• Added Sound Designer and direct QuickTime output formats,
• Added support for MACE-3 and MACE-6 compression in SoundEdit files,
• Added support for AIFF and 'snd ' files explicitly encoded with the 'twos' and 'raw ' codecs,
• Re-wrote the MIDI code from scratch and added OMS support and a new MIDI Preferences pane,
• Included new ZSS drivers with MTM support,
• Added Script menu which lists the scripts in a “Script Menu Items” folder,
• The volume preference is now relative to the system volume, thus will have no effect on other applications’ volume, and can now go from 10% to 150%,
• Fixed sample rate specification with AIFF files due to an incompatibility with CodeWarrior and extended floating point numbers,
• Fixed a bug which could cause a hang while playing MED/OctaMED files with the ZSS driver set as preferred,
• Fixed a problem which caused some files to be left open when dragged to the Play List,
• Now properly calculates the length of MPEG Layer I files,
• Removed two-byte click at the beginning of converted System 7 sound files,
• Added Info window to provide more information on a sound file,
• Added extensive AppleScript support,
• Added a “SoundApp Home Page” to the Help menu if Internet Config is installed,

2.2.1, December 5, 1996.
• Corrected a problem upgrading the preferences file from 2.1.1 to 2.2, which would result in a corrupted file. If you used version 2.2, you’ll need to reset your preferences.

• Work around a bug in QuickTime 2.1 which prevented many MIDI files from playing,
• Fixed a bug which prevented MOD conversion on 680x0 Macs,
• Fixed a bug which caused random shuffling of Play Lists to not be very random.
2.2.3, February 26, 1997.
• SoundApp no longer gets confused if the Controls Palette is closed while playing a file from a Play List,
• Made another attempt to allow SoundApp to work without a PowerPC-native AppleScript,
• Corrected two AppleScript dictionary problems (one which prevented conversion to a specific format type and another which prevented saving a Play List to a specified file),
