Piapro Studio is a software snthiser create by Crypton Future Media, Inc.
Piapro Studio was created to allow the developers to expand their VOCALOID characters in new directions that VOCALOID limited within its software. It was originally sold as an alternative to supplying the full VOCALOID software and was first released with Kaito and the "KAITO V3" software.
Piapro Studio was first released with KAITO V3. It was originally supplied as an alternative to VOCALOID3 and allowed the use of KAITOs voicebanks without the need to own VOCALOID3 in addition to the release of his software.
It used the VOCALOID3 API as its means of synthesising results.
Piapro Studio 2
Piapro Studio 2 was released in conjunction to the VOCALOID4 update. It was first released with Megurine Luka V4x.
It used the VOCALOID4 API as its means of synthesising results.
Piapro Studio encountered problems when VOCALOID5 was released. While this did not cause Piapro Studio to cease function, it resulted in Piapro Studio results having to be manually entered in VOCALOID5, rather then being in-putting directly and with ease with VOCALOID4.
NEXT Generation Piapro Studio
