Apple released QuickTime 2.0 for System Software 7 in June 1994—the only version never released for free. It added support for music tracks, which contained the equivalent of [[MIDI]] data and which could drive a sound-synthesis engine built into QuickTime itself (using a limited set of instrument sounds licensed from [[Roland Corporation|Roland]]), or any external MIDI-compatible hardware, thereby producing sounds using only small amounts of movie data.

Following [[Bruce Leak]]'s departure to [[MSN TV|Web TV]], the leadership of the QuickTime team was taken over by Peter Hoddie.

QuickTime 2.0 for Windows appeared in November 1994 under the leadership of [[Paul Charlton (technologist)|Paul Charlton]]. As part of the development effort for cross-platform QuickTime, Charlton (as architect and technical lead), along with ace individual contributor Michael Kellner and a small highly effective team including Keith Gurganus, ported a subset of the Macintosh Toolbox to Intel and other platforms (notably, MIPS and SGI Unix variants) as the enabling infrastructure for the QuickTime Media Layer (QTML) which was first demonstrated at the Apple Worldwide Developers Conference ([[WWDC]]) in May 1996. The QTML later became the foundation for the Carbon API which allowed legacy Macintosh applications to run on the Darwin kernel in Mac OS X.{{citation needed|date=October 2013}}

The next versions, 2.1 and 2.5, reverted to the previous model of giving QuickTime away for free. They improved the music support and added [[sprite (computer science)|sprite]] tracks which allowed the creation of complex animations with the addition of little more than the static sprite images to the size of the movie. QuickTime 2.5 also fully integrated [[QuickTime VR]] 2.0.1 into QuickTime as a QuickTime extension. On January 16, 1997, Apple released the QuickTime MPEG Extension (PPC only) as an add-on to QuickTime 2.5, which added software MPEG-1 playback capabilities to QuickTime.
