Not my usual content, but I wanted to share regardless.
I wanted to test other voices and I couldn't find what I needed, so I made it. Does exactly what it says, swaps all voices to all voice numbers individually.
NOTE: I recommend ticking all the boxes for all the voices within the mod, some just don't work without this.
Penumbra is needed, file format is .pmp Zipped folder contains 12 .pmp's for each voice individually.
