kicks and snares acting strange

hullo, i used the standard programms(dj-hip set, ill_hip_set, nuskool set, etc) and pads and everything was fine, but today, all the programms kicks (pad 2) and snares(pad 6) of are acting strange; they are much too quiet, while the rest of the pads sound normal. sometimes the snares increase in volume, then quiet again...Help please

(my set up is: mixer behringer eurorack ub502, reason 3.0, mpc1000, edirol keyboard, edirol UM-1ex usb interface.)

Try going to 'other' mode and checking the pad sensitivity for pads 2 and 6 (compare them with your other pads). Might be that you've made 2 and 6 much less sensitive than the others, hence the level drop.

done that, but the level sensitivity is the same for all the pads. fokkit, think it's just my mixer....
