The Roland U-110 is a synth module (sample playback or "Rompler" type) produced by Roland Corporation in 1988.
Roland U-110 Wikipedia
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.
Tests carried out:
- S-RAM Check,
- LCD Check (display switches on all pixels),
- 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),
- Battery check,
- 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),
- Wave ROM check,
- ROM card check,
- DAC Offset Adjust,
- DAC MSB CHECK,
- 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),
- 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).
