SYM7 Release History

Build 7.4.9577.11476 posted 22 March 2026

• Fixed issue that caused the SYM7 to fail when running under Win11 24H2 or later with a recent Windows update.

  The update replaced the MIDI 1.0 stack with MIDI2.0 and this broke the app's MIDI implementation.

  The app now detects the presence of MIDI2.0 and uses an alternative MIDI implementation that is compatible with MIDI2.0.

  As this is a breaking change it may be necessary to remove your existing version of SYM7

  (Settings>Apps>SYM7>Remove) and reinstall SYM7 from https://www.fm-alive.com
