Laborejo (Esperanto: Workshop) is a MIDI sequencer based on classical music notation. Its main purpose is to compose and produce "traditional" music, such as instrumental pieces, soundtracks and other music normally played back by samplers.

Unlike other notation editors Laborejo is not meant primarily to print out sheets of notation but to create music for your computer: You get all the tools you know from other midi sequencers for maximum fine control to get exactly the music you want!

Working in Laborejo is very fast and efficient by using a combination of midi input and typing.
