Not sounds like you're thinking of... I don't think. In fact, I've never seen anything that I thought might be actual custom sound effects except in MM2PTC, and the closest other thing was footsteps in Village and Petit Forest, and I'm pretty sure those were accomplished with instrument or waveform manipulation.

At any rate, the only "sound" creation tool is the "sample program" waveform maker, which should be sample 12.
