Dunder_Mercedonius (Art by Pencil Peach!)


Dunder is the enigmatic head of the Z Music Club. Not much is known about the boy, as it appears all mentions of his identity have been scrubbed from public record. He is often seen wearing an OLED Mask, that typically displays nothing but a question mark.

Dunder very rarely makes on stage appearances, let alone ones in which he sings. Most simply describe his voice as normal or not something they’d commit to memory.

The following voicebanks are currently in development
Dunder_Mercedonius is a “Dark” English ARPA voicebank. It will be released in beta whenever the OTO is finished.
Dunder_Intercalaris is a “Dark” Japanese CVVC voicebank. It will be released whenever the OTO is finished.
Some 1-pitch OpenUTAU compatible voice colors may be included with Intercalaris, if these are released they will also be offered standalone for convenience.


The following voicebanks are discontinued, and there are no plans to bring them back:
Dunder_CV (Dunder_Aki, Dunder_Natsu, Dunder_Haru, Dunder_Fuyu, Dunder_Genesis)
These were a set a 5 CV voicebanks I recorded when I was like 15, the OTO wasn’t the best and as I was a minor when they were recorded, it was ultimately for the best to discontinue them.
This was just a set of me saying phrases for use in song, as with Dunder_CV, I was 15, but also I was REALLY bad at voice acting so the samples were also just bad.


Mercedonius 8% Test

Publicly released test of Dunder_Mercedonius. This voicebank is far from complete, and we suspect it may end up needing to be fully rerecorded sometime after release.
Regardless, this video should give you a decent idea of what Dunder’s English voicebank will sound like tone wise.
Not shown in this video is an experimental Whisper append that may or may not get scrapped.
