Installation
Requirements
- •macOS 13 Ventura or later (Apple Silicon recommended)
- •Logic Pro 10.7+ installed
- •A built-in or external microphone (for voice mode — optional)
- •Internet connection (for GPT responses; all Logic Pro automation runs locally)
Step 1 · Download & install
- Click the Download Revocalize Co-Producer button on our website. A
.dmgwill save to your~/Downloadsfolder. - Double-click
Revocalize Co-Producer v0.2.17.dmg. A window opens showing the Revocalize Co-Producer icon next to an Applications folder shortcut. - Drag Revocalize onto the Applications shortcut. Wait ~5 seconds for the copy to finish, then close the window and eject the DMG from your desktop.
Step 2 · Launch the app
Open Applications in Finder and double-click Revocalize.
Step 3 · Approve keychain access
On first launch, macOS will show a keychain prompt asking for your Mac account password. You may see it up to three times in a row — that's normal, each prompt is for a different keychain entry.
Step 4 · Grant Accessibility permission
Revocalize uses macOS Accessibility to drive Logic Pro. Without it, no commands will execute.
- On first launch you'll see a banner inside Revocalize: “Accessibility access required”. Click Open System Settings.
- Return to Revocalize Co-Producer — the banner disappears and the app is ready.
Voice permissions (only if you use voice)
Two more permissions are requested on-the-fly the first time you use voice — you don't need to set them up in advance:
| Permission | When you'll be asked | Why |
|---|---|---|
| Microphone | First time you use voice (mic button, push-to-talk, or wake word) | Captures your voice for transcription |
| Speech Recognition | First time you use voice | Transcribes your voice locally on-device |
You can review or change every permission anytime in System Settings → Privacy & Security.
First-time Setup
Open Settings (sidebar → gear icon) and walk through these panes:
Voice
- •Wake Word — on-device listening so you can summon Revocalize hands-free while producing.
- •Push-to-Talk — hold
Right Option (⌥)to talk; release to send. No wake word needed. - •Text-to-Speech — pick Apple's built-in voices (free, offline) or OpenAI voices (requires API key).
About · Danger Zone
If you ever want a fresh start, Settings → About → Danger Zone → Clear All History & Sessions wipes chat history, command history, and confirmation allowlists. Irreversible.
How You Interact
The Studio tab is your main workspace. You have two equal input channels:
- •Voice — tap the microphone, use push-to-talk, or say the wake word. You'll see a live transcript as you speak.
- •Text — type into the prompt box and hit Return.
Revocalize speaks back using TTS (if enabled) and keeps a conversation history so you can say things like "rename that track to Bass" after creating it.

