UR 44: no direct audio input signal/ hardware monitoring

I’ve spent more days trying to find someone who understands the UR44 and how to use it in Cubase. (I had to revisit the manual to check a ‘casual’ sentence (again) that says the UR44 DSP mixer is usable with any DAW “OTHER than Cubase.” It does not say how you set up, use, and configure the tracks/setting/sends etc to enable control of the Vocal recording level and the DAW music backing tracks level.

My UR22 had a simple ‘balance adjust knob’, so I was able to adjust/hear my vocal going in, whilst adjusting/listening to my music tracks. I had no latency issues. I am now into my 6th week of not being able to get the UR44 to function simply.
I am amazed at the pathetic Yamaha/Steinberg instruction and lack of info/support.
I would’ve thought that, after years of existence of the UR44, the MAIN (pro) function would have been addressed. That is simply recording a vocal to existing music tracks in Cubase. (Something that EVERY user surely does?)
I have run out of patience with (non=Steinberg) tutorials and manuals, NONE of which address this. Why haven’t Steinberg?
I have gotten to the stage where it appears I need to set up additional GRP, FX, Busses, Hardware tracks etc in order to control the UR44 from within Cubase to simply hear myself when recording vocals.(???) I am not the best at technical issues regarding recording but I am good at my English and learning. Does anyone know where I can find a simple Overview of how to set up and use this over complicated way of monitoring. If the answer is to slow down my workflow, instead of tweaking a “Balance knob” as in the UR22, then I guess I’ll have to sell the UR44, as it’s too late to send it back.
Please, can someone…, anyone… help, or direct me to some sensible, logical straight forward answers.
Thanks. John
