[Catahoulak9]

Unpack the Catahoulak9_Sounds_v3.2 folder somewhere. You should see 5 folders and a readme.txt file.
Copy the 5 folders (or only the ones you want)

Sound_New_20mm_DE&JA_v3.2
Sound_New_20mm_US&GB_v3.2
Sound_New_30cal_v3.2
Sound_New_50cal_v3.2
Sound_New_Hits_v3.2

and paste them in your MODS folder.

DO NOT copy the individual .wav files into your files/samples folder or the .prs files into your files/presets folder.

If you don't like them then you can easily delete them.
