# Model Card for musicgen-songstarter-v0.2

[![Replicate demo and cloud API](https://replicate.com/nateraw/musicgen-songstarter-v0.2/badge)](https://replicate.com/nateraw/musicgen-songstarter-v0.2) [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/gist/nateraw/0cb4c242b70af10044e9ae73f4617c86/songstarter-v0-2-demo.ipynb) [![Open in Spaces](https://huggingface.co/datasets/huggingface/badges/resolve/main/open-in-hf-spaces-sm.svg)](https://huggingface.co/spaces/nateraw/singing-songstarter)

musicgen-songstarter-v0.2 is a [`musicgen-stereo-melody-large`](https://huggingface.co/facebook/musicgen-stereo-melody-large) fine-tuned on a dataset of melody loops from my Splice sample library. It's intended to be used to generate song ideas that are useful for music producers. It generates stereo audio in 32khz.

Compared to [`musicgen-songstarter-v0.1`](https://huggingface.co/nateraw/musicgen-songstarter-v0.1), this new version:
- was trained on 3x more unique, manually-curated samples that I painstakingly purchased on Splice
- Is twice the size, bumped up from size `medium` ➡️ `large` transformer LM

## Usage

Install [audiocraft](https://github.com/facebookresearch/audiocraft):

```
pip install -U git+https://github.com/facebookresearch/audiocraft#egg=audiocraft
```

Then, you should be able to load this model just like any other musicgen checkpoint here on the Hub:

```python
import torchaudio
from audiocraft.models import MusicGen
from audiocraft.data.audio import audio_write

model = MusicGen.get_pretrained('nateraw/musicgen-songstarter-v0.2')
model.set_generation_params(duration=8)  # generate 8 seconds.
wav = model.generate_unconditional(4)    # generates 4 unconditional audio samples
descriptions = ['acoustic, guitar, melody, trap, d minor, 90 bpm'] * 3
wav = model.generate(descriptions)  # generates 3 samples.

melody, sr = torchaudio.load('./assets/bach.mp3')
# generates using the melody from the given audio and the provided descriptions.
wav = model.generate_with_chroma(descriptions, melody[None].expand(3, -1, -1), sr)

for idx, one_wav in enumerate(wav):
    # Will save under {idx}.wav, with loudness normalization at -14 db LUFS.
    audio_write(f'{idx}', one_wav.cpu(), model.sample_rate, strategy="loudness", loudness_compressor=True)
```

## Prompt Format

Follow the following prompt format:

```
{tag_1}, {tag_1}, ..., {tag_n}, {key}, {bpm} bpm
```

For example:

```
hip hop, soul, piano, chords, jazz, neo jazz, G# minor, 140 bpm
```
