Roll (ROL) is an audio format that houses musical instructions. It is similar to sheet music in that it only houses the instructions for playing music, but not the actual sound itself. ROL files must be loaded in conjunction with instrument (INS) files or with an instrument bank file (BNK) which defines the sound of the instruments that will play the ROL instructions. In particular, ROL was used by Ad Lib and their AdLib Visual Composer program.

The AdLib Visual Composer program stores the title "ROLL" in the format's metadata, implying that the name is short for "piano roll", which is fitting for what it is. Because the format has become archaic, the origins of ROL are difficult to find. Some sites have claimed that it predates Ad Lib and is an abbreviation for the company Roland, however, this seems unlikely since the format only stores OPL2 data, not MIDI or LA32 data.
