MIDI Retrofit Kit for:

Yamaha CS-70M


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.

    Sustain is controlled by Sustain (CC#64)
