High Quality Content by WIKIPEDIA articles! The AIR Users Blog is a Blog which is the focal point of a community of around 50,000 users a month. All of them are joined by their interest and use of AIR (Advanced Instrument Research) software plug-ins, part of Digidesign Pro Tools. It was started in October 2008 by Russ Hughes, a musician based in London, UK. It is independent and has no official links with AVID, the owners of the software.
