@ Souf Thanks...
@ The Technician.
1. The mixer on Virtual DJ LE is not mapped because the VMS4 by default mode use it audio interface and routes you PC's audio steam to the Digital mixer.
2.The sampler is routed to deck a and b in virtual DJ LE because of the 4 asio channel interface.The volume knob is simply a parameter change.
3.What effect are you talking about the effects and sample actually use you decks BPM, try it again.
4. because you haven't set a loop. did you?
5.If you are refering to the LED then the answer is "BLue" means that smart loop is active,to deactivate it press shift + Loop/smart. "RED" means there is an active loop in that deck this button will also set a "1 baet loop"
6.The touch strip has 2 layers like a cake. the first layer is not mapped. Press Shift+ slide you finger lightly on the strip up or down to scroll thru you loaded track.
7.That is a skin thing
8. can you paraphrase this, Please.
9. it has a four channel mixer and can interface with 4 virtual decks. We never made any promise.
10. That is your key value in different scales.
