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.
