Ultimate APC40 Traktor Pro Map Project - Rotary Faders + 4 FX units + 4 Deck Support

I've started on a complete mapping for the APC 40 and I wanted to get some feedback on the layout before I invest any more time in it. If you see any problems I might run into please let me know or if you have any advice or feedback I would appreciate it.

I was trying to figure out how I could have full 4 deck EQs, 4 decks, and 4 FX units and I had the idea to make it primarily a rotary fader layout, that way all the EQs, faders, and crossfader are all centered like a normal mixer, and you can have full VU meters on each channel.

I've started working on it but I don't have much experience mapping anything this advanced with LEDs and all of these different modes so it's taking a little while and I want to make sure it's possible before I continue.

For the decks I was planning on putting each deck on a 3/4 grid. Each one has cue points 1-4 up top and then I want to add an option to expand the cue to 1-8 to each deck, where expanding deck a would replace deck B's cue points with deck a 5-8, and expanding deck B would slide all 8 cue points over to the left starting where deck A's were, and you can toggle between either expanded or both with 1-4, and the same goes for deck c and d.

I believe I'll alternate cue LED colors to start with red for grid/cue 1 then 2-4 green for deck A then red 1 yellow 2-4, then when either expand option is selected it will expand to each respective decks color, and the colors duplicated for C/D. If a cue point is not saved for any slot it's status would blink.

On the bottom there are two full effects units and you can toggle between 1 and 3 on the left and 2 and 4 on the right. Then the buttons are on the bottom row with FX select up/down for each. Now that I'm writing this out I would add a FX unit assign on/off as a shift option for each deck.

On the mixer side it is self explanatory, rotary faders, low, mid, and high EQs with kills on the low and highs. Crossfader with options to assign it on/off for each deck (A/C to left and B/D to the right). I want to add a filter mode which replaces the mids with filters for each deck and the high kill buttons to toggle them on/off (or maybe I'll just make that a shift option). List select on the bottom know, shift is tree select, then the bank select buttons load each deck.

I want to add an option to switch the rotary faders to linear faders, then by using the track select buttons you can shift the rotary faders to any of the FX units while keeping the low EQs. Then move the cue buttons to the bottom above each line fader and have those buttons switch to VU meters.

I might possibly put a master VU meter above the master volume fader up the side and if I can switch the buttons to blinking when any of them are selected.

I know this will be time consuming so if you have any advice or see any problems I would appreciate hearing about them now before I run into them which I'm sure I will. Or if you like the idea and are experienced at this you could just make it for me . I'll be sure to share this if/when I can complete it.

Sorry I only have paint on this comp., I also see I'll need to add a browse expand window button as a shift somewhere.
