Pre Loved Roland U110 Rack Mounted Sound Module with Cards

The Roland U-110 is a rack-mounted PCM sound module released in 1988. It’s an early example of a ROMpler, meaning it plays back pre-recorded samples rather than generating sounds from synthesis.

The soundcards included are:

• SN-U110-07 (Electric Guitar)
• SN-U110-08 (Synthesizer)
• SN-U110-09 (Guitar and Keyboards)
• SN-U110-12 (Sax and Trombone)

Overview

• 1U rackmount sound module (no keyboard)

• Controlled via MIDI

• One of Roland’s first fully sample-based modules

• Designed for studio and live use

Sound engine

• Uses PCM (sample playback) synthesis

• Around 2MB of internal sample data with roughly 99 waveforms

• Focused on:

  • Acoustic instruments (pianos, strings, brass)

  • Basic band and orchestral sounds

Polyphony and multitimbrality

• 31-note polyphony

• Up to 6-part multitimbral operation

This allows multiple sounds (like bass, strings, and drums) to play simultaneously via MIDI.

Expansion capability

• 4 front-panel slots for expansion cards

• Compatible with SN-U110 PCM cards

• Expansion libraries include:

  • Orchestral sounds

  • Guitars

  • Synth textures

  • Drums and effects

Effects and editing

• Very limited editing options:

  • Basic envelope controls (attack and release)

Built-in effects:

• Chorus

• Tremolo / auto-pan

No filters or deep sound design features.

Connectivity

• MIDI In, Out, and Thru

• Stereo outputs

• Up to 6 individual outputs for separate mixing

This made it useful for multi-track studio setups.

Interface and build

• Standard 1U rack unit

• Small LCD display (2-line)

• Simple button-based navigation

• Front-panel headphone jack

Sound character

• Aimed at realistic instrument sounds (for its time)

• Clean but somewhat thin by modern standards

• Classic late-80s digital tone

Strengths

• Early and influential sample-based module

• Expandable sound library

• Multiple outputs for flexible routing

• Reliable MIDI performance

Typical use cases

• MIDI sequencing setups

• Late-80s and early-90s studio rigs

• Layering basic instrument sounds

Summary

The Roland U-110 is a simple, historically important rack module that helped popularize sample-based sound generation. Today, it’s mainly valued for its vintage digital character and straightforward functionality in retro setups.
