When i play my X3 from the my pc the only channel that works is ch.1. i tried everything to get the other channels to work but it did not work. i looked at the clobal settings and there was nothing wrong with the settings. i just want to know if the problem is from the keyboard or from the compter?

If you switch to SEQ mode, you will be able to transmit from every channel if you switch from track to track (having each track each channel);

The effect is the same that if you change in GLOBAL mode the MIDI Channel...

By the way, could your problem be that your sequencer software only accepts incoming data from MIDI Channel #1?
