The Roland DDR-30 measures 3.5"x 19"x 12" (H x W x D) and it's two units tall. The module sports a large VFD display window. All patch data is shown here from selected voice to parameter information. Below the window are a series of buttons for Edit write, Set write, Bank select, and then eight drum set buttons. Next to these are rocker switches for Instrument Select (up and down) and Patch Select. To the right of these are six edit buttons, arranged in two rows, including: Forward; Back; Voice; Gate; Pitch; and EQ. Next to these are four more to control Pad sensitivity, Cartridge operations, Copy button and MIDI settings. Next to these we have a large Alpha Dial to modify voice parameters. Finally we have a memory cartridge slot, a MIDI message light, and a Power button. |

The Roland DDR-30 "Alpha Drum" is a digital PCM drum module built by Roland, in early 1985.[1] It was introduced during 1985 Summer NAMM industry trade show in New Orleans.[2]
The Roland DDR-30 Digital Drum module is designed to pair with PD-10 and PD-20 pads to form the Alpha Drum System, or via MIDI controller (e.g. Roland Pad 8).[3] The DDR-30 and Alpha Drums was the first-generation of Roland electronic drum sets.[4]
The Roland DDR-30 measures 3.5"x 19"x 12" (H x W x D) and it's two units tall. The module sports a large VFD display window. All patch data is shown here from selected voice to parameter information. Below the window are a series of buttons for Edit write, Set write, Bank select, and then eight drum set buttons. Next to these are rocker switches for Instrument Select (up and down) and Patch Select. To the right of these are six edit buttons, arranged in two rows, including: Forward; Back; Voice; Gate; Pitch; and EQ. Next to these are four more to control Pad sensitivity, Cartridge operations, Copy button and MIDI settings. Next to these we have a large Alpha Dial to modify voice parameters. Finally we have a memory cartridge slot, a MIDI message light, and a Power button.
