Well.. hmm.. where do i start..
First of all check if both scenes are difrent.
So press scene A button + Trigger 1.. then Scene B + trigger 2..
Cause hmm.. if my fader does not work.. its because both sides are the same scene.
Get a beat running... on some track.. and move SOME filter button..
when you found a button that makes drastic sound changes.. u found your perfect
now press SCENE A + KNOB all the way left.. then press SCENE B + KNOB all the way right..
now play with fader... you should hear the same drastic change as you would turning your chosen knob all the way from left .. to the complete other way..
Enjoy playing with your machine...
a good tip though.. sit down with your manual!! and welcome at the forum
