Split Wizard + for Ableton: Device Overview

Split Wizard is an advanced audio separation tool designed for Ableton Live, leveraging the power of Demucs v4, a state-of-the-art source separation model. It efficiently deconstructs audio stems into up to six distinct elements, offering seven specialized models for precise audio separation. The device utilises Hybrid Transformer Demucs technology for superior separation quality, offering models that cater to various needs, including the separation of drums, bass, vocals, guitar, piano and drum kit elements.


If you want to help I have a website ostinsolo.co.uk you can buy from there and make me independent from Gumroad which is an awful service. Thanks!!

Installation Instructions

Compatibility: Split Wizard is currently compatible only with OSX systems/ macOS 10.13 up and Windows 10/11.

Requirements: Max 8.2 minimum


INSTRUCTIONS: Step by step

1. Click the 'Setup' button within the device and wait [input your admin password]. This will create a folder called spawl in you Max8 folder (Do this only once, it takes up to 2 minutes).

2. Choose the desired model from the provided list.

3. Select an audio clip in Ableton Live session/arrangement and click Start. Once it's done, you can import these stems into Ableton Live by dragging and dropping them, from their relative Icons.

How to use

  • Menu: Sets the model names.
  • GPU: Toggles the use of GPU for processing.
  • Vocal/Multi: Sets the solo vocal mode status.
  • Sets the segment length for processing with GPU.[Segmenting is particularly useful when dealing with memory constraints on GPUs, as it splits the audio into smaller chunks that are processed independently. Example: Setting segments to 10 will divide the audio into segments of 10 seconds each for processing. This can be helpful if the GPU has limited memory but may impact the quality if the segments are too short.
  • Sets the clipping mode to choose between rescale and clamp modes for audio clipping.
  • Sets the number of shifts for processing [A value of 1 means no additional shifts are applied (standard processing). Higher values (like 2, 3, 4, etc.) increase the number of shifts, enhancing quality at the cost of longer processing times.]

Model Descriptions:

  1. htdemucs: The first version of Hybrid Transformer Demucs.
  2. htdemucs_ft: A fine-tuned version of the htdemucs, offering enhanced quality at the cost of increased processing time.
