bug fixes

  • fixed wrong VST3 plugin ID. The main issue was that VST3 preset files couldn’t be opened in other VST hosts and vice versa.

NOTE: You can still open old “wrong” preset files, but this might go away in future versions, so you’re advised to open and save your old VST3 presets to “convert” them to the new correct format. But first you need to clear the plugin cache with [search_clear 1( and do a new search to update the plugin IDs. Sorry for the inconvenience!

  • fixed possible crash when opening plugins asynchronously

  • fixed possible crash when quitting Pd (especially on macOS)

  • fixed crash with certain VST3 plugins when saving presets

  • disable window resizing if the GUI editor has a fixed size


  • resizable VST3 GUI editors are now supported
