this is a quick and easy demonstration of one of the aspects that sets z3ta apart from other simpler synthesizers - routing the signal to two seperate filters
first off create an empty preset then turn OSC 1 to a saw wave, and OSC 2 to a square.
then send OSC 1 to filter 1 by moving the BUS slider all the way to the top. do the opposite for OSC 2
Then make each filter a different type - I made number 1 a low pass 
and number 2 a high pass
-
to make it a little easier to differentiate when youre hearing each wave pass through each filter...
now go to the LFO section and turn 1 and 2 on - set them both to a sinewave and to sync - 4
finally go to the mod matrix and set each filters cutoff value to be modulated by a different LFO

now hold a note and you should hear the two waves crossing over each other - each with different filter characteristics
