The Roland U-110 is a synth module (sample playback or "Rompler" type) produced by Roland Corporation in 1988.
Roland's answer to the E-mu Proteus, the predecessor of the more successful U-220 module and U-20 keyboard and the ancestor of the prototype T-110, the U-110 was Roland's first dedicated sample playback synth. It used ROM to store sounds rather than loading them from disks into RAM, hence it was not a true sampler as it could not sample sounds.
The U-110 contained a base 2MB of sounds stored in ROM. It could be expanded with up to 4 Roland SN-U110 sound library cards, unlike the more popular Roland U-220 that could only accommodate two. It had six individual outputs.
|Polyphony||31 Voices (Certain sounds, such as V-MIX and Dual/Detune sounds, reduce this to 15)|
|Sound Generator||DC-PCM Sound Generator|
|Base Sample ROM||2MB Consisting of 99 Sounds (mainly pop/rock no synth sounds (except synth bass))|
|Patch Storage||64 Internal memory locations|
|Expansion||2MB of extra sounds can be added by using up to 4 Roland SN-U110 PCM Cards|
|Outputs||1 Stereo mix output and 6 individual outputs (different output modes are available) also a headphone socket is attached to the mix output|
|Multimbral||Yes. 6 Parts splitting the polyphony with each part i.e. no dynamic voice allocation|
|MIDI Implementation||Good. All parameters are configurable using Sysex and Sysex dumps are easy to carry out. Midi IN/OUT/THRU available on the device.|
|Effects||Basic Digital Chorus and Tremolo|
|Display||16x2 LC Display|
|Control||6 Front panel buttons and a volume dial for the mix/headphone output.|
|Demo Songs||There are 4 on-board factory demo songs which demonstrate the sound capabilities of this unit quite well.|
Tests carried out; 1. S-RAM Check,
2. LCD Check (display switches on all pixels),
3. KEY/LED Check (pressing down a key will blank out that keys name on the display and if there is an LED in the key that will light up as well if working),
4. Battery check,
5. MIDI Check (using a midi cable connect midi in to midi out on back of unit. Midi message light will flash and a graphical representation of data flow will appear on the display),
6. Wave ROM check,
7.ROM card check,
8. DAC Offset Adjust,
9. DAC MSB CHECK,
10. Sound Check (By pressing <- and -> you can cycle though the modules voices. if working a tone should be heard from headphones or other connected output device (mix output) also pressing [dec] or [inc/enter] checks the effects),
11. Output check (this checks the individual voice outputs use <- or -> to change the currently selected output and check to see if a test tone is emitted from that output).
