D-110 - Multi Timbral Sound Module © 1988 Roland.
The Roland D-110 was a rackmount multitimbral sound module based on Roland’s Linear Arithmetic (LA) synthesis technology. Developed by Roland Corporation, it was the rack version of the D-10 synthesizer, offering the same sound engine in a compact 1U format designed for studio and MIDI rack setups. The D-110 featured 32-voice polyphony, 8-part multitimbrality, built-in digital effects such as reverb and chorus, and a wide range of preset tones combining sampled attacks with synthesized waveforms. It became a widely used studio module during the late 1980s and early 1990s, particularly in MIDI sequencing environments.
The D-110 is essentially the rack-mounted counterpart of the Roland D-10, sharing the same LA synthesis engine and sound architecture.
Its compact 1U rack design made it extremely popular in professional MIDI studios where rack space was at a premium.
Like other LA synthesis instruments, it combined short PCM samples for attacks with synthesized waveforms for sustain, creating the distinctive Roland “late-80s digital” sound.
The module was often used in multitimbral MIDI setups, allowing composers to drive multiple parts from a single device in sequencing environments.
It was widely adopted in pop, film scoring, and television production during the transition from analog to fully digital studio workflows.
The D-110 supported the same preset compatibility as the D-10, allowing sounds to be shared between keyboard and rack formats.
It included onboard digital effects, reducing the need for external processors in small studio setups.
Alongside the D-50 and D-20 family, the D-110 helped solidify Roland’s dominance in LA synthesis during the late 1980s.
