    I put a " flute 1" playing with a bass flute. There's combfiltering all over the place. including replacing the bass flute with a "flute 1"  I provided an audio sample. Flute plays an E4 and bass flute a B3.  Worse than scratching a chalkboard, isn't it? Flute quartets are possible in real life. This happens with many instruments. How do I fix this issue in general. This has limited my options many times with many instruments.

    I do not hear any phasing issues. Am I tonedeaf?

    To describe what to listen for,  it sounds like a third sound underneath the two. Like a faint lower pitch buzzing.

    What you are hearing is the effect produced by playing fifths, that will give a psychoacoustic effect of hearing the octave below.

    If this is not something you want, then avoid held low fifths between similar instruments.

    No, and that isn't comb-filtering.

    Combination tones will be exaggerated if you pass the dyad (two notes summed) through a nonlinear process like compressor or saturator. See:
