[2] Their first product for the software was "Sweet ANN" a VOCALOID2 voicebank and was first introduced at the Musikmesse fair and later released on June 29, 2007.
The boxart of Sweet ANN is based on an edited picture of actress Lena Horne from the theatrical poster of the 1943 film Stormy Weather.
[2] Their second VOCALOID2 "Big Al" was released with the voice provided by former employee Frank S. after the intended provider, Elvis Presley impersonator Michael King, was unable to return for further recordings after their initial samples were considered not at a high enough quality to be released.
OLIVER was developed under Anders Sodergren, the leader of VocaTone, a team of fan-based VOCALOID producers.
VocaTone then had PowerFX release their second VOCALOID3, "YOHIOloid", a bilingual male vocal that is capable of singing in English and Japanese, sampled from Swedish singer Yohio.
