Steinberg UR44C Problems (M.B. Comp, PITCH FIX)bug?

About Steinberg UR44C Problems ("The Multi-Band Compressor can not be inserted at the streaming mix output stage. ")
I am a beginner.
Sorry for my basic English. Perhaps I can’t reply well or not good response.

Could anyone help me please.

How can I open the Multi-Band Compressor in Steinberg UR44C (dspMixFx UR-C)
According to the UR-C_V3.0_Supplementary_Manual P.16
M.B. Comp is still not selectable in main channel.
PITCH FIX is still not selectable in all channels
Is it bugs?

According to the (UR-C_V3.0_Supplementary_Manual P.8) I can’t see the “output Routing” in my Steinberg UR44C (dspMixFx UR-C)
Is that bug?
I want to setting loopback (Multi-Band Compressor) or do something like Voicemeeter Potato.


I have already watched the UR-C Version 3 Update on Steinberg Audio Interfaces YouTube channel. But something still not working and hard to understand to use that.


firmware version (boot:V1.10) (Main:V3.10)
(TOOLS_for_URC)DspMixFx UR-C V3.10
Yamaha Steinberg USB Driver V2.1.7
Windows 11

Thanks upfront for your reading.

Problem 1 is solved. (from Manual )
( M.B. Comp)change sample rate from 176.4 , 192kHz to 44.1~96kHz.
( pitch FX)change sample rate from 176.4 , 192kHz to 44.1~48kHz.
It will be ok.
