| # Foundation-1 — Mirror |
|
|
| **BPM/Key-Aware Music Sample Generator** |
|
|
| [Original Model](https://huggingface.co/RoyalCities/Foundation-1) by [RoyalCities](https://huggingface.co/RoyalCities) · Fine-tuned on [stable-audio-open-1.0](https://huggingface.co/stabilityai/stable-audio-open-1.0) |
|
|
| > This is an **ungated mirror** of the Foundation-1 model weights for use with [ComfyUI-FFMPEGA](https://github.com/AEmotionStudio/ComfyUI-FFMPEGA). All credits go to the original authors. |

|
| ## What's in This Repo |
|
|
| | File | Description | Size | |
| |------|-------------|------| |
| | `Foundation_1.safetensors` | FP16 model checkpoint | ~3 GB | |
| | `model_config.json` | Model architecture config | ~1 KB | |
|
|
| ## What Foundation-1 Does |
|
|
| Foundation-1 generates production-ready musical loops with fine-grained control over: |
|
|
| - **Musical structure**: BPM, bars, time signatures, key/mode |
| - **Instrument identity**: 30+ instrument families (synth, strings, brass, guitar, etc.) |
| - **Timbral control**: 100+ timbre tags (warm, bright, gritty, glassy, etc.) |
| - **FX prompting**: Reverb, delay, chorus, distortion, and more |
| - **Loop fidelity**: Seamless, tempo-synced loops designed for layering |
|
|
| ## Usage with ComfyUI-FFMPEGA |
|
|
| These weights are auto-downloaded by the **FFMPEGA Agent** node: |
|
|
| 1. Set `llm_model` to `none` |
| 2. Set `no_llm_mode` to `generate_sample` |
| 3. Enter a prompt like: *"Synth, Pad, Warm, Wide, Lush, 120 BPM, 4 Bars, C major"* |
|
|
| The model (~3 GB) downloads on first use to `ComfyUI/models/foundation1/`. |
|
|
| ## Hardware Requirements |
|
|
| - **VRAM**: ~7 GB during generation |
| - **Generation speed**: ~7–8 seconds per sample (RTX 3090) |
|
|
| ## Prompt Structure |
|
|
| Foundation-1 uses a layered prompt system: |
|
|
| ``` |
| [Instrument Family], [Sub-Family], [Timbre Tags], [FX Tags], [BPM], [Bars], [Key] |
| ``` |
|
|
| Example: `"Synth, Lead, Bright, Sharp, Saw, Detune, Delay Ping Pong, 140 BPM, 8 Bars, A minor"` |
