VoiSona Song

VoiSona Song is singing-voice synthesis software for composers and producers who want to build vocal parts from notes and lyrics. It suits people who want detailed control over a synthesized performance and the option to work on desktop or iOS. Its strongest case is flexible score entry and vocal editing; its free editor is limited to a 10-second preview.

Overview

VoiSona turns a written vocal part into synthesized singing. You can enter notes in a piano roll and assign lyrics, import MIDI into a DAW, or upload MusicXML. That makes it workable both for people composing in the editor and for producers bringing an existing arrangement into a vocal workflow.

Once a part is entered, controls for phoneme timing, pitch, volume, vibrato, voice quality, and huskiness allow adjustments beyond note placement. This is a better fit for users who want to shape how a line is performed than for those seeking a one-click finished song. Commercial use is allowed.

Key features

The PC app runs standalone or as a VSTi or Audio Units plug-in. The iOS/iPadOS app also runs standalone, or as an AUv3 plug-in compatible with GarageBand, Logic Pro, Cubasis, and more. That gives users a choice between composing within VoiSona and fitting it into supported DAW workflows.

Exports include WAV, MIDI, MusicXML, CCS, CCST, tsmsln, tssprj, and Lab. WAV supports audio delivery, while MIDI and MusicXML can carry score material into other workflows. The additional project and data formats may be useful in compatible setups, though their presence alone does not establish compatibility with every other application.

Voice choice is an important constraint: CeVIO Creative Studio and CeVIO AI exclusive voice libraries cannot currently be used with VoiSona. Existing owners of those libraries should not choose it on the assumption that their purchases will transfer.

Pricing

The free editor and Chis-A library make it possible to start without a purchase, but the 10-second cap confines the editor to previewing a vocal rather than completing a full-length song. Paid libraries are the relevant choice for longer work, with monthly, annual, and outright purchase options. Since the price depends on the library, compare the specific voice and term before committing.

Completed purchases cannot be refunded. Automatic subscription renewal can be cancelled during the subscription period, so subscribers should manage renewal before the next billing period if they do not want to continue.

Platforms

VoiSona is available for Windows, macOS, and iOS/iPadOS. The PC download page specifies Windows 10 64-bit version 22H2 or later, Windows 11, or macOS Big Sur 11 through Tahoe 26, with at least 4 GB RAM and 1 GB of free disk space. An internet connection is required for installation and some features, and sign-up is required.

Who it's for

VoiSona is most compelling for composers and producers who already work with scores or DAWs and want adjustable synthesized vocals, including on iOS. The free Chis-A library offers a no-cost starting point, while paid libraries are needed to move beyond the short preview. It is a poor fit for anyone relying on CeVIO-exclusive libraries or needing unrestricted full-song output without purchasing a voice.

Pros and cons

Pros

• Multiple score-entry routes: piano-roll lyric entry, MIDI import, and MusicXML upload serve both in-editor composition and existing score workflows.
• Performance controls: phoneme timing and voice-quality adjustments give users more ways to refine a vocal than note entry alone.
• Desktop and iOS DAW integration: standalone use and plug-in options offer flexibility across supported workflows.
• Free starting point: the editor and default Chis-A singer cost nothing, and commercial use is allowed.

Cons

• Short free preview: the editor sings only the first 10 seconds before a voice library is purchased, limiting free use for complete songs.
• Library incompatibility: CeVIO Creative Studio and CeVIO AI exclusive libraries cannot be brought into VoiSona.
• Purchase commitment: completed purchases are non-refundable, so selecting a paid library warrants care.
• Account and internet requirements: sign-up is mandatory, and some features plus installation need an internet connection.

Alternatives

For a broader comparison, see AI Singing Voice Generators. Choose Revocalize AI if its free plan's 5 conversion minutes per month and one Starter AI voice suit your needs better than VoiSona's score-centered editor and 10-second preview. NEUTRINO is a free alternative for general music and audio production, though system integration or embedding generated audio in an application requires separate permission.

Kits AI offers a free plan with 15 conversion minutes, voice designer/blender, and generative vocals, but no voice slots or download minutes; choose it if those conversion-oriented tools fit your workflow. SoulX-Singer is another free option, with code and model weights available to researchers and developers under Apache 2.0.

Audimee may suit users who want a web-based conversion service: its free plan includes 15 conversion minutes, 11 royalty-free voices, MP3 downloads, and personal use only, with no custom voice slots or Harmony Maker. LyricToMelody AI is worth considering for lyric-first draft generation; its free Starter plan includes 20 credits, MP3/WAV/PCM export, and seven-day project retention.

SightSinger is a web-based alternative. Sinsy offers free online synthesis by uploading a MusicXML score, making it a simpler option for users who want that score-to-vocal route.

Verdict

Choose VoiSona Song if you want to compose or import scored vocal parts, refine the synthesized performance, and work standalone or inside supported desktop and iOS DAWs. The free editor and Chis-A singer are useful for a first look, but the 10-second limit makes a paid voice library necessary for full-length work. Look elsewhere if you depend on CeVIO-exclusive libraries or want complete free-song output.
