Question re: startup sound

Hi all, I love the new sounds, it really reinvigorates the 744! Have tried the GE and RR sets, and will try some PW noise out tonight. :9One question though, from what I can see, it appears that the startup sound is derived solely from the gradually increasing N1%, am I correct?The sound.cfg file points to a file that has no noise in it, so what we hear in the sim must presumably not have anything to do with this sound.The reason I ask is that I want to drop in a sound file for my own purposes that adds the low frequency 'hum' you get inside an aircraft as lightoff occurs and the engine spools up.Armen, if you were prepared to do so, could you please provide me with some pointers on how to do this? I am aware that support isn't offered for such mods, I just want to try it out to see if it adds something for my own tastes. if you are unwilling or unable to assist I completely understand.You can PM me if you wish to take if off the forum.Thanks,Mark
