History

On February 13, 2025, Dreamtonics opened pre-orders for Synthesizer V Studio 2 on its international store, as well as pre-orders for Synthesizer V 2 AI versions of all of its signature voice databases, including Riku 2. Also, a limited-period campaign was launched that would allow current owners of Dreamtonics' Synthesizer V AI voice databases (like Riku) to upgrade them to their Synthesizer V 2 AI versions at deep discounts.

Riku 2 was released on March 21 as expected.

Package details as noted:

This is the Synthesizer V Studio 2 version of Riku, a masculine Japanese vocal. As an AI vocal, this enables him to sound realistic and human-like.

Vocal traits as noted:

• Riku 2's voice was described as having a sensitive, crisp yet brittle-sounding male tenor voice; creating a soft, soporific impression on the listener, with a whispery, feather-like tone.
• He was noted to be suitable for low-mid tempo, gentle, warm emotional and romantic J-pop, K-pop, soul, electronic music.
• He was noted to have a slightly exotic accent, with a not atypically Japanese-sounding voice.
• Riku 2 is able to sing more realistically through changes in volume and breath, further enriching singing details, making each singing unique, and providing creators with more options. Through this mode, he can use AI Retakes to create multiple "takes" of a sung section to find an ideal vocal without the need for "laborious tuning". This feature is only available in the Synthesizer V Studio 2 Pro Editor.

Phonetic notes as noted:

• Phonetic format: Romaji
• Through Cross-lingual Singing Synthesis, Riku 2 can sing in not only Japanese but also in English, Mandarin Chinese, Cantonese Chinese, Spanish, and Korean. This feature is only available in the Synthesizer V Studio 2 Pro Editor.

Vocal Modes as noted (Synthesizer V Studio 2 Pro Editor only):

Riku 2 comes with three variations within the Vocal Mode function:

• "Soft"
• "Warm"
• "Powerful"
