BIAS FX
BIAS FX is a virtual guitar amplifier and effects processor VST plugin developed by Positive Grid. It models a wide range of classic and modern guitar amps, cabinets, and effect pedals, allowing musicians to shape guitar and bass tones with studio-quality precision. The plugin runs inside compatible digital audio workstations (DAWs) such as Reaper, Pro Tools, Logic Pro and others, and is popular among guitarists, bassists and producers who want amp and effect modeling without physical hardware.
AI Recommendation
1 suggestionBIAS FX is a VST plugin that runs inside your host DAW, not a standalone application, so it updates through Positive Grid's own installer, not through your DAW or the Mac App Store. The good news is that Positive Grid added native Apple Silicon support to BIAS FX 2 in version 2.7.0, released in November 2023, so if you are still running an older Intel-only build under Rosetta, you can upgrade to the native version. Download the current version from Positive Grid's website or use their desktop application manager (Positive Grid Desktop / BIAS FX standalone app) to pull the latest plugin build. After updating, your VST will run natively on your M-series Mac with better performance and lower CPU overhead. If you use Pro Tools specifically, make sure your Pro Tools installation is on version 2023.6 or later — earlier versions do not properly support native AAX plugins on Apple Silicon.
