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.

Verdict
The clearest difference is price: PdParty at Free against miRack's $14.99. PdParty also leads on in-app purchases (none vs 5) and rating (5.0 vs 4.8). miRack's advantage is update cadence (weekly vs every 3 months) and ratings volume (674 vs 16). On ads and device support there is nothing between them.

PdParty is free to download; miRack costs $14.99 up front. miRack sells 5 one-off in-app purchases. PdParty asks for nothing beyond the download.
PdParty holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: miRack has 674 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 78% of PdParty's written reviews are positive against 86% of miRack's, so the app with the better star average is not the one people write more warmly about.
PdParty ships an update every 3 months, miRack weekly. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
