According to the VOCALOID STORE, IA ROCKS began development soon after the original vocal was released and was in development for 2 and a half years. It was built based on the most common complaints users had about the original vocal in an attempt to correct the issues. The vocal was made with an entirely new concept in mind and was made from entirely new recordings. Unlike the original voicebank, Lia found the IA ROCKS vocal to be difficult because her vocal normally lacked power.
At the end of 2013, news began to emerge of a new IA related project that was set to be released some time in spring 2014. This project was revealed to be a new vocal in Japanese with a change of tone. On January 27, 2014, a downloadable demo referred to as "IAα Type C" was released in which 1st PLACE Co., Ltd. requested participation in their feedback campaign from those who wished to take part in helping improve the vocal.
On May 22, it was announced that the official name of the voicebank was IA ROCKS and was due for release on June 27. A PV featuring the voicebank was also released and would be used as the opening for IA Visual Tracks Colorful.
On June 6, the following extras were revealed to be bundled with the software:
- DVD-ROM including IA ROCKS demo songs, instrumentals, VSQXs and LIVEDRIVE(IA ROCKS ver.) MMD Model + Motion Data
- IA ROCKS Guide Book
- Special Sleeve Case
Several packages were released containing the software apart from the regular edition. The duo package contained both IA's original library and IA ROCKS, while a starter bundle contained both voicebanks and the VOCALOID3 editor.
On June 28, 1st Place aired a livestream to celebrate IA ROCKS' release. 12 demos of the voicebank were shown and also included a showcasing of the products in the IA ROCKS package. On July 2, short versions of these demos were uploaded to 1st Place's SoundCloud.
In 2018 upon the release of VOCALOID5 an upgrade offer was given for those who purchased the "IA DAW PACKAGE". This would upgrade the engine side of the package to VOCALOID5, though IA remains a VOCALOID3 vocal.

|Package details as noted:|
A new voicebank for IA with a different tone of voice and is reported as overall a lot less like Lia's vocal herself, as she is not normally a strength vocalist. As the name suggests, this vocal is built for rock songs. According to the details on the VOCALOID store, it was made to counter the issues of the original IA vocal, containing adjustments based on information supplied by feedback from users of the original IA vocal. The vocal was made from new recordings by IA's provider, Lia.
