Xenobyte

The only reason to use this synth is the challenge of "make at least one good sounding preset". And it's a very, very hard challenge. This synth is called for some people the worst synth for a reason. It can easily compete for the title of worst commercial synth (if there was such a category) - right next to "4G Multi Synth" (by Produce-RNB; I don't know which one is worse).
