Iv’e been having problems with stuck notes in VSTi (EWQL and VSL Vienna Instruments Pro). This happens when playing live or monitoring a recording, but everything on the recording itself is fine, so Cubase seems to be getting the right MIDI data.
I’m using a Kawai MP10 digital piano and Korg Nanakontrol2, both over USB.
I’m on PC with Windows 8.1.
BTW I’ve tried disabling ASIO Guard, and the various timestamp options and nothing makes any difference.
