Roland
The Roland D-110 is a 1988 rackmount sound module — the upgraded rack version of the D-10 and rack counterpart to the D-20. It delivers Linear Arithmetic synthesis, second-generation D-50 style, using tones, partials, and timbres. It has 32-voice polyphony, on-board drum sounds, reverb, internal/external memory, and six individual outputs. It requires external MIDI control. Programming is tricky but yields characteristic LA textures. Its filter resonates but does not self-oscillate. It is a cheaper alternative to the D-50, offering decent acoustic and synthetic sounds — but no keyboard, no sequencer, and no intuitive interface.
