Thanks everyone! Sorry for no update, I've been taking a break, but here is what you can expect. 1: The 1m engine sound is getting an overhaul. 2: The 2M engine sound is now going to be the srb sound, from the 3M engine and the SRBS. 3: THe 3m engines are now going to be an F-1 engine sound. 4: Compatibility with "World space" Saturn V 5: Compatibility with B9 aerospace, with each engine (hopefully) having a custom sound!
