RRADical Pd is a project to create a collection of Pd patches, that make Pd easier and faster to use for people who are more comfortable with commercial software like Reason(tm) or Reaktor(tm). RRAD as an acronym stands for "Reusable and Rapid Audio Development" or "Reusable and Rapid Application Development", if it includes non-audio patches, with Pd. In the design of this system, a way to save state flexibly in Pd (persistence) had to be developed. For communication among each other the RRADical patches integrate the Open Sound Control protocol.
