Hello!! 

I dont know about 64 bit. I am running win 7 32 bit. 
But If you could get midiox and midiyoke for win 64 bit then it should work. But its worth a try.

There was a guy that made a pro channel version of Ah's plugin (if you know it) for the bcr2000. The plugin would follow mackie mode so if you selected a channel the bcr would jump to that channel and you could control the pro channel. That doesnt work on x2 though.. That would have been great. Cos Act doesnt follow the pro channel. for e.g if you have an efefct in channel 1 and an effect in channel 2, you could have a preset on  ur bcr2000 for ACt. You select that track, and act focuses directly on the 1st plugin in the selected track. you press the assigned button to open the plugin and you can control it. then press close and close it. but it wont focus on the prochannel you have to click on the prochannel for it to focus.. But with that pluygin you could just select the track and control prochannel in a different preset on your bcr2000. 
I also noticed that when I updated to X2a, Act wouldnt focus on the effect bin now but it would focus on the prochannel. The opossite to x2 plain. But you could get used to that I guess.. i uninstalled x2a and now im  in x2 cos of that. i like it.

I will make some files, who ever wants the mappings and any help, pm me!  :)

For most commands you dont need midiyoke.. I used midi yoke to fix a problem with the mute and solo buttons.. without midi yoke u need to press them twice..

find a pic of the vs700 online and zoom into it and see the commands.. they are all midi notes and I have found most of them!! ITS LIKE HAVING YOUR OWN  V S 700 but with bcr2000 and a bcf2000.. I have 2 bcf2000s and a bcr2000 and I got a great controller!!

You can try it right now.. withought the midiyoke and midiox you can still do it.. But the solo and mute buttons will need to be pressed twice  for solo off on.
remove the mackie mode control surface, put your bcf2000 in b1 or anything, and do this..

faders 1 - 8 set to
Pb, ch 1 -8.

for solo set one row of buttons 1 - 8 to

notes 8 - 16 and value1 127

for mute its notes 16 - 22

try it.. with midi yoke i did some mapping and the solo mute buttons work normally. i also made fader touch select channel. and some other stuff.

oh!!
try this also.. 


set a knob, (i use the upper right knob) on the bcr2000 to CC, channel 1, 60, 0 -127, rel 3
and you have a Jog wheel to go through your project!!
:)
all this is done buy using the v s700 control surface plugin. NOT the mackie control!!

you dont need midiyoke for these. these are commands that the vs700 uses.


you can create your own custom mode. you dont use the makie mode on the bcf2000 either..

you can set your knobs to be PAN by setting them to CC ch1 from 16 to 23 for track 1 to 8. 0 - 127,  rel 3

note 70 channel 1, 127 is the SHIFT key. so set a button to do that and you have your shift. us shift and a solo button and you get the input echo on/off.
there are many more commands.
