A friend of mine borrowed me his S4 for some weeks. I set the X1 in the Controller Manager for Deck C+D and used it for full deck controll on these. The volumes, EQs etc. were controlled by the S4, so i just used it as a kind of expansion to controll all decks at the same time and it was pretty fun^^ Try it out!
Didn’t you map some FX to the S4/X1 to make them easy accesible? I’m thinking to do something like this and map these on my X1 and may be some more FX.
It really depends on how you mix. I’m not much into 4 deck mixing. I use decks 3 and 4 more for samples then for playing songs. When I used to use my S4 I believe I had my X1 set up for using the other 2 FX decks that you can’t control, to shoot off samples, and for a bunch of combo fx that I had mapped to different knobs, there were some other random things I had mapped that I can’t remember. Tailor your mapping to your own needs…that’s the beauty of it
Yeah, probably the best use would be controlling decks C and D and FX units 3 and 4. But don’t forget that you still have X1 MIDI mode available where you can map some additional stuff like EQ kills, filters, loop recorder, key adjust, beatjumps or what ever suits best to your workflow.
