KORG KPR-77 Retrofit MIDI Interface (work in progress)

Published on Jul 24, 2016 Harry Axten

"This is a project I'm currently working on. It adds MIDI to the KORG KPR-77 analogue drum machine from 1983. It installs internally; requiring no case mods to fit it, as it fits in the battery compartment and re-uses the DINSYNC connector for the MIDI input.

There are still things to be done, such as redesign the printed circuit board and add the final feature set to the firmware, but I aim to have a kit for sale this year."
