I have a problem: I have a Phantom X7 Keyboard that I transpose the key to middle C from what ever key the song is played in. When I hook the Midi Keyboard (Oxygen8) to the X7 it does not transpose the key on the midi device when I change it on the X7. It appears to have a midi conflict and works for a moment and then quits. I also have a Yamaha ES6 and it works fine. I have tried it on other X7's with the same problem. I have updated the OS through Roland, etc. I've contacted tech support and nobody there seems to know how to fix it. If anyone has any clue as to how this can be done please let me know by emailing me at montehickey@charter.net. Thanks, Monte
