1) In stereo streaming, the second USB output is named “USB L” instead of USB R”
2) In multitrack streaming, 24 outputs appear in the software, although it is supposed to a 22 outputs audio interface.
For the second point, I guess it’s because the CQ-20B use 24 output audio channels as an audio interface. And it’s probably the same code for the CQ-18T, which sends DAW outputs 23-24 to the Bluetooth channel which, in a perfect world, should have been routed from outputs 21-22 instead.