💬 General Conversation
Revocalize also answers general music-production questions and follows context across a session:
- “What's a good starting tempo for drum & bass?”
- “What tracks did I just create?”
- “Explain what a send is”
MIDI Generation
MIDI Generation turns a sentence into playable parts. Ask for “deep-house drums at 124 with a sub bass and a pluck” and the Co-Producer generates the MIDI, creates a Software Instrument track per part with a meaningful name, and imports each part onto its matching track automatically.
Three ways to use it
- •Generate. A fresh idea from a prompt — one part (“a funky bassline at 110 in A minor”) or a whole groove (drums + bass + chords + lead), each on its own track.
- •Revise. Keep the conversation going — “make the bassline more syncopated and add a punchy kick” builds on the same idea rather than starting over, and re-imports the result.
- •Improve. “Improve the pluck — give me 2 variations” analyzes the existing part, generates A/B options on new tracks, and mutes the original so you can compare. The original is never deleted.
How to use it
- Type or speak what you want — include tempo, key, and vibe for best results.
- The first generation takes up to a minute (the Co-Producer tells you up front). Each part comes back as its own
.midfile. - Tracks are created and the parts imported automatically — then keep refining in the same conversation.
- “Generate deep-house drums at 124 with a sub bass and a pluck”
- “Create a funky bassline at 110 BPM in A minor”
- “Make the bassline more syncopated and add a punchy kick”
- “Improve the pluck — give me 2 variations”
- “Give me a darker, more driving version of the whole thing”
Audio Analyzer
Ask “analyze this track” or “is my mix too harsh?” and the Audio Analyzer decodes the waveform and extracts real measurements — peak / RMS / crest, spectral balance across the frequency bands, dynamic range, noise floor — then translates them into plain-language issues and suggested processing.
What it detects
- •Problems: clipping, sibilance, harshness, mud, boominess, thinness, an audible noise floor, and over-compressed or over-dynamic material.
- •Suggested fixes: mapped to the problem — sibilance → de-esser, mud → a targeted EQ cut, and so on.
- •Mix-wide checks: “is my mix too loud / muddy / harsh?” renders a full mixdown and reports on the whole balance.
How to use it
- Select a track or region (or just name it), then ask the Co-Producer to analyze it — it reads your live selection, not a stale snapshot.
- Read the metrics, the detected issues, and the suggested processing — then ask it to act (“add a de-esser”, “cut the mud”).
- “Analyze the selected track”
- “What is this track? How would you fix it?”
- “Is my mix too harsh, muddy, or loud?”
- “Go through the session, find clipping and excessive sibilance, and how you’d fix each”
Revocalize Regions
Ask the Co-Producer to “revocalize the Lead Vox track with Lora” and it re-sings your audio regions with a voice model from your Revocalize account, then places the result on a new (Revocalized) Audio track aligned to the original bar positions. Your source track is left untouched, so you can A/B instantly.
How to use it
- Pick what to re-sing. Name a track for all its regions, name one region for just that one, or leave it open to use your current selection.
- Choose a voice. Use a voice name from your account — “what voices can I use?” lists them. Ambiguous names prompt a clarification rather than a guess.
- Tweak settings (optional). Key, scale, harmony, autotune, and transpose default to the plug-in's values and can be overridden in the prompt.
- “Revocalize the regions on the Lead Vox track with the Lora voice”
- “Re-sing my selected regions with Marcus”
- “Revocalize the "Verse 1" region on track 3 with Lora, key A minor”
- “What voices can I use?”
Workflows
Workflows are repeatable Logic Pro automations described in plain English. Build them in Assistant mode, run them from the browser, and switch to Debug mode when one misbehaves.
- You start with $15 free credit per account.
- Running an existing workflow is always free.
- Building a new workflow costs $1–10+ depending on complexity (simple ~$1, multi-step mixing chains up to ~$15).
- Top up at /plans → Co-Producer Credits.
- Credits never expire.
🧩 What is a workflow?
- •A reusable automation. Each workflow is a YAML file that captures a sequence of Logic Pro UI steps — selecting tracks, opening menus, setting values. Run it over and over instead of re-prompting the assistant every time.
- •Two modes. Assistant mode plans, builds, and tests a brand-new workflow from your description. Debug mode points the agent at an existing workflow file so you can test, fix, or improve it.
- •The browser shows only yours. The Browse panel lists only the workflows you've created. Bundled / system workflows are used by the agent under the hood but stay hidden from the UI so they can't be accidentally deleted.
🛠️ Create a workflow
- Switch to Assistant mode. In the Workflows tab, set the mode switcher in the header to Assistant (the purple one).
- Describe what you want. Type a plain-English description of the automation. The more specific the better — include track types, parameter values, ordering.
- Let the agent plan, build, and test. The status ribbon shows progress through
Plan → Build → Debug → Done. The agent saves the workflow as a YAML file when it's confident the steps work. - Find your new workflow in the browser. Click the folder icon in the header to open the Browse panel. New workflows appear under their category. From here you can run them anytime.
- “Build a workflow to mute all audio tracks”
- “Create a mix-prep workflow for mastering”
- “Automate volume fades across all tracks”
- “Build a workflow to split regions at the playhead”
▶️ Run a workflow
- Open the Browse panel. Click the folder icon in the Workflows header. The Workflows section lists your custom workflows by category.
- Tap the workflow you want to run. If the workflow needs arguments (a track name, a tempo, a file path), an inline form appears in the chat. Fill it in and submit.
- Watch progress in the status ribbon. The phase chain at the bottom shows live progress. When it finishes you'll see a result card with elapsed time, step count, tokens used, and a Run Again button.
🐞 Debug a workflow
- Switch to Debug mode. Use the mode switcher in the header. The orb turns amber to signal you're in Debug mode.
- Pick a workflow to test. Open the Browse panel and click a workflow. Its filename appears in the header as a pill — that's the workflow the agent will reason about.
- Ask questions or run live tests. Type things like “Why does this fail at step 3?”, “Test this against live Logic Pro”, or “Improve error handling here”. The agent will trace the workflow and propose fixes.
🚀 Share & earn
When a workflow is reliable in your project, you don't have to keep it to yourself. Push it for review by the Revocalize team — if it's accepted, it lands in the marketplace where other producers can run it and you earn revenue every time it's used.
- Make sure it runs reliably. Run the workflow against a fresh Logic Pro project a couple of times. If it depends on your specific setup (track names, plug-in versions) it won't pass review — workflows should be general.
- Push it for review. Open the Browse panel, hover the workflow, and click the blue Push button (arrow-up icon). The YAML uploads to our review queue. You can keep using the workflow locally while it's being reviewed.
- We review it. Our team checks the workflow for safety, quality and uniqueness. You'll hear back when it ships — usually within a few days.
If accepted, your workflow:
- •🏪 Lands in the marketplace. Other producers can browse and run it from inside Revocalize, with you credited as the author.
- •💰 Earns you revenue. You get paid a share every time another user runs your workflow. The more useful and reusable it is, the more it earns.
- •✨ May join the assistant itself. Standout workflows can be integrated directly into the Revocalize assistant — invoked automatically by the agent whenever a user's request matches what your workflow does. Highest-value placement.
💡 Tips for great workflows
- •Be specific in your prompt. Say “at 120 BPM” rather than “with a tempo”. Name the track type (
Software Instrument,Audio,Drummer) instead of just “a track”. Concrete parameters lead to concrete workflows. - •Keep workflows focused. One operation per workflow tends to be more reusable than one giant workflow that does everything. Smaller pieces compose better.
- •Debug after every build. Right after Assistant mode saves a new workflow, switch to Debug and run it once against your project. Fix any failures while the context is fresh.
- •Sessions ≠ workflows. The Sessions tab in the browser holds your past chat history — useful for resuming a previous build/debug conversation. The Workflows tab holds the saved automations themselves.
⚙️ Requirements
- •Accessibility permission. Workflows automate Logic Pro through the macOS Accessibility API — the same permission the voice agent uses. Grant it in System Settings → Privacy & Security → Accessibility.
- •Logic Pro must be open. Workflows act on the currently focused Logic Pro project. Open the project you want to operate on before running a workflow.
- •Credits. Building or debugging a workflow via the chat agent draws from your credit balance — billed at the actual AI provider cost, accumulated across every internal turn the agent runs (a simple workflow might be ~$1–3, complex ones $10+). Running an already-built workflow is always free, whether it's bundled, your own, or from the marketplace. Every account starts with $15. Top up at /plans → Co-Producer Credits; view your balance in Profile → Credits.

