Problem using Novation control surface with PT M-Powered

[juanfranela]

Hello,

Here's the hardware and software:
Windows Vista
Pro Tools 8.0.1
M-Audio Fast Track Pro soundbox
Novation 25 SL control surface

I'm connecting via MIDI cables.

Here's the problem:
My Novation 25 SL recognizes the plug-in I've loaded in PT. I can use the surface to control some settings, but the control surface keyboard won't allow me to play the instrument. For example, I bring up the DB-33 in PT. I can control the sliders using the Novation control surface, but the keyboard won't play notes (though I can play notes by clicking on the keys displayed on the screen).

I'm sure I'm missing something fairly basic here. So far:
- Set up AutoMap 3.4
- Went to Setup > MIDI > Input Devices..., and
selected Automap HUI, Automap MIDI, Fast
Track Pro MIDI In, and ReMOTE SL
- Went to Setup > Peripherals > MIDI Controllers tab, and
selected Type=HUI and set receive and send dropdowns
to Automap HUI.

One thing, each time I set up the peripherals as above (which is what the documentation I've found so far says to do), I get the following message: "Pro Tools is unable to communicate with HUI. Please power cycle HUI and check its connections."

Any ideas? This is killing me.
