I'm working in 737-800 full flight simulator. It's not certified by Boeing, using X-Plane with some custom plugins for physics and graphics and Project Magenta for cockpit systems. But I'm not satisfied with Project Magenta sound system and want to use FlightGear as system for engine sound. So I have one computer, where is main copy of X-Plane with XPUIPC plugin. On Project Magenta there is XPWideClient, which receives data from X-Plane. System - Windows 7.
And here is question, which I don't know the answer: can I read some properties via Nasal or another way? I need just N1 for every engine for sound.
