Hi there,
On Windows the first step is to install a virtual MIDI device like MIDI yoke or loopMIDI.
After that all steps are the same: select a virtual bus as the output for Sensory Percussion and the same virtual bus as the input for SD3, then load the template .sps in Sensory.
If you (or others reading this) happen to use the Sensory Percussion Ableton Plugin, as well as the SD3 plugin, I think that this template: Sensory-to-SD3-Project.zip (361.7 KB) should work for you (regardless of on Mac/Windows). Just train or load usermodels in the Sensory Percussion plugin, and then you should be good to go.
Let me know if you have any questions or run into any specifics snags using either method.
Best,
