--hallo, Jeremy

the individual outputs are mone and that's what they will stay.
you'd either need a mixer  to make them stereo or do some really
difficult stuff like lowering the volume of tone one ( output1-left)
while increasing tone two (output2-right). but that maybe goes to far
for now.
however you still have two stereo ( mono  and/or poly) outputs ,
namely aux and main. 
i  choose for 6 individual mono outputs plus two poly stereo outputs
for the rest of the voices.  for me that's sufficient
