A local music-generation workspace for Mac
SongForge (bundle ID: com.hrs.songforge.app) is a native macOS application built by HighRoad Software (COBI Management SRL, Belgium). It generates vocals and instruments together with a compatible ACE-Step 1.5 model running locally on the Mac. You provide a prompt and can set lyrics, style, BPM, key, and vocal language. Models are downloaded or linked during setup, and the normal standalone generation path then works locally. Network exceptions include model downloads, purchase or direct-build licence validation, support links, and an Audio Unit remote backend only when the user explicitly configures and confirms one. The current release build does not offer model training as a supported feature. SongForge requires macOS 14 or later and is currently in release validation.
From a prompt to a library you control.
Write the brief, keep the results organised, then make a variation without leaving the app.
Everything you need to make music with AI
From a single sentence to a full produced track — SongForge handles the whole creative process on your Mac.
From idea to full song in minutes
Type what you hear in your head. SongForge's generation panel gives you full control: add a text prompt, paste your lyrics, pick a style preset, set the BPM and key, choose a vocal language, and hit Generate. Use Simple mode for one-click results or Custom mode to fine-tune every parameter.
- Simple and Custom generation modes
- Lyrics, style, BPM, key and vocal language controls
- Variation groups — generate siblings from the same prompt
- Re-roll individual songs without losing the rest
- Parallel tasks — queue multiple generations at once
- Keyboard shortcut ⌘G to generate from anywhere
Your Mac is the studio
SongForge runs the ACE-Step 1.5 model entirely on your hardware using GGUF quantization and Apple Metal GPU inference. On first launch, download the 4-file model set (~6 GB) from Hugging Face — after that, every generation is completely offline.
- ACE-Step 1.5 — state-of-the-art open music model
- GGUF quantized for efficient on-device inference
- Metal GPU acceleration on Apple Silicon
- No internet required after first model download
- No prompts or audio logged anywhere
- GDPR by design — you are the sole data controller
Everything you make, beautifully organised
Every song you generate lands in your Library. Browse, search, and organise your creations with a full-featured player bar: scrubbing, shuffle, repeat, playback rate control, and keyboard shortcuts. Liked songs, variation groups, and smart search keep your library tidy as it grows.
- Full player bar with scrubbing and playback rate
- Shuffle and repeat modes
- Liked songs & variation group organisation
- Full-text search across all songs
- Library backup and restore
- Keyboard shortcuts: ⌘P play/pause, ⌘L library
Take a track further
The release build includes work toward MP3 and WAV export, stem separation, and VAE remix tools. Final paid-edition scope and pricing will be published only when checkout is live; model training is not part of the current release.
- Local creation and project library
- MP3 & lossless WAV export
- Stem separation: vocals, drums, bass, melody
- VAE remix tools — re-compose existing songs
- Final paid-edition scope confirmed at launch
Three steps from prompt to playback
Choose your model
On first launch, SongForge downloads the ACE-Step 1.5 GGUF model set (4 files, ~6 GB) from Hugging Face. This is a one-time download — the app guides you through it automatically and all future generations run fully offline.
Describe your song
Enter a text prompt describing the song you want. Optionally add lyrics, choose a style preset, set BPM and key, and select the vocal language. Use Simple mode for instant results or Custom mode for precise control over every parameter.
Let the AI create
Press Generate (⌘G). ACE-Step 1.5 runs on your Metal GPU and produces a complete song — vocals and instruments — in minutes. Listen immediately in the built-in player, generate variations, or export to MP3/WAV with Pro.
Local by default, explicit when connected
Standalone generation and the project library run locally, with no SongForge account or analytics. Model delivery, purchase validation, support links, and an Audio Unit remote backend you explicitly configure are the documented network exceptions.
