Notion allows users to perform composition using a computer keyboard/mouse, MIDI keyboard, MIDI guitar, MIDI file, MusicXML file, or handwriting recognition. The application automatically handles aspects of music notation based on the input, such as stem direction and alignment of different rhythmic values.
From version 3 onward, Notion also supports ReWire, third-party VST effects and other third-party sound libraries, including presets for products from the Vienna Symphonic Library, EastWest, Miroslav Philharmonik, and Garritan Personal Orchestra.
Playback and Performance
The playback engine provides options for real-time tempo control as it interprets score marks, such as articulations and performance techniques.
Integration with Studio One
Starting with version 3.3 in 2016, the Studio One DAW (also developed by PreSonus) is integrated with Notion (version 6 and above). This integration allows the two applications to perform real-time audio and MIDI streaming (via either ReWire or PreSonus’ own UCNETprotocol) to transfer audio, note, track, VST and score data directly between each other. This connectivity can occur either with both applications running on the same computer, or on multiple computers connected to the same network.
This integration was expanded further by Notion versions 6.4 (May 2018, following the release of the Chord track for Studio One in version 4), which allowed the transfer of chord-level information between the two applications, and 6.5 (Jan 2019), which enabled the automatic translation of drum tracks into standard percussion notation.
