>8FL (pronounced either "eight-eff-ell" or "eighth floor") is a livecoding musical instrument for the Renoise music tracker digital audio workstation. It works by opening up a Fennel REPL into a running Renoise application and providing a library of music-focused sequence operations that can control and populate the active song. It is intended for live performances but can be used for algorithmic composition in the studio as well.
