APFX released the Primo 1.5 update in mid-May 2026. Primo users have apparently been asking for a stereo mode, and now they’ve got it.
In January 2025, APFX released version 1.4.0 of Primo. Version 1.4.2 followed in August 2025.
With version 1.5, APFX added two new input modes:
- MIX: Right and left signals are mixed before processing. Designed for lessons or jamming with two guitars into one instance.
- STEREO: Right and left signals are processed separately. Built for maximum width and true stereo tracking.
The update is free for existing users.
