ACE Music is a song generator from ACE Studio, the company behind the ACE Studio vocal-synthesis DAW and co-developer of the open-source ACE-Step model. It runs its own closed model, ACE Music v1, which on November 11, 2026 took the top spot on Artificial Analysis' blind vocal leaderboard, just ahead of Suno v6 (Elo 1,160 vs 1,144, with overlapping confidence intervals, so call it a tie). That's why "Suno vs ACE Studio" started showing up in searches, and why it's worth a straight comparison.
As on every comparison here, we compare plans, terms and features from each company's own pages, checked on the date at the top. We don't rank them by sound: blind leaderboards move with every release, and which one suits you depends on your genre and your prompt. Try both free tiers on the same lyrics.
Where ACE Music is different
Downloads aren't capped on paid plans. ACE Music's Creator plan ($7.90 a month billed yearly) and Artist plan ($16.58) both include unlimited downloads, a stem splitter and commercial use rights, with up to 500 and 1,250 songs a month. Suno Pro allows 20 downloaded songs a month and Premier 60, and on Suno the download is what gives you commercial rights. If you make a lot of keepers, that's the biggest practical difference.
It starts from a melody, not just a prompt. Besides text and lyrics, ACE Music takes a hummed recording, notes played on an on-screen keyboard, a MIDI file or a score, an image or a video, a song to cover, or two songs to mash up. Its v1.1 preview model plans the music as a score first, and you can turn a song into MIDI and open it in your DAW. Suno added MIDI input in November 2026, on Pro and Premier.
A free open model sits beside the paid one. The free plan gives 20 credits a day, enough for about 10 songs on ACE Music v1, with no downloads and no commercial rights for those. It also includes ACE-Step v1.5 with no limits: unlimited generations and free MP3 downloads, commercial use included, whether or not you ever pay. ACE-Step is open source under the MIT licence, so you can also run it yourself (see Suno vs ACE-Step). Suno's free plan is v6-mini only, with no monthly downloads.
Artist includes a full DAW. The Artist plan adds ACE Studio itself: AI vocals and instruments, VST3 and AU plugins, voice cloning and a music-video tool. Suno's equivalent is Studio, on Premier ($24 a month billed yearly).
Where Suno is different
Editing inside the generator. Suno v6 runs up to eight minutes a generation and gives you Extend, Replace Section, Cover, Remix, stems and, on Premier, Studio. ACE Music doesn't publish a maximum song length.
Custom models and voices. Suno can fine-tune v6 on your own tracks and use your own voice on paid plans. ACE Music's voice cloning comes with the Artist plan's DAW.
A prompt format with tools around it. Suno reads a Styles field, lyrics with cued section headers and an Exclude list. There's a whole ecosystem of guides and tools for it, ours included: the v6 prompt guide, the free Styles checker and the lyric checker.
Training data. Suno says v6 was trained on licensed Warner, BMG and Believe material, and it faces lawsuits from Universal and Sony among others. ACE Music doesn't say what its own models were trained on. Its terms, effective November 1, 2026, let it train future models on content users submit from that date.

Taking a Suno prompt to ACE Music
The biggest trap is parentheses. In Suno, words in parentheses in the lyrics are usually sung, as backing vocals or echoes. ACE Music reads parentheses as performance directions, like "hum softly" or "add guitar here". Paste a Suno lyric sheet as it is and your backing-vocal lines may be read as instructions instead.
- Lyrics: keep the section headers (
[Verse 1],[Chorus]). Move delivery notes (whispered,belted) into parentheses where they should apply, and turn sung parenthetical echoes into ordinary lines, or drop them. - Style: a Suno Styles field (genre and tempo, era, vocal, drums, bass, the hero part, the arc) is a good starting style prompt as it stands.
- Exclude: ACE Music doesn't document a negative field, so leave the list out rather than writing "no trap hi-hats" into the prompt.
We haven't run a listening test of converted Suno prompts on ACE Music yet, so treat your first takes as a test.
The bottom line
If Suno's download cap is what's holding you back, or you like to start from a melody you hummed or wrote, ACE Music is the strongest new option to try, and its free tier lets you test both its own model and ACE-Step without paying. If you rely on Suno's editing, longer songs or a custom model of your sound, Suno is still the more complete studio. Plenty of people will use both.
