There’s a world of fun to be had with two MF-102s…

Great demo. Thanks for posting.
Thanks for posting ! i think Ring Modulator is great, and I am seriously evaluating to purchase another one !! 
2 ring mods could be very tempting, but I found it a little odd that you achieved stereo without really using each of the outputs to your mixer. (Or did you? I couldn’t really tell from the video) But would love to see more videos when you make them!
Headphones,
I sent each output to the mixer. You can really hear it when the CP-251 is sending 180deg out-of-phase LFOs to each of the 102s (at about 2:05).
The back panel shot may have been a bit confusing. I didn’t show all the connections so it was easier to see the CV connections.

i always wanted a second 102, now i NEED a second 102! the stereo tremolo was just amazing
Lets see some multiple freqbox tricks now 
Thanks for all the great comments. I’ll see if I can come up with some stereo FreqBox applications. Until then, this MF-101 application would also work with the FreqBox…

You could use two FreqBoxes, run a stereo signal through them (one for left, the other for right) and send the ENV Outs from each to two separate synths.
