A bit of info on why, just to get that out of the way. My studio is in transition. A Lenovo laptop with an i9 10800 2.4 gHz CPU with two TB3 ports is running my software, Cubase 15, Wavelab 12 and Spectralayers 12. No other Daw software other than UAD vst, Slate VSX, Toontrack SD3, EZ Drummer 3 plugins are installed and authorized.

I normally am interfaced with a Rev 1 HDSPe MADI card in a Sonnet PCIe>TB3 chassis and life is good.

I have been ill recently and literally need to work from my bed so I have interfaced my 2020 Babyface Pro fs to one of the TB ports of the Lenovo and it is working. I have an external, high speed USB3 hard drive interfacing the other TB port on the machine. Cubase, Wavelab and Spectralayers all load and stream audio. Totalmix buffers are set to 2038 samples. All of these software installs are new and I have not yet been able to test them via TB3 in my normal setup so I’m flying blind with the Babyface on TB.

I am testing this by using Hear.com (Plugin Alliance) in the last output insert and VSX as the insert before that in Wavelab Pro 12. The reason VSX is before the Hear.com plugin is because the Hear.com plugin is corrective. I am a 75 yo guy with hearing deficits and this is like a dream come true. I can hear as clearly as I did in my 20’s. It is amazing. It also is extremely CPU intensive and Wavelab will start streaming but the controls freeze and I have to Cntrl>alt>delete to close out. I want to believe that I won’t have this issue when I can access my MADI/TB3 chassis.

Thanks for reading this far. My question is, since I cannot access my Sonnet TB chassis, does interfacing a USB3 connection to a TB port throttle the I/O streaming capabilities in excess of 10 MBs?
