Purr Data 2.5.1 is now available:


Please report bugs here:



  • speed up message box by removing the malloc/free per incoming message
  • added regression test framework with some initial message box tests
  • add linked errors in the console for message parsing errors. This allows you to "Find last error" for messages that don't have enough args, have a bad selector, etc. You can also click the link for the relevant error in the console to find them
  • add "x" and "y" methods for [draw image]
  • fix a regression with [pd~] (Thanks Albert!)
  • add Vanilla version compatibility to "About Pd"
  • build fix for make light (Thanks Giulio!)
  • add more midi device slots to the Preferences dialog
