Product Information

Our featured product, the MIDI Module 3000 (MM3k), is a MIDI switcher solution for the vintage Korg SDD-3000 (SDD3k) rack delay. Historically, the SDD3k's programs have only been accessible via footswitch operation, or by the pressing of the front panel tactile buttons. With the use of the Midi Module 3000 (SDD Series), a vintage Korg SDD-3000 is now capable of interfacing with a MIDI footswitch controller.
