Perhaps if someone else who has a xp64 system with 8 GB ram could also test this.
Try loading more than 3 GB of samples into 13 midi channels in VE. Then save the file as a project and re-open it. See if Midi is being received. It should be. Then load one more matrix into channel 14 to make 14 midi channels and save this as a new project file. Re-load this file and see if the midi is being received.
Thanks if anyone has time to do this. That way I would know whether or not to start looking at my Wavecenter PCI card's midi as a culprit. (but since rgames is using different midi in devices and getting somewhat similar problems, I don't think right now that it's the midi/audio card).
