despatch

    Note: Our retrofit kits are not intended for installation by the end user. They should always be fitted by an experienced synth engineer, particularly this model as it is hardest of all our kits to fit.
