We present 4 model variations:
|
255 |
-
1. Melody -- a music generation model capable of generating music condition
|
256 |
-
on text and melody inputs. **Note**, you can also use text only.
|
257 |
-
2. Small -- a 300M transformer decoder conditioned on text only.
|
258 |
-
3. Medium -- a 1.5B transformer decoder conditioned on text only.
|
259 |
-
4. Large -- a 3.3B transformer decoder conditioned on text only (might OOM for the longest sequences.)
|
260 |
-
|
261 |
-
When using `melody`, ou can optionaly provide a reference audio from
|
262 |
-
which a broad melody will be extracted. The model will then try to follow both
|
263 |
-
the description and melody provided.
|
264 |
-
|
265 |
-
You can also use your own GPU or a Google Colab by following the instructions on our repo.
