The Workflow was setup to have a clean "GUI" showing only parameters that matter, so you might want to toggle off Link visibility, like in above screenshot.

V1.7 Ace Step 1.5. Turbo and SFT normal and XL model with Ollama. Text to Audio/Song (examples below).

  • replaced the "save Mp3" nodes to allow ID3 tags to include data like artist name, bpm, genre, lyrics, etc.

  • added a feature to save all relevant data (tags, lyrics, etc.) as a separate text (.txt) file

  • audio render processing remains unchanged to previous version

Key features:

  • Can use any Song, Artist as reference or any other description to generate tags and lyrics.

  • Will output up to 4 songs, each by Turbo, SFT, Turbo XL and SFT XL model.

  • Keyscales, bpm and song duration can be randomized.

  • able to use dynamic prompts.

  • creates suitable songtitle and filenames with Ollama.

  • Lora Loader included,

V1.6 Ace Step 1.5. Turbo and SFT normal and XL model with Ollama.

updated the settings for XL models and added a 3rd System Prompt for tags to chose, with more descriptive song descriptions.

1.5 XL SFT pipeline now has an "Adaptive Projected Guidance" node and negative prompt.

** See below some tips which model and settings to start with.

V1.5 Ace Step 1.5. Turbo and SFT normal and XL model with Ollama:

  • setup to create up to 4 tracks in a run, 2x Ace1.5 and 2x Ace1.5 XL, each with Turbo and SFT model, to compare (can be individually switched on/off)

  • VAE changed to tiled Audio VAE decode, uses less Vram.

V1.2 Ace Step 1.5. Turbo and SFT model with Ollama Text to Audio/Song

  • small update to GUI, system prompts and SFT sampler "engine"

V1.0 Ace Step 1.5. Turbo and SFT model with Ollama Text to Audio/Song

Ace Step uses TAGS and LYRICS to create a song. These can be generated by Ollama or by own prompts.

Avoid sage attention in your comfyui starting parameters, avoid --lowvram setting, as this might force Texencoder to run very slow on CPU instead of GPU.

Ollama Models, required for tags, lyrics and songtitle, you can choose 1,2 or 3 different models, tags and lyrics might need a bigger model >7b, songtitle can use a smaller model:

Alternative Turbo and SFT Models (normal, non XL) :

GGUF Models "normal" and XL: https://huggingface.co/Serveurperso/ACE-Step-1.5-GGUF/tree/main

Which models to start with ?

  • My current choice for normal model: Turbo-SFT merge_ta_0.5 & SFT-Shift1, using these settings:

    • Turbo-SFT_merge model with sampler: er_sde, scheduler: beta57 (or beta), 22 steps

    • SFT-Shift1 model with sampler euler, scheduler: normal, 138 steps

  • XL Model settings:

    • XL Turbo-SFT merge model: sampler: er_sde, scheduler: sgm_uniform, 40 steps

      • alternative: sampler: res_s2, scheduler beta57 (requires RES4LYF custom nodes)

    • XL SFT model: sampler: euler (or res_2s), scheduler: normal, 46 steps, CFG = 7.3, Adaptive Projected Guidance: eta = 1.05, norm_thresh= 1.3, momentum=0.0. Increase norm_thresh as the main parameter. These settings deliver "stabil" output for XL SFT,Base and their merges. The merges sound way better, pure SFT or Base introduce a lot of noise. I bypassed ModelSamplingAuraflow (see node next to model loader node). I think the base-turbo XL model merge fits well in that slot.

  • Disable "generate_audio_codes" in "TextEncodeAceStep" node to get different results, it works very well for many genres and reduces process time.

  • Ollama Model: Llama-3-NeuralDaredevil-8b-abliterated
