Yes, Iohannes, RjDj scenes work in PdParty. I have tested all of the scenes I have from years ago, including interactive ones which use the accelerometer like the bouncy scene. I do not support scenes generated by the now defunct rjc1000 elper app nor do I support the scene paging feature used in the rjdj intro scene, but AFAIK that's the only scene that used it.
I would hope that other libpd based apps would adopt the same rjdj messaging standard so patches would work, at least, between PdParty & PdDroidParty.
PdParty has been in beta since September 2013 and I've been talking loudly about it since spring of last year. Back then I said it would support RjDj scenes and even posted about my intentions when RjDj was removed from the app store in 2011.
With the beta, I wrote a very detailed user guide that clearly states that it not only support RjDj scenes but also has all of the same rj objects and events ([#touch], [#accelerate], etc). At this point, it is clearly beyond a port of PdDroidParty as I have reimplemented *all* of the Pd-vanilla/iem guis in Obj-C & CoreGraphics. In fact, you can animate and change their color, etc on the fly like in the regular pd gui.
My long term dream would be to add patch creation/editing but that's really contingent on getting some sort of gui helper layer into libpd as I have no desire to reverse engineer parts of the existing gui framework.
I have put out beta calls more than once and have only had perhaps middling interest, with a few people saying they installed it, but far less people have signed up than I would have thought. (A thank you to those that have and bigger thank you to those that have provided feedback.) I recently was told that having to "sign up" for a beta testing service was "far too difficult" and I should just put it on the app store. I imagine those same people would complain on the app store when something that could have been tested in beta didn't work.
The whole point of a beta is to get help finding bugs in a private manner from people who would know what to look for, not the general public or students trying to use it in a class. It's supposed to be a community effort to HELP ME put out a new platform app for FREE. Once on the app store, it should basically *just work* otherwise it will be uninstalled more quickly than the time it took to install it. Also, I was hoping that people would also help me make cool demo scenes & patches, but that hasn't happened either.
All of this is after I've spent probably 2 months of full time unpaid solo work on PdParty in 2013. I could expect that people would in the very least show interest in this project and help me work on it for when I will basically put it out for free on the App Store.
