It may sound better using stereo outs. There is a design error that if you’re doing mono out of the ‘L/MONO’ jack the instruments that are panned right may not sum/mix to that jack properly.
Best way to know is to give it a try in stereo.
The error is described here…

I ended up building a simple passive resistor ‘mixer’ to sum left and right out of each output. Some drumsets do sound different using this versus just output from the L/MONO jack.
Using 1/4" TS plugs for this…
