Is quite stuttery almost like any particular note can jump just in or out of time quite random infact??
I had this problem for a while but after fiddling round with different buffers sizes and making sure i selected the right soundcard in .. SX<DEVICES<DEVICE SET UP<VST SYSTEM LINK and also VST MULTI TRACK .. This seemed to have sorted it for me!!!
Try it, make sure you have the right midi ports selected in SX<DEVICES<DEVICE SETUP<MIDI PORTS! also
urmmpp also check your preferences in SX and make sure you dont have anything filtered that you might need changing ... check... SX<PREFRENCES<MIDI<CHASE EVENTS FILTER. check also you dont have SYSEX filtered!! though to be honest might not change alot but worth going through all of um!!
You probably might of already checked all these, if so I havnt got a clue!!
Good luck though!!
