Moog E346A Song Producer Midi Sync Interface

The Moog E346A Song Producer is an uncommon MIDI and sync interface designed in the mid-1980s for the Commodore 64. It served as a control hub for MIDI instruments and pre-MIDI drum machines. It allowed musicians to sync multiple devices using its MIDI and trigger outputs, making it an useful tool in the early days of digital music production. Though not widely adopted, it remains a unique example of Moog’s venture into MIDI technology.

The Song Producer connected via the Commodore 64’s expansion port and featured one MIDI input, one MIDI thru, four MIDI outputs, and eight drum trigger outputs. It also included clock sync, two footswitch inputs, and software for sequencing and MIDI processing. The interface enabled patching and synchronization between analog and digital gear, offering an early glimpse into computer-assisted music production.
