You can hear complete cockpit ambience with some switches, full GPWS test included.
It will sound exactly the same in the simulator, the mixdown has been set up that way.
Release date? No release date at the moment, we are still searching for alternative ways to get the proper recordings of some crucial sounds we are missing to finish the soundpack. Considering the current situation, we can't tell when we will get new recordings, or at all since MD80 is an endangered species now.
More info hopefully soon, fingers crossed!

It will be installed into "737NG CFM Immersion Soundpack V2 (v2.1)" folder by default, so it is not mandatory to remove previous version.

Changelog:

- added support for PMDG NGXu sound engine:
   (engine whine volume depends on altitude)
   (engine buzz sound and volume depends on altitude)
- adjusted volume of APU, fuel and hydraulic pump sounds
- tweaked some values in sound.cfg
- improved and updated Quick User Guide

​

We are preparing a very important update for CFM V2 soundpack, and it will be interesting only for NGXu users. Now the engine sounds will properly use built in sound engine in the NGXu.

That simply means - engine sounds will sound different on takeoff and for example on FL150, especially engine buzz. On FL350 you will not hear the engine whine/buzz at all, but you can still somewhat hear low frequencies (bass). Sounds really nice and much more realistic.

We completely overlooked this feature before the initial release, our apologies.

At the moment we have some problems building the installer, and as soon we find the proper solution, the update will be live and it will be followed by a demonstration video.

Safe flights!

Please make sure you are logged in to grab it for free if you are already a 737NG CFM Immersion Soundpack HD customer!

Also, please note that 737NG CFM Immersion Soundpack HD is no longer available for purchase.
It's not supported anymore, and its best to avoid any confusion regarding both products.

​Happy flights!

While we are finalising the preparations for a release, sit back, play the preview and enjoy the purest sounds and frequencies of CFM56 engine whine.
We strongly believe this is the most authentic CFM56 soundpack to date, and a true successor to the first version.

Release is expected in the next 72hrs, fingers crossed!

NOTE: the volume of the engine sounds is deliberately raised a bit for demonstration purposes!

We decided to release new CFM soundpack update as a completely new and separate soundpack - 𝟳𝟯𝟳𝗡𝗚 𝗖𝗙𝗠 𝗜𝗺𝗺𝗲𝗿𝘀𝗶𝗼𝗻 𝗦𝗼𝘂𝗻𝗱𝗽𝗮𝗰𝗸 𝗩𝟮. All internal engine sounds are completely redone and enhanced, 𝗡𝗚𝗫𝘂 𝗰𝗼𝗺𝗽𝗮𝘁𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗶𝘀 𝗮𝗱𝗱𝗲𝗱.

​We believe releasing the update as a new product is a good idea, simpler for customers to separate - V1 (old one) is compatible with NGX only, V2 with NGXu and NGX.

Most important thing - for current 737NG CFM Immersion Soundpack HD customers, 737NG CFM Immersion Soundpack V2 will be 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲𝗹𝘆 𝗙𝗥𝗘𝗘.
​
The release is expected during next week.

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.

As we promised on our Facebook page, here is the "short" preview teaser of the Maddog X Cockpit Sound Immersion, just to show you the quality and authenticity we are aiming for.

𝗔𝗹𝗹 𝘁𝗵𝗲 𝘀𝗼𝘂𝗻𝗱𝘀 𝘆𝗼𝘂 𝘄𝗶𝗹𝗹 𝗵𝗲𝗮𝗿 𝗮𝗿𝗲 𝗪𝗼𝗿𝗸 𝗜𝗻 𝗣𝗿𝗼𝗴𝗿𝗲𝘀𝘀 (𝗪𝗜𝗣), 𝗲𝘀𝗽𝗲𝗰𝗶𝗮𝗹𝗹𝘆 𝘀𝘄𝗶𝘁𝗰𝗵𝗲𝘀 𝗮𝗻𝗱 𝘃𝗼𝗹𝘂𝗺𝗲 𝗯𝗮𝗹𝗮𝗻𝗰𝗲𝘀, 𝗮𝘀 𝘄𝗲 𝗮𝗿𝗲 𝗰𝗼𝗻𝘀𝘁𝗮𝗻𝘁𝗹𝘆 𝗴𝗲𝘁𝘁𝗶𝗻𝗴 𝘁𝗵𝗲 𝗳𝗲𝗲𝗱𝗯𝗮𝗰𝗸 𝗳𝗿𝗼𝗺 𝘁𝗵𝗲 𝗠𝗗𝟴𝟬 𝗽𝗶𝗹𝗼𝘁𝘀.
​
ETA? We are still planning to release it until the end of this month (or year if you prefer), but no promises. Our main focus is quality/authenticity, and we will delay it to January if needed/or until the pilots show us a green light.
