LFO Sync to Protools; please help?

[typhy]

I'm trying to sync the SP's LFO to my PT session's tempo.
I don't know what I'm doing wrong.. can someone help me?
Here's how I currently got it set up:

SP > interface via USB
SP Midi set up menu: in - USB / out - USB
LFO Sync - clock SRC: MIDI

LFO rate is all the way up (1/32T) and set to SAW for source.
Amount all the way up, destination set to filter.
Mod wheel on Axiom is all the way up.
(PT session is at 75 BPM)

= Nothing.

What am I missing here?

Have you set Protools to send midi clock?
I don't know how PT works, but in Cubase you have to switch on the sending of midi clock to the right midi out.

Ok I've enabled Midi Beat Clock in PT set to SP. I got the LFO working.. but no matter how much I set the rate (in this case clock div).. it doesn't change the rate of LFO. It stays the same rate (which is very slow for some reason). It does not speed up when I turn the rate knob up. It's just a very slow LFO.

If you set PT to 4/4 (ex in 120 bpm, just to make sure the bpm isn't low), let it run and send midi clock to your SP, if you set the SP LFO clock division to "whole", does the LFO trig every fourth beat then?
If not, with what interval does the LFO trig?
