ACE Studio
ACE Studio is a desktop AI music workspace that turns MIDI and lyrics into expressive sung vocals. It also generates AI instruments, clones voices, splits stems and scores video, with royalty-free output for commercial release.
What is ACE Studio?
ACE Studio is a desktop music production application for Windows and macOS, published by TIMEDOMAIN, INC. Its core is a singing voice synthesis engine the company built from scratch after concluding that vocal sample libraries sounded robotic: you supply MIDI notes and lyrics, and the engine renders a sung performance you can shape phoneme by phoneme, adjusting pitch, vibrato, breath and tension. The library advertises 140+ AI voices across eight singing languages, and the pricing page counts 160+ royalty-free pre-made voices and 40+ AI instruments. Around that engine sits a fuller workspace. Choir Mode assembles pop, gospel, children's or opera choirs by dragging voices onto a track. Voice Cloning trains a model on your own samples, thirty to a hundred minutes of singing or speech being the recommended input, with training taking a few hours. Voice Changer converts a recorded performance into another timbre or an instrumental sound. AI Instruments generate performances from MIDI alone, with an Ensemble mode and string sections recorded with the Budapest Art Orchestra. Generative Kits add Inspire Me, Add a Layer and Music Enhancer, while Video Composer analyses a video scene by scene, writes music that fits it and places sound effects along the timeline. Stem Splitter, Vocal Remover, Vocal to MIDI and a set of browser tools round out the range. The product is built to sit inside an existing workflow rather than replace it. The ACE Bridge 2 plugin loads as a VST3, AU or AAX instrument, with documented setups for Logic Pro, Cubase, Studio One and Reaper and tempo sync through ARA. An experimental MCP server and command-line tool ship with the application, letting assistants such as Claude or ChatGPT inspect and edit a project. AI rendering runs in the cloud, so a powerful machine is not required, but an internet connection is. ACE Studio positions itself explicitly against one-click song generators: it produces neither complete tracks nor instrumental arrangements, and it does no text-to-speech. The vendor states that its voices are trained on licensed recordings and that contributing artists receive a share of the revenue.

When to use ACE Studio / When not to
A quick filter to help you decide if ACE Studio is the right fit.
When to use ACE Studio
- Music producers who need guide vocals, harmonies or full choirs without booking a session singer
- Composers working from MIDI who want note-level control over pitch, vibrato and phrasing
- DAW users who want to drive AI vocals and instruments from Logic Pro, Cubase, Studio One or Reaper through the ACE Bridge 2 plugin
- Video creators and sound designers who need music and sound effects matched to picture
- Artists who want to clone their own voice and keep full ownership of the resulting model
When not to use ACE Studio
- Anyone looking for text-to-speech or spoken voice-over: ACE Studio synthesises singing only
- Users expecting a one-click song generator, since you must supply the MIDI and the lyrics yourself
- Developers who need an API, as none has been publicly released
- People who work from a phone or tablet, because there is no iOS or Android application
- Teams with data-residency requirements outside the United States, where all data is hosted

Pricing & Plans
ACE Studio does not clearly advertise a permanent free plan. Its help centre states that a membership is required to access the software's features, obtained through a subscription, a one-time purchase or a voucher code, although a set of browser-based music tools is available at no charge. The lowest paid entry point shown on the pricing page on 8 September 2026 is the Artist plan at USD 16.58 per month, billed annually. That figure includes a time-limited 20 per cent seasonal discount applied to a USD 20.73 list price. A 7-day money-back guarantee applies to purchases.

