How to set up Ableton LIVE with SPAT Revolution?
This article explains how to set up SPAT Revolution and Ableton Live to work in Local Audio Path mode.
Hardware setup

In windows, you may have to click on Hardware Setup to select the audio buffer size. - In SPAT, go to Preferences -> Hardware IO, and set up the following parameters:
