Which software is known for notational capabilities and includes features like varied input/output?

Sibelius is recognized for its robust notational capabilities, making it a leading choice for composers, arrangers, and educators seeking to create traditional sheet music. The software provides features that support varied input methods, such as MIDI keyboards or mouse input, allowing users to enter notes in a way that best suits their workflow. Its output features also allow for high-quality printing and PDF creation, accommodating different formats and layouts according to the needs of musicians and ensembles.

In contrast, while Apple Logic Pro, FL Studio, and Avid Pro Tools are excellent digital audio workstations (DAWs) with a focus on audio production, mixing, and editing, they do not prioritize music notation in the same way. Their strengths lie in sound manipulation, recording, and production, rather than in professional-quality score writing and the intricate handling of musical notation that Sibelius excels in.
