The Roland XP-80 is a music workstation that uses digital PCM subtractive synthesis and combines an updated version of the JV-1080 synthesizer engine with the sequencer capabilities of the Roland MRC-Pro sequencer. The XP-80 was introduced in 1996 and is now discontinued.

The XP-80 has a 76-key semi-weighted keyboard. A smaller 61-key variant, the XP-60 was introduced shortly afterward. The synthesis engine is capable of 64-voice polyphony and 16-part multi-timbrality. The XP-80 includes the 128 General MIDI instrument set, as well as 384 additional preset instruments ("patches" in Roland parlance), for a total of 512 preset patches. Additional user memory is provided for making copies of up to 128 patches, allowing the user to edit patch parameters and save them in memory. There are 8 preset percussion instrument combinations (called "rhythm sets") and 2 user configurable rhythm sets. The XP-80 includes 64 preset combinations of up to 15 existing patches and 1 rhythm set. These patch and rhythm set combinations are referred to as "performances" in Roland parlance. There are an additional 32 user memory locations to store user configurable performances. There is a built-in backlit LCD display of 320 by 80 pixels.

The onboard sequencer is capable of storing up to 60,000 notes of recorded musical performance and has a clock resolution of 96 parts per quarter note. It's capable of storing up to 100 patterns and 1 song at a time in memory, but can also load and play music sequences directly from floppy disk using the built-in floppy disk drive.

The XP-80 includes 4 user accessible expansion slots (located under a removable cover on the bottom of the unit). Each slot can accommodate one SR-JV80 expansion board. A total of 21 SR-JV80 expansion boards were released by Roland. Nineteen were sold (SR-JV80-01 through SR-JV80-19), while 2 were given away as demonstration expansion boards for various promotions (SR-JV80-98 and SR-JV80-99).

A built-in 3.5" floppy disk drive provides removable data storage for up to 1.44 MB of music sequences, sequence chain-play playlists, groove quantize settings, additional patch, rhythm set, performance and system settings storage.
