Emocute Studio v8.1 — AI Music Production for Claude

Choosing Your Version (v8 / v8.1)

Emocute Studio is a source package for AI music production. Both v8 and v8.1 are available from this product page — pick the one that fits your setup.

• v8.1 (Claude Code edition) — Runs on Claude Code (Anthropic's official CLI). Unzip, run claude, and you're producing immediately — Claude auto-reads the spec files.
• v8 (Claude.ai edition) — Upload the ZIP to a Claude.ai chat. No Claude Code or terminal setup needed.

If you already bought v8, you'll get v8.1 free of charge. v8 remains downloadable — keep using it if you prefer the chat workflow.

The description below assumes v8.1. v8 users can adapt the same steps to the chat-based workflow.

Emocute Studio v8.1 — AI Music Production Environment

Emocute Studio is an AI music production source package designed for Claude Code. It takes vague directions and helps you design chord progressions, MIDI, lyrics, and Style / Exclude prompts for Suno.

It is not a standalone app. The package bundles Python source code, a harmony dictionary, Suno vocabulary data, production workflows, and spec files that Claude Code auto-reads on startup.

Unzip and run claude. It reads the spec files, picks up the rules, tools, and workflows, and starts producing right away — no upload, no copy-paste setup.

Phrases like "lofi but melancholic," "dark verse, open up at the chorus," or "footwork but keep some sweetness" get translated into chord progressions, MIDI direction, lyrics, and Suno prompts, with Claude drawing on the bundled docs and code.

v8.1 ships approximately 51,000 lines of Python, a 336-entry harmony dictionary, 566 Suno vocabulary words, and 41 Suno production tools (v8 ships at a different scale).

Where Suno Alone Falls Short

Text-only prompts can't reliably push Suno into mid-song modulations or odd meters. Emocute Studio assumes you'll design MIDI and upload it to Suno, so the areas where text prompts fall short become controllable.

• Modulation design — Diatonic, relative / parallel key, half-step up, pivot-chord routes. The design engine proposes modulation paths. Modulate as many times as you want within a single track.
• Odd-meter support — 5/4, 7/4, 7/8, mixed meters. Lock the structure at the MIDI level for meters that Suno can't reliably grasp from text alone.
• Reharmonization — Inject tensions, upper structures, substitute chords, and tritone subs into existing progressions.
• Voice leading — Berklee-style voice-leading optimization. Polish internal voice motion at the MIDI level before handing it off to Suno.

How to Use

1. Tell it roughly what you want "Lofi but melancholic," "a song that opens up at the chorus" — intuitive phrases are enough.

2. Pick from multiple options Genre, concept, BPM, key, song form, and chord-design direction are each presented as multiple options. Once you pick one, it proceeds through chord design, lyrics, MIDI generation, MP3 preview, and Suno prompt output.

3. Refine "Not surprising enough," "push the lyrics harder," "open up only at the chorus," "make it darker" — feedback like this redesigns the relevant section.

What's New in v8.1

The following are added in v8.1 and not present in v8. If you own v8 and need any of these, you can upgrade to v8.1 for free.

• Claude Code support — Just launch Claude Code and the package is ready. ZIP uploads and custom-prompt pasting are no longer required.
• Suno solo renderer — Specify genre / key / BPM and it generates chords, drums, bass, melody, and pads, then outputs an MP3 in one shot.
• Suno prompt as HTML — Style / Exclude / Lyrics / Progression in four blocks, each with its own copy button. Paste each block straight into Suno's input fields.
• Reference track analysis — Drop in an MP3 and it analyzes key, BPM, chord progression, and frequency balance, then proposes a Suno command.
• Suno output analysis and separation — Splits your Suno renders into four stems (vocals, drums, bass, other), runs a quality analysis, and recommends master settings.
• Lyrics quality check — Automatically detects AI-flavored phrasing, overused vocabulary, thought verbs (think / feel / wonder), over-explaining, and structural weakness.
• Lyrics round-trip review — Spawns a separate Claude process (tools disabled, critic role pinned) to review the lyrics, and returns the critique as JSON. It scores the lyrics on six axes — hook strength, AI flavor, signature-tic density, thought-verb count, structural sharpness, and emotional dynamics — and surfaces weak lines along with improvement suggestions. Separating the writer from the critic gives you a third-party perspective free from your own assumptions and preferences. Revise and re-review until the scores stabilize.
• Engine improvements — Performance tags built out for 30 genres, stronger voicing-quality guards, and deterministic RNG control (same input → same output).

