Increasing Sequence Click Track Volume?

I am having trouble with an individual instrument out volume control for the click track out to my drummer. I have the instrument volume cranked to 127 and used a Standard Drum sound (the loudest I have) to create the click track. I assigned the click track instrument out to channel 4 and put in a 1/4 inch cord into the rear of the X6 to run to my drummers ear piece, but he states it isn't loud enough. I told him to quit hitting his drums so hard, but as us keyboard players know that isn't going to happen anytime soon (he is a hard hitting drummer but he laughed with me when I told him this possible solution). I told him I cranked the volume as loud as it will go and centered the fader.

Now for my question, if you can't already guess where this is going, is there another way to internally amplify the sampled sound to increase the volume of the individual instrument, and if so how do I save the instrument that way permanently so I can continue to use this instrument as my permanent click track so my drummer can hear the click? Or is there another way to increase the volume internally that I am not thinking of right at this point. I am still trying to get used to this board, it's outstanding and so much easier to use than my old school, in the attic, Emu Emulator II. Thanks to all those that help us old school (prior to midi) musicians with these new fangled git gadgets.
