Synthesizer V Studio 1.8.1b1 Update

Synthesizer V Studio 1.8.1b1 introduces new features and improvements aimed at making voice synthesis even more flexible and intuitive. The update includes:

  • Integration of Vocal Mode into the Parameter Panel for dynamic modulation of voice timbre (Pro edition required).
  • Improved neural vocoder for male vocals, resulting in enhanced sound quality in the bass range.
  • Updates to the available masculine AI voice databases to fully utilize the new capabilities of the neural vocoder.


Make sure to update both the Synthesizer V Studio editor and the voice database to the latest version to access these new features.

Integration of Vocal Mode into the Parameter Panel

We are pleased to announce the integration of Vocal Modes into the Parameter Panel in Synthesizer V Studio Pro version 1.8.1. First introduced in the 1.6.0 update, Vocal Modes allow users to adjust the voice timbre to match the mood and genre of their songs. We have since then updated the lineup of AI voice databases to include an expanding set of Vocal Modes.


With the integration of Vocal Modes into the Parameter Panel, users can now dynamically modulate the effect of each Vocal Mode. This provides greater control over the vocal performance, allowing users to emulate the gradual shift of emotions throughout a song. The integration follows the automation feature found in many DAW software, giving producers familiar and intuitive control over their vocal production.




Synthesizer V Studio 1.8.1 introduces a redesign of the Parameter Panel with the parameters, including Vocal Modes shown in absolute values. The new design displays the global value set in the Voice Panel as a base level, with the ability for users to set parameters as offsets. This change enhances the connection and consistency between the Voice Panel and Parameter Panel, offering a more intuitive experience. The upgrade is fully compatible with existing projects and requires no action on the part of the user.




Improved Neural Vocoder for Male Vocals

Synthesizer V Studio version 1.8.1 features algorithmic improvements to the neural vocoder, a key component of the AI synthesis process. This results in enhanced sound quality in the lower vocal range of male vocals, with reduced noise and a more stable timbre. Producers can now reach deeper in with their works without worrying about quality loss.

Voice Database Updates

Along with the algorithmic improvements to the neural vocoder, Synthesizer V Studio 1.8.1 also comes with updates to the available masculine voice databases. To fully utilize the new capabilities, make sure to update both the Synthesizer V Studio editor and the voice database to the latest version. The updated voice databases are listed in the following table.
