how to modify...

hi,

i dont know if im on the right forum,

i have a dtxtreme2s module and a fd8 roland hihats pedals,

i found out that it doesnt compatible with the module, ed morin from drumbalaya.com told me to add resistor between tip and the ring of a balance jack, the value…around 150k, it works only with the switch inputs, make story short

i wonder how to measure the right voltage it receive(dtx) so it(fd8) can work properly,

any thoughts maybe?
