Hello: Fxb is not a sound format. It is a vst format for saving banks of patches for any given vst plug-in. Your fxb files are proprietory for whatever plug-in they were created on.

I have some sounds in fxb format. I am able to see the fxb files in SFZ but when I attempt to lode them I hear nothing. Unlike that, WAV files are no problem to open and lode them in to sonar and play on my keyboard. Thanks Caglar
