The cables are fine; I reversed them, and also used MIDI B instead of MIDI A. The channel lights on Cubase indicate that MIDI data is coming in and going out. The reason I wrote to this group is because initially I thought it might be an issue with the Korg X5. However, since the lights are off for MIDI out, the problem must be with the interface that I just bought off someone on ebay:-( Thanks for everything Yinka ---------------------------------------------------------------- This message was sent through the Korgy Park mailing list.
