Mixing a Grand Piano in a Rock Mix with guitars, drums, bass, vocals.

Hello, I need some advice on mixing cello and piano duo. I am using sampled technology, but the problem is that I can't find any settings for cello or piano positioning, mixing etc. How loud to be the piano, which position to be simulated for it, the same goes for the cello.

hello, i am a new one in recording...i play piano and sing..can anyone give me some advices how to record just a piano track and how to mix that it sounds good. (mic positions, pan, effects, reverb, ).

Any tips on mixing piano? The source is a Korg 01W so I don't have to worry about mic placement. I just want to avoid a muddy bottom.
