I bought a X-Touch mini in order to control some visuals. I am able to receive all the inputs with MIDI-OX:
TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
00001795 1 -- 8A 10 00 11 E 0 Note Off
After releasing the port I tried to receive the same button press with vvvv:
I received nothing. But the port seems to be blocked by vvvv - at least I am not able to connect MIDI-OX while vvvv is still running.
I just tried out the 02_KnowYourDevice.v4p and somehow it didn´t work for me, too. @ayu, did you try to use the MidiShort Node in a different patch? In my case, I can receive data with no problems there, even if I don´t get anything in the tutorial-patch.
By the way, I just googled your device - it seems like it has a special software to configure the midi-output. Did you use that? This might be another place to look for the error. Even if it´s not caused there, you might find something there, like buttons mapped to strange midi-notes etc.
