Hi Tony, sorry to hear about your MidiSport 2x2 problems. I own the same exact unit and have had no problems installing or running it on my Pentium4 PC running Windows XP. The software driver does require installing in 2 steps (twice), but that is the normal procedure as per M-Audio. Tony, I trust you installed the most current MidiSport 2x2 driver version, right? Just in case you haven't, here's the download link: http://m-audio.com/images/global/drivers/MS2x2_1010_web.exe

The fact that you say that the midi connection (when recording via the keyboard into Sonar) works for 15 seconds then stops makes me suspect that something is (automatically) triggering internally in Sonar or being sent via midi (from your keyboard) to shut off the midi channel. Perhaps try recording on ANOTHER midi channel to see if the problem persists. Perhaps one of our residient midi/Sonar experts here might be able to take a better stab at this and help find the solution. Good luck.

Scott
