Barry Leitch is a Scottish video game musician. He has composed music for numerous video game companies including Ocean Software and Atari Games. Barry has also composed music for a wide variety of video game consoles. His first composition was I.C.U.P.S. for the C64 and it was written when he was only 15 years old.
For Weird Dreams, Barry used AdLib Visual Composer.
Barry used a sound engine written by Richard Hutchison.
Barry used Fasttracker II.
Barry composed the songs on MODTracker for the Commodore Amiga. Then, he would rewrite the music in MS-DOS using a driver created by an unknown programmer named "Mule the Top Lad".
Barry used MEdit. The program was coded by Leslie Long and was meant to resemble OctaMED, the tracker that Ocean Software used for their Commodore Amiga music. MEdit was also used for MS-DOS games as well.
During the development of Top Gear, Barry was given instrument samples from Kemco, which were probably Korg M1 instrument samples. According to composer Hiroyuki Masuno, samples were given to Kemco by Sony, the creators of the sound chip of the SNES (SPC700).
All of these games have been verified to have been composed by Barry via his website: http://barryleitch.com
