Convert ROL files online for free
The converter easily converts your ROL file to various formats - free and online. No Media Player or extra software needed.
The converter also works in reverse, so you can convert other Audio formats to ROL with high quality output.
The .ROL extension primarily refers to the AdLib Visual Composer music format, a relic from the golden age of DOS gaming and FM synthesis. Unlike modern audio files like MP3, a .ROL file does not contain recorded sound; instead, it holds "piano roll" sequencing data - instructions that tell the legendary OPL2 synthesizer chip which notes to play.
Because these files are essentially digital sheet music for obsolete hardware, you cannot open them in standard media players like Windows Media Player or iTunes. Furthermore, AdLib .ROL files often require a companion BNK (Bank) file to define the instrument sounds; without it, the music may not play or will sound incorrect. A secondary, less common use of the extension is for PianoDisc systems, which use proprietary data to control solenoid-based player pianos.
To make these files usable today, the best approach is conversion. For listening, convert .ROL to MP3 or WAV to capture the authentic FM sound. For editing or remixing in modern DAWs like FL Studio, convert them to MIDI. Simply drag your .ROL file to convert.guru to identify the format and transform it into something you can actually use.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ROL converter.
