The U-110 is an early ROMpler in the same family as the U-20 and U-220 and it completed Roland's transition from synthesized instrument sounds (or "sample and synthesis") to sampled instrument sounds. It can be expanded with the SN-U110 series of expansion cards. It should not be confused with the D-110, which is an LA (linear arithmetic) synthesizer from the same era. Both were commonly found together in studios.
The sounds of the U-110 are focused mainly on sampled representations of acoustic instruments, which had previously been lacking in the world of analog and FM synthesizers. While it was fairly groundbreaking and sold well, used units sell very inexpensively. The U-110 was surpassed by modules with larger sample ROMs over the next few years and doesn't have much of that "collectible charm", being a simple black box.
The MIDI implementation is thorough and the unit can be configured via Sysex commands. It has IN, OUT, and THRU connections. It also has four built-in factory demo songs.
It uses a standard CR2032 lithium battery for its patch memories.
