Set Up HARP in REAPER

To link HARP to REAPER as an external sample editor, do the following:

• Select REAPER > Preferences (Mac) or press control+p (Windows).

• Select External Editors, click Add, then click Browse by Primary Editor.

• Select your HARP executable from your chosen installation directory (e.g., ~/Applications/HARP.app) and confirm.

Open Audio with HARP in REAPER

To load an audio region into HARP without leaving the DAW, we can now do the following:

• (Optional) Right-click a region and select Render items as new take. HARP will perform destructive edits if you save your outputs, meaning it will overwrite input regions. By rendering as a new take, we create a duplicate region and ensure the original is not affected.

• Right-click the (duplicated) region and select Open items in editor > Open items in 'HARP.app'.
