BIAS MINI AMP doesn't come with a separate ASIO driver, meaning that it's not possible to recognize BIAS MINI guitar amp as an audio interface/device in your DAW for recording.
Please always feed the signal physically from the XLR-Out on MINI Amp to input of your audio interface to get it work. You can also track it directly with a dynamic/condenser/ribbon microphone.
Also, we suggest you to employ BIAS Amp2 Desktop Standalone version with the MINI Amp via USB to avoid any MIDI signal interferences from your DAW (Digital Audio Workstation).
