Quoted from DML1001:
So far, here is what I've noticed is different with the pinsound 'default' sound package versus the original board:
-Missing extra ball sound (nothing plays when extra ball is awarded)
-Tire screeching sound that plays on first & second multiball lock (and other spots) is replaced by a different sound. It sounds more like one of the gear shift noises
-Weird ducking issues with some SFX which are classified as stingers (police noise 3 for example)
If you are missing sounds, open the project in pinsound studio. It will give you a list of missing sounds with corresponding numbers after. These numbers represent a folder on the usb drive for each sound missing. When I was remaking the Sega Frankenstein audio I had the same issues, missing sounds that I knew was supposed to be there. I contacted pinsound via Facebook messenger, sent them the list of missing files, and they sent me a list of foldernames to put the missing sounds in.
Now, you can't just create a folder with the missing file number yourself and put it on the corresponding category folder. That won't work. They have some sort of algorithm to define the actual foldernames. I guess it a secret of the trade.
