pitch envelope modulation through matrix

[nutrinoland]

hi...

when i set it so the pitch of an oscillator is modulated by the filter envelope,through one of the slots in the matrix section, does the filter envelope continue to simultaneously function as a filter envelope too ??
how do i de-link these two functions ?
can i have the pitch modulated differently than the cutoff... ?

are there only 2 envelope (generators)...?


thanks
