Download Majik's Music Studio
Free, open-source AI music generation. Apache 2.0 licensed.
Generate, arrange, split a song into stems and mix it — on your Mac or on GPU servers you point it at. You control where it runs.
- Fix — Lego mode on the Create tab actually works. Selecting Lego showed no Source Audio picker and no “what stem” field, so Generate died with `Missing instruction (what stem to generate...)`. Lego now has Source Audio (like Continue) plus a required stem name (bass, sax lead, …). Style is still the sound; it is not a substitute for the stem name.
- Extract, Repaint, and Auto-Complete were the same missing-panel class. Each now has its Source Audio picker. Extract asks which stems to isolate. Repaint asks which time range to regenerate. Auto-Complete takes the partial mix. The app now refuses Generate in-panel instead of sending an empty RPC.

Four lanes, four different waveforms
Every 2-channel file decodes and draws
Faders, sends and a master bus reading LUFS
Threshold, ratio, knee, attack, release — real parameters
Effects chain on the master bus, live while it plays
Your whole library, with artwork, artists and albums
New in 3.6.1
Stem separation that works
Split a song into vocals, drums, bass and other. Each stem lands on its own lane with solo, mute, level and pan — four lanes of real waveforms, not one track wearing four labels.
Waveforms everywhere
Every 2-channel file — which is every normal audio file — used to fail to decode for display, so the Stems lanes, Library rows and the player bar all drew blank. Fixed across the whole app.
Projects that survive
The app keeps a hash-chained journal of every change you make. Reopening a project whose checkpoint is missing now rebuilds it from that journal instead of discarding it. A 121-command project came back intact.
A real mixer and effects
EQ, compressor, limiter, reverb, saturator and chorus — genuine parameters on the audio graph, per track and on the master bus, with LUFS on the master meter.

Features
Multi-Server Generation
Connect multiple ACE-Step servers simultaneously. Round-robin or priority-based routing distributes generation across local and remote GPU backends.
Cover & Style Transfer
Upload a reference track and generate new songs that match its style, tempo, and feel. Cover mode re-imagines existing songs with AI vocals.
Audio Continuation
Extend any track by generating seamless continuations. The AI analyzes the ending and creates natural transitions into new sections.
Genre Variation
Take any generated song and create variations in different genres, tempos, or moods. Explore how your idea sounds as jazz, EDM, or country.
Batch Generation
Queue multiple songs with different prompts and settings. Generate a full album overnight. Background processing with progress notifications.
Import & Analysis
Import existing audio files. AI detects BPM, key, chord progressions, and structure. Use analysis results as starting points for new generations.
Synced Lyrics
AI-generated lyrics with word-level timing sync. Edit lyrics in the built-in editor. Export as LRC for karaoke or subtitle overlays.
Drag & Drop Workflow
Drag songs between library sections, into albums, or out to Finder and other apps. Drag audio files in to import or use as style references.
MCP Server
Full MCP integration for Claude Code. Generate music, manage the library, queue batch jobs, and automate production workflows programmatically.
3 Model Sizes
Small, medium, and large ACE-Step models. Choose based on your hardware — smaller models run on 8 GB systems, large models deliver studio-quality on 32 GB+.
