I just got Bias FX and am using it inside FL Studio. However, when I use it there is a terrible buzzing sound that dominates whatever I'm playing. It sounds like something is maxing out, but I don't see any indication of that in the FL mixer. I'm getting my guitar signal into the computer using a DigiDesign MBox 2.

Here's a recording. I would really appreciate any ideas to fix this.

I ran into the same problem. There are troubleshooting options in the channel settings windows in FL Studio. The only way I was able to get the correct tone (the same that I get in Reaper with Bias) is to select the "Use Fixed Sized Buffers" option in the processing tab.


This could be a hardware driver problem. Do you have up to date drivers from your hardware. Also look at updating your video drivers as they can sometimes have an effect on your sound (as strange as that sounds).


The problem seems to be the frequency you are working at. Try switching to 192kHz instead of 44.1kHz or maybe the other way around.


VST wrapper settings > Processing > (Activate this)Use fixed-size buffers > Process maximum size buffers

You can find the VST wrapper settings in Mixer > BIAS FX 2 > There is a settings button top left on the window.


Have you tried a different Preset and see how that works or ALL presets creates a BUZZ. That could give you a clue.


most likely a buffer size problem, if not, try using 64 bit and aswell 32 bit versions of your Bias FX
