We are finishing the tests of 𝟳𝟯𝟳𝗡𝗚 𝗖𝗙𝗠 𝗜𝗺𝗺𝗲𝗿𝘀𝗶𝗼𝗻 𝗦𝗼𝘂𝗻𝗱𝗽𝗮𝗰𝗸 𝗛𝗗 𝘃𝟭.𝟯 that will provide a FULL compatibility with the PMDG NGXu, with other sound enhancements in general.
In the meantime, we decided to make NGX Cockpit Sound Immersion partially compatible with new PMDG addon, while you wait for dedicated soundpack for it. Update will change NGXu sounds of - avionics, packs, trim wheel, shakes, rattles and other ambient noises, as well as warnings/GPWS. Switches, levers and other "clicky" stuff will remain untouched for a simple reason - it demands a lot of work. As you probably know, we will record completely new set of sounds for the NGXu and release it as a dedicated Cockpit Sound Immersion in 2020.
