What’s New in FSRAC 4. 1?
In-Game Panel (Great for VR)
A fully integrated MSFS panel gives you direct access to FSRAC without leaving the simulator.
Smart Notification System
Never miss a call again. If ATC, GSX, or any other tool tries to reach you while that channel is muted, FSRAC now displays an on-screen notification inside MSFS to alert you.
Auto-Ducking System with Dynamic Rules
Define smart rules to automatically lower the volume of certain channels when others are active. For example:
- Lower MSFS, cabin announcements, and music when ATC is talking.
- Lower PA audio when GSX is talking.
- Lower PA and MSFS when FS2Crew is active.
You’re in control—define the triggers, the targets, and the ducking intensity with just a few clicks.
