Let’s postulate cross-breeding Polyphony code with the Diatonic / QuadraVox genetic sequence.  Perhaps even SIFT-ing that concoction through the HarPeggiator.  Yes, Frankenstein’s laboratory would be working overtime to create this new lifeform.  But if successful, a scale-constrained monster sequencing algo that pushes the limits of Spectral Instantaneous Frequency Tracking.  Nobel Peace Prize nominee for audio physics.

And no breaking with backward compatibility for any existing algorithms.  Just sayin’.  A fella’ can dream …
