I made a vvvv module for FingerplayMIDI, the Android MIDI controller app. You can download it here.
There is now an advanced version available, by the vvvv vvvveteran kalle. This version has better structure, and supports multiple instances (so you can theoretically have several Fingerplay clients connected to your server, each controlling different things). I've yet to try if FingerplayServer supports this, but I will update this post when I have!
