Audio Units (AU) is a system-level plug-in architecture provided by Core Audio in Apple's macOS and iOS operating systems.


If you're going to use BIAS FX 2 in DAWS on Mac, for example, GarageBand and Logic Pro X will support AU.


VST (Virtual Studio Technology) is a plug-in effects processing engine for DAW software that was created by Steinberg.


If you'd like to use BIAS FX 2 in DAWS on Windows or Mac, most of the DAWs support VST files, for example, Ableton Live, Cubase, etc...

You will need an AAX format plugin while you're using AVID Pro Tools.





After downloading, launch the installer and simply follow the instructions to complete the installation.




Launch Finder -> Applications, then launch BIAS FX 2 or go to Launchpad and choose BIAS FX 2.



Click on the Start menu and launch BIAS FX 2 Application.

Important Notes:

  • If you see the 'Login Failed' error message, please refer to this link: Login Failed: 0, 7, -201

  • Please make sure you are using the same account you used for the purchase. Logging in with another (incorrect) account will change the license tier and possibly revert the program back to Demo Mode.

  • Our desktop products are available for activation on 5 computers max (doesn't matter if it's PC or Mac). More activations will result in Demo Mode.

  • To deactivate a previous activation, go to our user center and find the 'Manage License' option on the 'License & Download' page.

  • If the license keeps showing 'Demo' and is unable to activate to a full license, please temporarily disable your anti-virus software/firewall and try again. 

  • For further assistance, please contact support here.


Audio Setting

* Before configuring the software setting, please make sure you switch OFF 'Direct Monitor', or turn the MIX knob all the way to 'DAW'. Otherwise, you'll only be hearing the "dry guitar signal" no matter what.

To get a sound out of BIAS FX2, you need to go to the 'Audio Setting' page to set up your input/output device, sample rate, buffer size, and MIDI input device.

*Plugin version doesn't have the Audio Setting tab, as it follows the setting of the DAW. Please find the setting/preference tab for your DAW for further configuration. 


  • Output Section

- Audio Device Type (Windows only)

Select ASIO. (please do NOT use Windows Audio to avoid audio latency).


*If ASIO is not an option, please download and install the latest ASIO4ALL driver at

Please also make sure to download and install the latest driver for your audio interface from the manufacturer's website.


- Output Device

Select your audio interface as your Output Device

- Output

We recommend you set it to 'Stereo' unless your setup does not allow stereo playback.

- Output Channel

Choose the corresponding outputs (on your audio interface) and make sure they're connected to your studio monitors/speakers or headphones.

Make sure you can hear a test tone when you click on 'Output Check', otherwise, the hardware configuration is probably wrong. 



  • Input Section

- Input Device

Select your audio interface as your Input Device 

- Input

If you're using only one input for your guitar, please choose 'Mono'

- Input Channel

Choose the corresponding input(s) (on your audio interface) connected to your guitar/instrument.

Make sure you can see the green input signal in the 'Input Check' bar when you play guitar, otherwise the configuration is probably wrong.




  • Sample Rate & Audio Buffer Size

- Sample Rate

Please choose the desired sample rate (supported by your audio interface).

We recommend you stick with 44100 or 48000 Hz to avoid CPU overload, which will in turn cause crackling/popping noise (a higher sample rate requires more CPU usage).

- Audio Buffer 

Please choose the desired buffer size.

We recommend you stay within 256 ~ 512 samples to achieve the optimal performance without overloading the CPU, which will in turn cause crackling/popping noise (lower buffer size requires more CPU usage).




  • Active MIDI Inputs (Optional)

Please select the MIDI inputs that you want to use. For further information on how to set up your MIDI device, please refer to 'How to Use MIDI Control in BIAS FX 2 Standalone Version?'.





Additional Setting


The level of the input signal can affect the overall gain and saturation of your tones, and the level of the output signal can affect your overall recording level.  

Here are several tips to help you optimize your input signal : 

  • For optimal performance with an electric guitar (or bass), we suggest that you use an audio interface with a “Hi-Z” or “Instrument” input.
  • If your audio interface offers input knob(s), it is best to adjust it for keeping the input level (going into the plug-in) in an optimal range. Try to avoid clipping in the input stage of your audio interface.

  • Guitars with active pickups may have a hotter output than passive pickups. If your guitar utilizes active or particularly high output pickups, we recommend that you set your audio interface or preamp's input PAD to ON, if available.

  • To use the auto input level detection, please hit the 'AUTO' button next to the Input Volume bar and strike the strings with your utmost power. The program will detect your playing and help set it to an optimal level. After that, you may click the 'LOCK' button to ensure that you're always using the optimized input level.

  • The input and output meter also provide guidance which indicates that the signal is too high and might be clipped.
