Best Prompt Phrases for AI Mix Revisions — Mix AI Tips | Free Trial

Make prompts specific and measurable

Replace “make it better” with a target you could A/B: raise lead vocal by about 1 dB in the chorus, tighten kick and bass overlap below 120 Hz, reduce harshness between 2 and 5 kHz on the vocal. If you cannot describe the change in a number, a region, or a section, the mix engine has to guess.

If you want punch, name the element: “more transient punch on snare, keep hats from getting sharper” is a mix note, while “more energy” is a mood board. For an Afrobeats chorus, say keep shaker transients and do not squash the log drum sustain; for metal, preserve pick attack around 2 to 3 kHz while cutting guitar fizz at 5 to 7 kHz.

Section names matter. A verse that should stay intimate is not the same request as a hook that should compete with streaming pop.

Use reference language tied to outcomes

Say wider hook stacks in the chorus, drier verses for intimacy, or brighter hi-hats but not sharper vocals. That separates tone from timbre. “Like my reference” only works if you also say which part: the snare crack, the vocal distance, or the sub weight.

If you want dynamics back, ask for less dense saturation on drums or more dynamic range in the drop rather than “louder drops.” Streaming will normalize anyway. A drill drop that pumps 4 dB on every kick will feel smaller after loudness matching than a drop with a readable transient.

Genre words help when they describe density: stacked pop doubles, dry trap verse, wet 80s pop hall on the last hook only. Mood words like cinematic without a section or a wet/dry target still leave the mix guessing.

One objective per pass beats ten at once

Stacking ten simultaneous requests creates unpredictable interactions. A tight vocal polish pass followed by a drum punch pass is easier to judge. If you ask for more bass, more air, less reverb, wider synths, and a drier rap in one sentence, you will not know which knob moved.

When results are close, switch to micro language: a hair less reverb, slightly tighter compression, a touch more air above 10 kHz. Those phrases map to small moves. Save the novel-length prompt for the first pass only if the mix is clearly in the wrong neighborhood.

If a pass made the vocal perfect and the drums worse, revert the drum part of the request instead of starting over. Keep the win, then send a drum-only note so you do not trade problems.

Examples you can copy verbatim

Use these as written, then swap the section name. They are designed for Josh in MegaMix AI after the first automatic balance.

Keep the lead centered. If you ask for width on “the vocals,” doubles and adlibs may get as wide as a chorus pad, and the lyric will smear on a phone speaker.

• Reduce masking between lead vocal and pad in the pre-chorus; cut pad energy around 400 to 800 Hz, keep vocal presence.
• Add subtle width to doubles only; keep lead vocal centered and upfront.
• Shorten bass sustain under the kick pattern; control boom below 80 Hz without thinning the 100 to 200 Hz body.
• De-ess the lead between 6 and 8 kHz; preserve air above 10 kHz.
• Make verse vocal 1 dB quieter and drier than the chorus; keep the hook stacked and slightly wetter.
• Tighten snare transient; reduce snare ring around 200 Hz if it is washing the 808.

Prompt library by problem type

Keep a note on your phone with the three problems you always have. Most bedroom mixes repeat the same fights: vocal vs guitar, kick vs 808, harsh hats vs sibilance.

Copy the line that matches, then add the section. Do not mix a harshness prompt with a loudness prompt in the same breath.

• Muddy: high-pass non-bass elements around 30 to 40 Hz if rumble is present; reduce 200 to 400 Hz buildup on guitars and pads, not on the vocal body.
• Harsh: reduce 2 to 5 kHz on the offending source; do not darken the whole mix.
• Small chorus: add width to doubles and FX, not to kick, bass, or lead.
• Quiet rap: raise lead 1 to 2 dB and reduce delay wetness; do not smash the bus.

A four-pass revision workflow

Time-box each pass to ten minutes of listening plus one prompt. If you cannot hear a difference, your last request was too small or too contradictory.

Export WAV after each pass if you tend to lose the version you liked. Labels beat memory.

1. Pass 1: vocal level and intelligibility in verse and chorus only.
2. Pass 2: kick, bass, and 808 ownership below 120 Hz.
3. Pass 3: harshness and sibilance on earbuds.
4. Pass 4: chorus width versus verse dryness, then stop.

If pass 4 still needs a rewrite, the arrangement is probably masking the vocal, not the prompt language.

How to prompt Josh in MegaMix AI

Open MegaMix AI, let the AI balance land, then open Josh chat. You do not need a DAW for these revisions. Speak like a mix engineer leaving comments on a bounce, not like you are writing a press release.

Start with: first pass is close; raise lead vocal about 1 dB in the chorus only; keep snare crack; reduce 3 kHz harshness on hats without dulling the vocal air. Export WAV and check a phone speaker. The 7-day free trial is enough to learn which phrases your songs actually respond to.

Need a one-shot transition into the hook? Use MegaSFX AI at /megasfx for a 2 to 12 second sweep, then mix it as its own element instead of asking Josh to “add a riser” that is not in the audio. For the Mix It → Josh → master loop, see the Mix AI hub. Start free trial or See plans.
