programming drums virus A problemsss

[dilieben]

so i've set the oscillators to phase 1 so they dont keep changing when trigged,for the modes i've choose hold so doesnt matter how much the gate from the sequencer is, but i've a strange sound from the bassdrum like somethimes it plays to loud especially when I plays other parts together.
Any idea of what i'm doing wrong?


p.s no velocity modulation cause that problem

thanks
