KEDEM4
Four switches. Same screen.
The same display, the same AirMIDI, the same editor as the Kedem 6. Four switches across 140 mm, for the board that has run out of room.
Discontinued
The first generation is out of production. Every unit we built has an owner.
We still support them: manuals, firmware, and repair.
