hi
i have just updated my virusA...yipeeee!...after having problems all yesterday and this morn. i got "buffer underun" and "incomplete block" error msgs ....
2 extra things i did.....1 turned tempo of cubase to 50bpm ......and took a midi cable DIRECTLY from soundcard midi out to virus in. (i had the midi from cubase passing through a USB midi controller keyboard with a midi out connection to the virus) IT ONLY WORKED FOR ME WHEN I USED THE DIRECT 5 PIN MIDI CABLE?? ....i have no idea why
mine showed S/E (system exclusive) in the display when i didnt put the virus into UPDATE mode (holding store button while turning virus on.....u did do this yeah???) while playing the sysex msg from cubase. it even showed this S/E in the display when i had it running through the usb route, which made me think it was recieving??!!
hope that may help
