I have pitch recognition through the cochlear if I listen really carefully and the notes are distinct and about half an octave apart. Less than that & it’s tricky. Certainly, the nuances of an ensemble playing together with the notes mashed together is not possible. When I had a hybrid acoustic/electric component for a few months, it was better but still not perfect. I definitely don’t have enough pitch definition to play an unfretted instrument like a cello. Even piano would be hard, but I could give it a go, stay roughly to the right key and call it jazz! 
Using my good ear only, cello is possible in an ensemble. It’s just really hard without the other ear to listen to others.
There’s also a big difference through the cochlear between rock music with a definite best and fewer instruments vs classical music with a less definite beat and complex harmonies.
I span genres from classical to jazz to pop to modern worship music, across guitar, keys (acoustic piano, electric keyboards, etc), cello, & percussion. I do play purely acoustically now when needed, but try to offload to others if possible & reserve my performances for IEMs if possible.
I also do live sound engineering. This is still possible. However, judging overall volume is very difficult & I rely much more on my sound pressure meter than I did in the past.