❓ FAQ
Why does building cost more than running?
Building requires the AI to research, plan, write, and test the workflow against your live Logic Pro session — many LLM calls. Running an existing workflow is deterministic; no AI calls at all.
Can I get extra free credits?
Active beta testers and frequent contributors can email [email protected]. We'll work something out.
Can I cancel a workflow build mid-way?
Yes. Hit the cancel button in the Workflow Studio while a build is running. You'll only be charged for the AI calls completed before you cancel.
Voice Input Modes
| Mode | How to trigger | Best for |
|---|---|---|
| Wake Word | Say the wake phrase while Revocalize is listening | Hands-free while your fingers are on your keyboard or instrument |
| Push-to-Talk | Hold Right Option (⌥), speak, release | Quick one-off commands, noisy rooms |
| Manual | Click the mic button in Studio | Deliberate sessions |
| Text | Type into the prompt box | Precise paths, complex parameters, silent environments |
All four modes use the same command language — pick whichever feels right in the moment.
Tips for best voice recognition
- •Speak clearly at a normal pace; don't rush.
- •Reduce background music playback while issuing commands.
- •Be specific: "Create a Software Instrument track called Bass" beats "make a track".
- •Include all parameters in one sentence when you can: "Create a Hip Hop project at 140 BPM in A Minor".
- •Reference tracks by name when possible — more reliable than counting indices.

Troubleshooting
| Problem | Fix |
|---|---|
| Nothing happens when I give a Logic command | Open Settings → Studio, confirm Logic Runner status is Running · green. Re-register if needed. |
| Voice isn't transcribing | Check System Settings → Privacy & Security → Microphone and Speech Recognition — both must allow Revocalize. |
| Push-to-talk doesn't respond | Check Privacy & Security → Accessibility — Revocalize must be enabled. |
| Commands are misheard | Speak clearly, reduce background noise, or switch to text mode for that command. |
| Revocalize refuses to delete something | That's the confirmation gate. Approve once for the session, or tick "Remember" to allow it permanently. |

Each opens a small inline form you can send in a single click. Both go straight to us with the exact command text attached, so we know what you were trying to do.


We read every message — Revocalize is in early beta and your real-world sessions shape the roadmap.
Release Notes
What's new in Revocalize Co-Producer, newest first. Every release during the beta is free to use.
The biggest beta drop yet — Revocalize Co-Producer goes from "moves tracks around" to a true creative partner that generates, listens, and re-sings.
MIDI Generation
Describe a part in plain English and the Co-Producer generates the MIDI, then auto-imports each part onto its own named track. Keep chatting to revise or improve it into A/B variations. Learn more
Audio Analyzer
Decodes the actual audio to flag real issues — clipping, sibilance, mud, boominess — and suggests concrete fixes. Honest by design: no invented metrics for silent or MIDI tracks. Learn more
Revocalize Regions
The Revocalize plug-in's one-click flow, built into the assistant. Re-sing a track with any voice from your account onto a new aligned (Revocalized) track — source untouched for A/B. Learn more
- •MIDI analysis & classification — identify a part (bassline / chords / lead / arp / pad / drums), key, polyphony, and the right instrument from a
.midfile or a software-instrument track.Try: “Classify all the MIDI files in my import folder and tell me what instrument each needs.” - •Region operations — select and mute regions by name to clean up bleed, count-ins, or breaths without deleting anything.Try: “Mute the count-in region on the BG Vocals track.”
- •Plug-in presets — list, load, and save settings on any plug-in (Logic stock, third-party AU, or Revocalize), including nested preset folders.Try: “Open the Channel EQ on track 5 and load a vocal preset.”
- •Smart plug-in discovery & chains — map an intent to plug-ins actually installed on your Mac, plan the chain, route sends to aux returns, and verify the result.Try: “Add a vocal chain to the Lead Vox track.”
- •Multi-window targeting — with several plug-in editors open, commands act on the plug-in you named.Try: “With the Compressor and Stereo Delay open, load a preset on the Stereo Delay.”
