KC changes Cubase SX pans/volume
 

Sometimes when pressing some key, in cubase some channel's volume drops to zero or pan jumps to left or right. What the heck?! There's no sense at all. Key could be just some key and channel in cubase could be just any channel (not allways MIDI-channel, could be audio-channel too!). Sometimes volume changes or pan. Why is that? Why virus changes those settings? Without virus volume or pan doesn't change.

Check your incoming midi filters within SX.

:D

There are marked only Sysex. What should I change there?
