Also maybe worth noting, this arrangement did not work. TX-6 Connected to a USB-C Breakout Adapter, I wanted to be able to still charge the TX-6 while using the Thumb Drive, but the TX-6 seems to not be able to agree which device to talk to, the drive, or the MacBook on the other end of the cable to charge it.
But when the cable is plugged into a power brick, no Computer on the other end, its seems to charge and use the drive at the same time.
Also neat and I didn’t read elsewhere yet, but I’m slow, is when the drive is connected and you choose USB in the system menu, it gives you the remaining space on your drive, and I believe how many hours and minutes of audio will fit on it. Mine is reporting 117.2 GB and below the picture of a thumb drive says 115:42
So additional notes because of cable size constraints, the USB-C thumb drive width matters greatly. The Kingston is too wide, the SanDisk is perfect.
