Bring the power of MIDI to your Roland TR-808.

Kenton’s Roland TR-808 Retrofit Kit gives you enhanced control over your Roland TR-808 using MIDI, allowing you to control it from your DAW, sequencer or other controller.

PLEASE NOTE: Installing a retrofit kit is a skilled job which should be undertaken only by a competent synth service engineer or installed by us at our premises in Tadworth, just outside 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.
