Hi,
there is an app for Android, FingerPlay MIDI, OSC Midicontrol - http://thesundancekid.net/blog/fingerplay-midi/.
I was thinking about adding support for it for Duplex, which shouldn’t be too difficult - there is already TouchOSC plugin for Duplex. Anyway, on my Renoise 2.6.0 Linux Touch OSC from Duplex is not working, so I have quite limited possibilities to test it.
FingerPlay MIDI includes two XY Devices - I would like to connect them with two first XY Device in Renoise.
Just started reading sources of duplex and touchosc - by maybe some hints?
