The controller from Ray also allows you to adjust the data rate ... but that doesn't mean it'll work with a SSC. But I will say that "I think" the SS flex strips use a higher data rate (on the ray controller) and a lower rate on the modules and nodes (I think) ... so perhaps they might work.
I ordered the 4x5050 (4 RGB LEDS each) square modules which have R,G,Y wiring and they work the same as SS modules, but use slightly more power, so have a max modules limit of 80 to 90 instead of 120 (for the square metal backed modules). I just ordered them and gave them a shot it was a bit of a gamble on my part, but they were TM1804 and not TM1803.
