The Mod Matrix in the Quick Sampler is the function that facilitates dynamic sampling editing. This feature allows users to create complex modulation routings by assigning various modulation sources to different parameters. For instance, you can set up modulation to control pitch, filter frequency, or other parameters based on the incoming audio signal's characteristics or controlled by MIDI. This provides a powerful way to manipulate samples dynamically in real-time, offering more expressive control over the sound.

In contrast, pitch adjustment affects the tonal quality of the sample, while amplitude control relates to the loudness or volume aspects, which, although important, do not fully encapsulate the dynamic editing aspect that the Mod Matrix provides. Visual waveform editing allows for precise cuts and timing adjustments but lacks the real-time modulation capabilities that the Mod Matrix offers.
