This is a panel for the Korg DW-8000. It should also work with the rack version EX-8000 but I couldn’t test it.
If the synth’s midi output is connected to the panel’s input, the panel can receive sysex program dump data, and update its values according to the synth’s current program. There is two ways this can happen:
– if the “Load” button is clicked, the panel sends a dump request
– if the panel receives a midi program change message on the midi channel used to communicate with the synth, it will send a dump request. The synth always sends a midi program change message when a new program is selected.
The format is “compressed binary + ressources”.
