Check that DCO2 is actually turned on - there are eight oscillators, so 
you can have eight-note poly single-oscillator, or four-note poly 
dual-oscillator patches.  If param 18 is set to 1, you can't fiddle with 
the (nonexistent) DCO2.

Get thee to eBay and buy a huge bag of little clicky tact switches, some 
solder braid, a pair of tweezers or forceps, and a really good pair of 
snips.  Remove the top panel PCB and *once you're sure* the 
clickyswitches are the same (you get different heights of button) clip 
off all the old ones with the snips, desolder and remove the legs with 
the tweezers, and clean up the excess solder with the braid.  Now solder 
in all the new clickyswitches making sure you use leaded solder - 
lead-free is useless stuff and will only cause you problems.  Do them 
all at once, because you don't want to be getting that stuff apart twice.

Have fun.
