FAQ

Does BIAS AMP 2 work on the latest iOS?
Recent user reviews report significant technical issues on iOS 16.5.1 and 16.6, including persistent static noise and digital distortion. While the app is listed as compatible, these audio glitches currently impact usability for many users.
Can I use BIAS AMP 2 iPhone purchases on my iPad?
No. According to multiple user complaints, Positive Grid requires separate purchases for the iPhone and iPad versions of the app and its expansions. There is currently no universal purchase support for this product.
Is BIAS AMP 2 better than Cubasis 3 for guitar tones?
BIAS AMP 2 offers deeper component-level customization (swapping tubes/transformers) and proprietary Amp Match tech. However, Cubasis 3 is a full DAW with higher update velocity and better AUv3 stability, making it a more robust choice for end-to-end song production.
Does BIAS AMP 2 support AUv3 in GarageBand?
No. Users report that BIAS AMP 2 lacks AUv3 support, which prevents it from loading as a standard plugin in GarageBand. It relies on older Inter-App Audio and Audiobus protocols, which users find increasingly unreliable.
