So the tascam us2400 is in fact only 1/3 compatible?

I bought the tascam us2400 because it has 24 faders..and clearly mentioned in the RME manual as being a compatible (mackie protocol) midicontroller.. When i read this i expect it to use all 24 of it's faders simultaneously for controlling totalmix, and not only 8!

Is there a way i can assign all 24 faders on the tascam us2400 to control 24 faders of choice (in the top/middle or bottom row) SIMULTANEOUSLY in Totalmix? And of course i want to use all 24 mute/solo/pan buttons on the tascam us2400 as well to control the mute/pan/solo buttons in Totalmix..

And i would also find it logical that totalmix sends it's information back to the tascam so if i select another output in the bottom row, all faders/mute/solo/pan settings of the top input row (and the middle row) update on the tascam us 2400..

I don't expect an full explanation of how exactly to do this..That i can find out myself..
I only need to know if this is in fact possible:
FULL PROGRAMMABLE MIDI CONTROL between RME HDSPe Raydat Totalmix and Tascam US2400 for all faders/buttons..

Thank you for the fast response,

If i understand correctly this is now possible in the new totalmix fx?
I need to make sure it is to make the upgrade and sell my Raydat..

So to make sure:

1. i read this on the rme totalmix fx forum:

"Totalmix FX: 4 new features in the Settings dialog (F3)
... Tab MIDI: now supports up to 4 MIDI remote ports simultaneously..."

2. From the manual US2400:

"Each bank of 8 faders on the US-2400 appears to the computer as one MIDI port, with the leftmost fader
bank containing channels 1 through 8 ..."

"For DAWs that support multiple control surfaces as a single unified device, assign each US-2400 MIDI port to a separate control surface entry. Generally, you’ll have to choose a control surface here that allows the DAW to find the US-2400 in a particular control surface mode. For example, if the US-2400 is emulating the HUI protocol, you would choose
three HUI devices, each one on a different US- 2400 MIDI port..."

"Assign the ports left to right as follows: Port 1 represents faders 1–8; Port 2 represents faders 9–16;
Port 3 represents faders 17–24; Port 4 represents the joystick. Note that Port 1 includes the master section controls. Enable the US-2400 MIDI ports in your DAW’s MIDI configuration window, open the Control Surface configuration window in your DAW software..."

So all this means i can control the new totalmix fx with the US2400 using all 24 faders simultaneously without having to bank up or down?

And also:  is there an easy way to select submixes while staying in the upper row in totalmix?
for example:
- i select submix 1/2 (with an assigned button on the us2400)..24 faders update on the us2400 showing me the upper row of TM..adjust all 24 faders without banking
-then i select submix 7-8 (with an assigned button on the us2400)..24 faders update on the us2400 showing me the upper row of TM..adjust all 24 faders without banking   
-and so on

I apologize if this is explained already, but i tried to find it and didn't find a clear answer on this..
Or maybe i am not enough of a midi expert to understand correctly..
I hope someone can help me!
Thanks
