Restarted. MIDI is back. Operator error, sorry- my fault. I wired it wrong. Fixed. Now- the MIDI loop is back too. I thought, it comming from Raprure, but Rapture track was frozen. Click on snowflake- it got unfrozen. Ouch. Attempted to freeze it again. The system hangs, track saying, "Busy". About 3 to 4 minutes later it gives the visual presentation to the track and playback, but cursor stays in the same place. It means it is readt to drop out. Playing again few more times. Dropout. The system hangs, then relaxes. No crash. Would you like more? If you say, it is all because if XP- I don't think so. The other day it worked, which means- it CAN work fine- minus the loop of unknows origin that no one can figure out. If it played last night, it should play tonight, it does not. 2.35 am. About to give up.
