A lot of the current musicians out there (WoodenToaster, The Living Tombstone, etc) have pony voices in their songs. I'm just wondering if anyone could tell what kind of program I would need to get, or techniques I'd have to learn to be able to edit pony voices into my songs.
I don't mean just importing samples, I've got that down, haha

If anyone can help me out, that'd be great! Thanks!
