Pre DAW(Digital Audio WorkStations) in the old tape days it was customary to get a recording as close to,"Clipping as possible because of the S/N(signal to noise) ratio of the tape media.This is not such a concern these days as digital recording allows much more,"Headroom" e.f it's much more forgiving.
Mixcraft,like other digital recording systems,allows virtual noise free and little or no perceptible quality loss manipulation of recorded material.Getting sound levels between different parts correct is just a skill to be learnt as we all have different setups.