Data, GDPR & hosting
A consolidated view of how ACE Studio handles your data.
GDPR overview
The word GDPR appears nowhere on the site, so no compliance claim is made in so many words. The privacy policy nevertheless runs on European machinery: a purpose-by-purpose table of legal bases, rights of access, rectification, erasure, restriction, objection and portability, withdrawal of consent, and the right to complain to a supervisory authority. Transfers out of Europe rely on adequacy decisions, contractual safeguards, the EU-U.S. Data Privacy Framework or binding corporate rules. A Data Protection Officer is designated and reachable at support@acestudio.ai. The gaps are equally visible: no Article 27 EU representative is named, no data processing agreement is published or offered, and no sub-processor list exists.
Who owns the data?
Under the Terms of Service you keep all rights, title and interest in the audio, vocal and musical content you create, and ACE Studio claims no copyright over that output. Custom AI Singers trained on your own recordings belong exclusively to you. You grant the vendor only a limited, non-exclusive, worldwide licence to host, store and process your uploads so the service can run; it may not sell them, sub-licence them, or use them for marketing without your separate consent. That licence ends when you delete the content or close your account, subject to a delay for purging backups, and your rights over output generated during an active subscription survive termination.
Reuse rights
Yes, within limits. Pre-made ACE Studio voices and instruments are royalty-free, so exported vocals, stems and instrument parts can be published, distributed and monetised commercially, including streaming, YouTube, advertising, games and client work, with no extra fee and no attribution required. The terms caution that not every pre-made singer is licence-free, although most are, so the status of each voice is worth checking before release. For a custom voice, your rights depend on whether you own or are authorised to use the recordings it was trained on. One explicit restriction remains: output may not be used to train, fine-tune or improve any AI model that competes with the service.
Data retention & training
Hosting summary
ACE Studio's privacy policy states plainly that the services are hosted in the United States. Using the platform from anywhere else means transferring personal data into the U.S. for storage and processing, and the policy warns that local data protection law may differ from American law. For users in the European Economic Area, the United Kingdom and Switzerland, transfers out of Europe rely on adequacy decisions, contractual safeguards, recipients certified under the EU-U.S. Data Privacy Framework, or binding corporate rules; a copy of the contractual safeguards can be requested from the vendor. No European hosting region and no data residency option are offered. AI rendering is performed in the cloud, although local rendering is also documented. A network lookup on 8 September 2026 resolved the domain to an anycast address on Amazon's AS16509, geolocated in the United States. No hosting or security certification such as SOC 2 or ISO 27001 is published anywhere on the site.

Things to keep in mind
Risks and trade-offs to weigh before adopting ACE Studio.
- Voice cloning is only lawful with the consent of the person whose voice is used, and the terms place that responsibility entirely on you
- A cloned voice may count as biometric data in some jurisdictions, and residents of Illinois are barred from the voice modelling services
- Not every pre-made singer is licence-free, so verify a voice's licence status before releasing a track commercially
- Cloning slots obtained through a subscription lock when that subscription stops, and Generative Kit credits stop refreshing
- Cancelling stops the next billing cycle but triggers no pro-rata refund for the annual period already paid
- The advertised entry price carries a time-limited seasonal discount and will rise once it ends
- Leaning on generated vocals can quietly erode the craft of writing, arranging and directing a real performance
Setup & Integrations
Technical difficulty
Low. Setting up means creating an account, obtaining a membership and running a desktop installer for Windows 10 or 11, or macOS: no server to configure, no code to write. The vendor states that no powerful machine is needed because AI rendering happens in the cloud, and that preset voices, templates and guided workflows let beginners get results quickly. Two steps are more involved: installing the ACE Bridge 2 plugin with the per-DAW settings documented for Logic Pro, Cubase, Studio One and Reaper, and the experimental external agent access, which requires registering an MCP server or CLI.

Should you pick ACE Studio?
ACE Studio occupies a deliberately narrow position in a crowded field. Where most AI music tools race to produce a finished track from a text prompt, this one refuses that shortcut: it hands you a singing engine, a set of AI instruments and a timeline, then expects you to bring the MIDI, the lyrics and the musical judgement. For a producer who needs a guide vocal at two in the morning, a composer who wants a string section without a sample library, or a video editor scoring a cut, that trade is a good one. For anyone hoping to type a sentence and get a song, it is the wrong product entirely. The contractual side is unusually clean. You keep your output and your custom voice models, those rights survive the end of a subscription, and the terms rule out training any model on your content. Voices are described as trained on licensed recordings with a revenue share for the artists involved, which is more than most competitors commit to in writing. Against that, the governance paperwork is thin: no security certification, no data processing agreement, no sub-processor list, no explicit GDPR claim, and all data hosted in the United States with no European option. Commercially, expect some friction. No permanent free plan is clearly advertised, the entry price on display carries a time-limited discount, cancelling refunds nothing pro rata, and cloning slots lock when a subscription lapses. There is no public API and no mobile app. Read the licence status of each pre-made voice before releasing a track, and treat voice cloning as the legally loaded operation it is. Within those limits, ACE Studio is a credible, well-documented production tool rather than a novelty.
