ACE Studio review

ACE Studio is a desktop music workstation built around AI singing voices and instrument tracks. It turns MIDI melodies and lyrics into vocal performances that you can edit, including pitch, dynamics, breath, vibrato, and vocal tension. You can also convert MIDI into audio using its virtual and acoustic instruments.

The vocal tools include a library of more than 160 royalty-free voices in multiple languages, VoiceMix for blending existing profiles, and voice cloning from uploaded recordings. Production tools listed for ACE Studio include stem splitting, vocal-to-MIDI conversion, lyrics transcription, and PDF-to-MusicXML conversion.

That makes it a different kind of purchase from a prompt-first song generator: its stated workflow centers on working with MIDI, lyrics, voices, and production tools inside a desktop workstation. The free tier offers a way to try some of those tools, but access is limited.

The appeal is range. ACE Studio combines vocal synthesis and editing with instruments and utility tools, so a creator can work on a vocal line, generate instrument audio from MIDI, and handle tasks such as stem splitting or vocal-to-MIDI conversion in the same product. The listed voice library has more than 160 royalty-free voices, while the instrument selection includes more than 40 royalty-free options.

VoiceMix may suit creators who want a voice between existing profiles without training a custom model. For users who do want custom voices, the paid plans include cloning slots: Artist lists one vocal synth slot and one vocal changer slot; Artist Pro lists five and 10, respectively.

The pricing page lists a free tier with 100 monthly credits, though unused credits clear each month and tool and voice access is limited. Artist is listed at $16.58 per month and Artist Pro at $22 per month as annual monthly equivalents. The pricing information says those rates are billed yearly for two years, with access forever. A Reddit user also describes the core voice tools as distinct from cloud-based generative features, though that distinction is not confirmed on the vendor's site.

The headline prices need context. The $16.58 Artist and $22 Artist Pro figures are annual monthly equivalents, not published month-to-month rates. The pricing information says they are billed yearly for two years and include access forever; it does not publish a separate monthly price. Enterprise team pricing is not published either. That makes it harder to compare the actual upfront commitment with a monthly subscription.

Credits and cloning slots are also capped by plan. Free includes 100 monthly credits, and unused credits clear monthly. Artist includes 2,500 credits and one slot each for vocal synth and vocal changer cloning. Artist Pro raises those limits to 5,000 credits, five vocal synth slots, and 10 vocal changer slots. The pricing details do not say how many credits particular tasks use, so the practical reach of each allowance is unclear.

There is also uncertainty around what “access forever” covers. In one Reddit thread, commenters disagree about whether cloud-based generative AI tools require ongoing credits, while some distinguish those tools from core voice synthesis. Treat that discussion as user interpretation, not a definitive license explanation. Before paying for a two-year term, get the current terms for cloud features, activation, and future reinstalls in writing.

ACE Studio has a free tier with 100 monthly credits; unused credits clear each month, and access to tools and voices is limited. The Artist Plan is listed at $16.58 per month and includes 2,500 credits, 160+ voices, 40+ instruments, one vocal synth cloning slot and one vocal changer cloning slot. Artist Pro costs $22 per month and raises the allowance to 5,000 credits, five vocal synth cloning slots and 10 vocal changer cloning slots. That’s a $5.42 monthly-equivalent jump for the higher limits.

The catch: those paid rates are annual monthly equivalents, billed yearly for two years, with access forever. Month-to-month prices are not published. Team plans include shared credits, centralized billing and admin controls, but pricing is not published. No add-ons are listed. Check the billing terms before committing, especially if you need a short-term subscription.

Switching in may mean rebuilding parts of a workflow around ACE Studio’s desktop workstation: it turns MIDI and lyrics into editable vocals and synthesized instruments, and includes tools such as stem splitting and vocal-to-MIDI. Keep original MIDI, lyrics and recordings outside the app until you confirm what your current setup can import and what ACE Studio can export. The published product information does not specify project compatibility, export formats or whether custom cloned voice models can be exported.

Those gaps matter when switching out, too. The available details do not say how projects or trained models transfer to another tool, so check that before building a production process around them. We were not given Reddit posts or comments for this review, so we can’t responsibly attribute reasons for leaving to users. The practical decision is whether ACE Studio’s vocal and instrument tools justify checking those portability terms before you move a project over.
