PERSONALITY: Mashin is known for his reserved nature, preferring to listen rather than speak out. He enjoys a more quiet and quaint lifestyle as opposed to an exciting one- although he does enjoy the spontaneous every so often. While he appears to be very serious and polite, rumor has it that he'll appear vacant-minded and replicate noises of various animals or devices in the presence of select individuals. He is noted for his "ladylike" personality.

Notable Covers


Voice Configuration


Voice Description: Crisp, mellow, slightly robotic. Tenor.
Recommended Resampler: tn_fnds, bkh01
Recommended Flags: BRE0C10H10P90Y0
Pros- Is crisp and consistent, preferable for both slow and upbeat songs, and has a relatively unique tonal quality.
Cons- His intentional but slightly distorted tone may not appeal to some, and his "de" and "di" syllables have some minor and unfixable frq mapping errors. His accent is notably (but not excessively) and intentionally American sounding to suit his character. Some users may not prefer this sort of sound.

ACT2 [CV] - A beta version of this bank is available for trial usage. Uploads of covers using this bank are permitted, so long as information is provided specifying that the beta version of the bank was used. DOWNLOAD ACT2β

Voice Description: Light, gentle, tenor, slightly rhaspy.
Recommended Resampler: fresamp
Recommended Flags: BRE0C10H10P90Y0g+3
Pros- Smooth and even-toned, this bank does well with soft and slow songs, but can also handle well with quicker tempos.
Cons- He sounds somewhat metallic or rhaspy on particular syllables, and his "to" sample requires rerecording.



Vociferation is an independent horror game using RPGMaker VX Ace as its engine, and featuring Mashin as its protagonist. The game features a number of UTAU and Vocaloid mascots in its cast. Its progress is currently postponed, but is to resume production after the completion of Spiralbound, another game by Machine.
