I wouldn't have worded it that way….."convenience" algorithm. Diatonic and QuadraVox offer a different set of delay features for intelligent pitch shifting. Diatonic has 2 voices, but has independent control over the delay and feedback of those voices. QuadraVox loses the independent delay control, and all feedback controls, to give you the 4 voices. With no pitch shifting, Diatonic could function as a dual feedback delay algorithm, whereas, QuadraVox is more of a 4-tap multi-tap delay algorithm.
