Well, i ran into this problem with drumazon also.
Normally when i want to mix the instruments seperatly(of a vst), the main out of that instrument will be disabled.
Drumanzon and also nepheton don't dissable the main outs when chosing a instrument to mix seperatly, so i have to mute the whole main channel, otherwise i get a double signal.
For instance i choose the snare on out 3, the snare also keeps giving signal volume on main 1 and 2.
Could this be adjusted? or is it allready possible, and am i overlooking something?
Ill hope u understand my poor explanation in english.
