What it is

Synthesizer V Studio 2 Pro supports English, Japanese, Mandarin, Cantonese, Korean, and Spanish. Cross-lingual synthesis lets any voice sing in a non-native language. The current version renders at 300% faster speed than v1, requires no GPU, and includes 16-voice polyphonic choir synthesis. Works standalone on Windows, Mac, and Linux, and as a VST/AU/ARA2 plugin inside any major DAW.

Key capabilities

Piano roll vocal editor

Input melodies and lyrics via a piano roll interface. Fine-tune pitch curves, tension, breathiness, vibrato, and phoneme timing note-by-note.

Muse-level AI naturalness

Synthesizer V Studio 2’s AI engine achieves human-level naturalness ratings in blind listening tests — the highest benchmark in the singing synthesizer category.

Cross-lingual synthesis

Any voice can sing in a non-native language. A Japanese voice can sing in English or Mandarin with appropriate lyrics.

16-voice choir synthesis

New in 2026: create polyphonic choirs of up to 16 voices with a single track. Spacing parameter for stereo separation without manual panning.

DAW plugin integration

Works as a VST3/AU plugin with ARA2 integration for tight coupling inside Logic Pro, Ableton, Cubase, and other major DAWs.

MIDI and MusicXML import

Import MIDI or MusicXML files with lyric data preserved. Preserves note-to-lyric alignment from score data automatically.

Ethics assessment — summary

Synthesizer V has one of the strongest ethical foundations in AI audio tools. Dreamtonics works directly with real singers — hiring and recording professional vocalists and licensed voices — then uses machine learning to create the AI models. Consent is documented and singers are compensated. This is a meaningful ethical contrast to tools that train on scraped recordings without explicit consent. The one-time purchase model also means no ongoing financial lock-in. No documented harm events. The choir synthesis update (2026) was built using complete choir recordings with full consent from all participating singers.

Who it’s for

Music producers needing demo vocalsStudio 2 Pro is the standard tool for the category. More natural output than general AI tools and purpose-built for music production workflows.

Film and game composersOrchestral and multilingual capability makes it well-suited for scoring original compositions with sung elements.

Songwriters without access to a vocalistDraft and develop vocal melodies with realistic rendering before hiring a vocalist for final recording.

Producers who want ethical AI voice toolsDocumented consent and singer compensation makes Synthesizer V one of the few AI voice tools with a verifiable ethical sourcing model.

QUESTIONS

Does Synthesizer V require a subscription?

No. Synthesizer V uses a one-time purchase model. Studio 2 Pro is $99 and includes one voice. Additional voices are $79 each. There is no monthly or annual subscription fee and no usage limits after purchase.

Are the voices based on real singers?

Yes. Dreamtonics records real professional singers with documented consent and licensing agreements, then uses machine learning to create the AI voice models. This consent-based model is explicitly documented and represents one of the stronger ethical standards in AI vocal synthesis.

What languages does Synthesizer V support?

English, Japanese, Mandarin Chinese, Cantonese, Korean, and Spanish. Cross-lingual synthesis lets any voice sing in a non-native language — a Japanese voice can sing in English, for example.

How does Synthesizer V compare to Vocaloid?

Synthesizer V Studio 2 Pro produces significantly more natural-sounding vocals than Vocaloid 6 in current comparisons. Vocaloid has a larger legacy catalogue of voice banks and a deeper established community, particularly in Japan. Synthesizer V has better English language quality and more modern AI synthesis. For new projects in 2026, Synthesizer V is the recommended starting point over Vocaloid.
