Ok so I will answer myself...
Allthough the MIDI protocol is serial, and the same goes for USB, no more than one MIDI values should arrive at the exact same time to the Arduino from the MIDI controller.... but this is exactly whats hapening with the QuNeo. QuNeo sends more than one value in the same USB Packet... the current code allows just for one MIDI message per USB packet.
The developer of the library is working on it... so thankfully this issue will be solved soon... Will post results once is working!!
Cheers!