Chord Design & MIDI Generation

• Designs chord progressions from vague emotion / genre directions
• 400+ chord definitions (tensions, upper structures, reharmonization)
• 23 genre presets (lofi, neosoul, jpop, house, footwork, jersey, drill, trap, dnb, and more)
• 24 song templates (10 standard / 10 Suno-targeted / 4 experimental)
• 336-entry harmony dictionary / 101 genres
• A single engine that handles chord progressions, full-song structure, and modulation paths
• Odd-meter MIDI generation (5/4, 7/4, 7/8, mixed)
• Berklee-style voice leading
• Bassline / drum / melody generation assistance
• Performance expression via control change (volume curves, modulation, filter sweeps)
• MP3 preview output

Generation Quality Control

• Automatic detection of generic chord-progression patterns
• MIDI analysis (voice leading, range, density, bass, drums, pedal, pitch distribution)
• Aesthetic scoring of progressions (weird / catchy / hard-kawaii direction grading)
• Voicing-quality guard (tension exclusivity, dissonance warnings, root reinforcement)
• Voice-leading checker
• Lyrics quality check (AI-flavored phrasing, thought verbs, overused vocabulary, over-explaining, structural weakness)

Lyrics Generation

• A production workflow that builds lyric drafts from emotional design
• Built-in lyrics quality check
• Notes on phonetics, mora, and hook design
• Reference banks of success / failure patterns and vocabulary to avoid
• Lyric DNA analysis
• Japanese, English, and JP / EN mixed-language support

Suno Production Pipeline

• A 5-phase flow (concept → lyrics → Style design → MIDI → packaging)
• Style design system (category structure, word-count guide, word-order weighting)
• Suno Style vocabulary database: 566 words / 75 genres
• Exclude optimization (contradiction checks, genre-specific templates)
• Vocal persona design support
• Parameter notes (BPM / Weirdness / Style Influence / Audio Influence)
• A MIDI-upload-first workflow
• Failure patterns and improvement logs

We don't guarantee that the same prompt will always yield the same Suno output, since Suno's behavior shifts over time. The current build is centered on operational knowledge from Suno v5 onward.

Additional Engines

• Multi-track arrangement (15 instruments)
• Arpeggiator
• Tempo curve (7 presets, BPM-jump support)
• Trap-specific 808 / hi-hat / snare-roll generation
• Glitch and riser FX pattern generation
• Mathematical MIDI generation (chaos, self-organizing, and noise formulas mapped to notes)
• Chiptune synthesis helper
• HTML player output
• Tap-input tool — mark beats and chord changes by tapping along to a track, then export HTML that Claude can read
• Document consistency check, ZIP integrity check, harmony dictionary search, lyrics linter

Genre Research & Artist DNA

• Genre research notes
• 18-artist DNA breakdown
• Artist influence genealogy
• Reverse lookup by harmony, lyrics, timbre, or rhythm
• Harmony dictionary + Suno vocabulary search tools
• Reference material for "Machinedrum-ish," "Kikuo-style dark kawaii," "Puma Blue late-night," and similar — pull element-level cues from reference names

These resources are for extracting principles of harmony, timbre, structure, and language — not for cloning artists.

Customizable

This product ships with the source code and production docs as-is. It is not a black box.

Ask Claude to "add a preset for this genre," "change the lyrics rules like this," or "register this progression in the dictionary," and grow the package into your own production environment.

The more you use it, the more it becomes yours.

Requirements

• Claude Code (Anthropic's official CLI)
• A Suno Pro or Premier plan is recommended (for the Upload Audio feature)

Claude installs Python, the required libraries (midiutil / numpy / scipy / librosa / soundfile / pyloudnorm / pydub), FluidSynth, Demucs, and other dependencies for you as needed during the conversation. No upfront setup is required.
