So this is apps that can be connected together for jamming over wifi.
There is a lot of more information on their website plus a lot of information on how to convert Pure Data patches into Android apps plus to make more apps to work in the Pure Data Party Publishers network.
The apps are all for free and no publicity!

In either case there is a new addition to the family called Manoury plus videos covering the different apps.
Google Play info regarding Manoury:
PPP-Manoury is meant to be used with other PPP instruments.
PPP-Manoury is a polyphonic 4 step sequencer ! 4 step is not much, but each step has a probability factor. The synth is a classic additive synth chained to a resonant filter and a 4 tape delay. With the right set of parameters you can go from 80s classics to deep generative textures.
PPP is a framework offering to support midi jamming over wifi features to audio applications and instruments. That means that apps can be connected to each other over wifi with a slave/master paradigm, enabling each sequencer to be in synch with each others. It can of course be used as a standalone sequencer. More here : http://ppp.mgsx.net
