Take a moment to consider your Intelligence and Wisdom scores, as well as your spell inventory before proceeding further. You have seven spells at your disposal…

Will you cast “Length,” which controls the decay length of the reverb?

What about “Diffuse,” which adjusts the spread of the reverb? With your wand (or just the knob) turned counterclockwise, the reverb is sharper with more attack, resulting in a stuttering sputter of individual early reflections. Clockwise casts a washy, more ambient-sounding hex.

Overwhelmed by fear, you hastily cast “Dampen!” As you shout the incantation, you notice that a counterclockwise variation of this spell results in brighter tones, while as you rotate your wand clockwise; you hear darker tones with a mellower top-end. It’s almost as if your magic changes the hardness of the cavern walls, and thus the tonal characteristics of the reverb!

Elsewhere in your book of magic is “Drag,” which separates the individual digital delay lines, literally dragging them through the very fabric of time and space towards an unknown event horizon from which they may never return. Clockwise “Drag” positions will gather the delay lines close together for a more reverb-like effect. Turn the “Drag” counterclockwise, and the delay lines will begin to pull apart for a scattered ping-pong delay effect.
