Spooky2 can only do 1 biofeedback at a time. To do multiple, you need multiple spooky2 setups, that is, 2 laptops with each running Spooky2, and 2 GXs.
There is no way to use 1 laptop and 1 GX to do simultaneous scans from each of the GX generators. Also, not even 2 laptops and 1 GX will work. You need complete separate setups as described in the first paragraph.
