don't know how you would / if you can go about syncing the tempo of a preset though SPDIF to the eclpise, isn't that for syncing the digital audio?
To sync the tempo of the effects, I have done this via MIDI, where you set the ECLIPSE to sync to MIDI clock and you would tell ableton to send out MIDI Clock. I have not used ableton personally, but MIDI wise I assume it is the same as other DAW's
