Vypyr X

Aside from connectivity issues, this app lacks any functionality that would actually make it worthwhile. You really would think that they could show you what parameters you're editing with the effects, but apparently Peavey thinks that because they can't fit the text all at once on the top of an amp, they also can't fit it on a phone screen that can scroll through an infinite number of different views, and that they need to just put "P1" and "P2" for every effect. Also no access to any extra parameters like the noise gate or anything else not already controllable from the amp. Doesn't even give nice preset editing. Made by someone who was trusted with basic instructions, and then tried to do less than the very minimum.

Connected the app to the amp and the amp immediately went dead
