Sibelius

Sibelius Software Ltd. is a software business and a part of Avid Technology that develops and sells music notation software.

The company was named after the Finnish composer Jean Sibelius, and was founded in April 1993 by twins Ben and Jonathan Finn to sell the Sibelius notation program. It went on to develop and distribute various other music software products, particularly for education. In addition to its head office in Cambridge and subsequently London, Sibelius Software opened offices in the US, Australia and Japan, with distributors and dealers in many other countries worldwide.

In August 2006 the company was acquired by Avid, to become part of its Digidesign division, which also manufactures the leading digital audio workstation Pro Tools.

In July 2012, Avid announced plans to divest its consumer businesses, closed the Sibelius London office, and laid off the original development team,[1][2][3] despite extensive protests on Facebook and elsewhere.[4][5] Avid subsequently recruited some new programmers to continue development of Sibelius.

The company has won numerous awards, including the Queen's Award for Innovation in 2005.
