Hello,

That's odd that you have no ignoreportfilter file on your system. If you reinstall SX3, you should find that file in the MIDI Port Enabler folder. It's possible that you may need that file there in order for MIDI to record properly. Some MIDI interfaces need that file and some do not.

It's possible that the MIDI interface and/or it's drivers are not transmiting the information accurately, but I'd first see if you could get SX3 installed and try recording MIDI with the ignoreportfilter folder inside the MIDI Port Enabler folder and if that doesn't work, cut and paste the ignoreportfilter file to the Cubase SX 3 folder and try recording MIDI using the emulated port.
