Decay and Loudness set to 1 is pretty much dry sound only. Change the sliders to mess with the reverb. You don't need the variables, but I put them there for show. Look inside at the notes for how to make the reverb work properly. The reverb can be use in a lot of different ways. The right amount of reverb can make any atmoshpere creepy - or something. GIVE CREDIT WHERE CREDIT WHERE CREDIT IS DUE! You can remix. I pretty much got the reverb impulse, trimmed it, and made it easily customizable.
Reverb samples by Image-Line. I got the sounds from FL Studio 11 in the impulses folder, and then re-rendered it as an mp3 using Edison so scratch can read it.
