ScoreCloud is a software service concerning music notation created by DoReMIR for Mac OS X, Microsoft Windows, iPhone and iPad. It is furthermore a web application for sheet music storing and sharing. The main functionality of the software is the automatic creation of music notation directly from music performance or recordings. E.g. recorded from a performer singing, playing an instrument or for best results from a MIDI keyboard.
ScoreCloud comes in two varieties – ScoreCloud Studio and ScoreCloud Express. Studio is an application software available for Mac OS X and Microsoft Windows and contains full editing capabilities, as provided by common music notation software. Express is a mobile app available for iPhone and iPad and contains simplified editing capabilities.
Other software provides functionality to either record audio, or transcribe audio to MIDI, or import midi to transform it to sheet music, or to share sheet music online. While you can combine such software as a tool chain, ScoreCloud is the only service offering all steps at once. That might be its unique selling proposition. ScoreCloud's ability to transcribe real-time MIDI input into sheet music has been praised in the British music technology magazine Sound on Sound.
