Some of the most successful music producers started by mixing music in their bedrooms.
Mark Vidler, of Go Home Productions, does just that using well established software such as Acid Pro.
He has worked with David Bowie, The Doors and Blondie.
He explains how he remixed the BBC News theme for a BBC News website feature.
