We switched from FSB4 to FSB5 in version 4.39 of FMOD Ex/Designer.

Why do you want to make a bank in FSB4 format? Are you porting an existing game made with FMOD Designer to a new platform?

Hello. If I am making a mod for Deus Ex: Human Revolution that requires fsb version 4, can I contact you to get the FMOD Ex API? The game is old and used fsb v4. The current FMOD generates fsb v5, which is not compatible with the game engine. Can you help me with this?

It appears you’re already getting help with this in [another thread](https://qa.fmod.com/t/fmod-designer-fsbankex-has-been-made-public-fmod-ex-api-access-requests-here-only/23724/41), so I’ll close this one.
