My first post here. Sorry if this has been answered, but I searched online and couldn’t find the answer. I have my AK, RYTM, and Heat hooked up via Overbridge directly to the USB ports on my old iMac desktop (late-2009 model, 2.66 GHz Core i5, 8 GB RAM) running OS-X Yosemite. Will I see a marked performance and stability improvement if I get Overhub? If so, will Overhub work with an old USB 2.0 enabled computer such as mine? If not, should I get a good quality 3rd party USB 2.0 Multi-TT hub such Belkin? Or is hooking up the Electron devices directly to my computer (as I have now) the best way to go? Thanks!! 
Overbridge will work fine, just as any MTT hub.
