PdParty is an open-source iOS application for running Pure Data patches on Apple mobile devices using libpd. Directly inspired by Chris McCormick's PdDroidParty and the original RjDj by Reality Jockey, PdParty takes a step further by supporting OSC (Open Sound Control), MIDI, & MiFi game controller input as well as implementing the native Pd GUI objects for a WYSIWYG patch to mobile device experience. Various scene types are supported including compatibility modes for PdDroidParty & RjDj and both patches and abstraction libraries can be managed via a built-in web server. Unlike the rise of the single-purpose audio application, PdParty is meant to provide a platform for general purpose digital signal processing via Pure Data patches. Getting Started --------------- New users, check out the User Guide and download the PdParty Composer Pack which contains the abstractions you need when composing on your computer as well as scene type templates. See the PdParty webpage: http://danomatika.com/code/pdparty Who Is This App For? -------------------- PdParty is meant as a platform for running patches created in Pure Data, a graphical programming environment for multimedia. Related to Max MSP, Pure Data allows computer musicians and non-programmers to create custom DSP routines by connecting objects with virtual patch cables. If you don't intend to create your own PdParty scenes or run scenes provided by others, you may not find this app very useful. Please _do not_ download this app and give it a bad rating because you are unsure of what it's for or how to use it. How Can I Support PdParty? -------------------------- In the spirit of the open-source Pure Data community, PdParty is provided for free on the Apple App Store. If you wish to support its author and or PdParty development, consider having your institution sponsor a PdParty workshop, specific development, or a robotcowboy artist residency. Updating -------- See the changelog on the PdParty website for detailed version info. To update the included PdParty patch folders (lib, samples, tests) after installing a new version, use the buttons at the bottom of the Settings page.
