Fruity SoundFont Player is no longer for sale, only legacy purchases are still supported. Use DirectWave as alternative.
The Fruity SoundFont Player is currently only available in 32 Bit format. Unfortunately it can't be bridged to work in FL Studio 64 Bit.
SoundFont Player does not load in FL Studio 64bit, and gives the error message:
Your options are as follows:
So what's the problem with 64 Bit? We no longer have access to the source code and so can't compile a 64 Bit version. We may be able to develop a custom wrapper in future but for now attempts to do that have failed and further research is low on the priority list.
For your information: The following features & plugins rely on 3rd party code that is not available in 64 Bit at this time - Buzz Adapter, Edison 'Clean Audio' function*, FL Slayer, Fruity Soundfont Player*, Synthmaker/Flowstone*, Wasp/Wasp XT.
