Basic HARP Workflow

HARP supports a simple workflow: pick an existing model for processing or provide a URL to your own, load the model and it's corresponding interface, tweak controls to your liking, and process.

To get started:

• Open HARP as a standalone application or within your DAW
• Select an existing model using the drop-down menu at the top of the screen, or select custom path... and provide a URL to any HARP-compatible Gradio endpoint
• Load the selected model (and its corresponding interface) using the Load button.
• Import audio or MIDI data to process with the model either via the Open File button or by dragging and dropping a file into HARP
• Adjust controls to taste in the interface
• Click Process to run the model; outputs will automatically be rendered in HARP
• To save your outputs, click the Save button or select Save As from the File menu

In the example below, we use the Demucs source-separation model to extract the vocals from a music recording.

Note that HARP is a destructive editor -- if you use it to edit regions in your DAW, saving will automatically overwrite input regions. You may therefore wish to create a duplicate or "bounced" region to pass to HARP as input.
