hi, i have a little problem with my Midi devices and need a help. When I play back my RM1X sequence via midisport 1x1, and I try to play VST instrument such as A1 synth on my Radium keyboard (in Cubase SL situation) there is a terrible latency...even the note stucks and make evil noise so I cannot even listen to the RM1X loops. I'm using OSX and all the m-audio drivers are correctly installed. I don't use USB hub, all two devices are directly connected to my eMac 700.
Since I don't have any other instrument, if I cannot use this combination that means I cannot do anything...if I have to buy another Midi interface to solve the problem, I have enough money though....thank you for listening me.

I redirect you to the OS X forum in case someone has an idea
And changed the title too to help a bit
(sorry I don't have a clue on this problem)
