A simple little tool for replacing fmod event GUIDs of a *.bank file. Only works for event GUIDs, not effects or buses etc. Modifies the file in place, so make a backup of the old one. Only tested with bank files generated by FMOD Studio 2.01.05
List all event GUIDs:
guid_replacer.exe your_audio.bank
Replace GUIDs:
guid_replacer.exe your_audio.bank [GUID to replace] [what to replace it with]
guid_replacer.exe your_audio.bank {bc5e80f9-a380-47c9-8799-3e02eea94feb} {aabbccdd-eeff-00ff-aabb-feffefbbaacc}
Multiple replacements can be chained like this:
guid_replacer.exe your_audio.bank {GUID_A1} {GUID_A2} {GUID_B1} {GUID_B2}
