Reply to help VCI100 mapping for: loop move & beat jump

Hey gang. Im trying to believe of a good way to include the following functionality into my VCI100 arcade.

I want to keep as much of the djranking s VCi100se_2_4 as possible...

Move a loop 2back
Move a loop 2fwd

Beatjump 2back
Beatjump 2fwd

Anythoughts of how to map this and what buttons?

For Beat jump:
I was believeing perhaps holding the "sync" button, combined with pressing "drop cue" (2back) or pressing "play cue" (2fwd) might be cool - is this technically feasible?

For Loop jump:
The same above would work when the deck has the loop enabled.

Would it work with four decks?

I am new to building custom mappings so any suggestions on how to do this would be excellent!

peace and keep rockin those decks!
