1. Create a new empty Cubase SX project and then create an empty 1 bar part on the first track.
Set the output of the track to a GM device. Don’t make any other settings in this inspector panel.

2. Select the empty part again and Press control G to open up the list editor. In the top toolbar, set quantise to 1/8 or 1/16 and turn snap on.

3. Set the ‘insert’ drop down menu to Sysex, right click for a pencil tool, and in the timeline on the right insert an event on the first beat. A line of information will appear; on the far right you will see the Hex numbers F7, F0. Drag the window pane to reveal more of this column.

4. Click on the F7, F0 characters in the column; the 'Sysex Editor pane' should open, with the same characters displayed.

5. In this window click four times on the Insert button - this should insert four lots of '00' characters between the F7 and the F0.

6. Click on each '00' in turn and change them so that the whole message string reads: F0,7E,7F,09,01,F7.
You've just written a 'system exclusive' midi message string in hexadecimal. The message is a universal 'GM reset' instruction.

7. Close the Sysex editor and the list editor.
In the arrange page press num key 1 to set the cursor back to the start of the part.

8. Now watch the front panel of your synth module (you remembered to set the track output, didn't you?!?) and press play: you should see the synth change to 'GM' mode as the sysex message plays through.
Complete load of tosh! I forgot this the GM reset command and not a midi device reset.
