Good gracious, 'The Craft of Musical Composition: Book 2' by Hindemith has achingly specific instructions on what exactly to do within melody-crafting. Frankly @nickgreenberg, I'm impressed that you can recommend a book like this. I'm just trying to craft a system that won't get me booed off the dance floor. Thank you, I've ordered a copy and I'll see what I can make of it.
I imagine contrary motion will be somewhat more difficult to pull off with something like the Metropolix, but I think I could put together some oblique counterpoint in a fairly non-complex manner. I'll have to do some testing, and some deeper research into counterpoint music theory.
Running the Maestro through a quantizer like Scales is something I hadn't thought of, excellent. Let me see if I can fit in a Switchblade and Scales to switch between the Metropolix and the Maestro; that could provide me with some momentary controlled contrary motion before switching back to the oblique and (hopefully short) moments of similar motion.
Your post doesn't read as condescending in the slightest, quite the opposite; it has been intensely helpful. One of my weaknesses is my novice grasp of the theory behind music. I appreciate any tips others have to offer, so again, thank you.
