I'm not infront of my board, but if I remember correctly, in the Sequencer, go to Setup. You should be able to set the transmit channel per track. Holding down Shift+one of the 16 track keys is also a shortcut for transmitting on that midi channel. Useful in multi mode. What you want to do should work. if you want to Sync the sw1000, then make sure Midi Control is ON (under Sequencer Setup). If you don't want to send it midi clock info, turn Midi Control Off.
