Let me mention one seemingly off-topic idea. I've been back into synthesis for only about seven years now. In that time, I've observed that analog and digital synthesis each have different effects on my music making; one I like, and the other I definitely dislike.
On the old DSI forum, Namnibor once made a remark that totally irritated me; yet it turned out that he was correct, and in the end, he helped me to understand something. He said I should realize that much of the music on my YouTube channel more properly belonged in the ambient category, rather than the classical. Ouch! It struck a nerve, alright, because that's the last thing I wanted, and yet it was true.
My point concerns only the limited digital capabilities of the Poly Evolver Keyboard. I've found that digital synthesis sends me in a musical direction I don't like and didn't want. I have no interest in producing ambient electronica - none whatsoever. The music I want to produce is centered on the fundamental elements of melody, harmony, rhythm, counterpoint, and traditional hymnic voice-leading. It strives for a theme and its development, follows a form, and often turns to imitation, canon, and fugue. Thus, it's not only emotionally satisfying, but also, intellectually. But when I program sounds using the digital side of the Evolver, I always find myself drifting away from such musical elements, and instead, swimming around in the slow, dark, and amorphous universe of ambient synthesis. Hence, the "ethereal pad" - this mysterious lumbering phantasm that drifts in and out, forming a lethargic triad here and there, but seldom rising to a definite musical theme or form. Sure, it's fascinating for a time, but it's the opposite of what I wanted to do with music and what I'm determined to do with it in the future.
On the contrary, I've found that analog synthesis directs me just where I wanted to go. Its pure, raw, direct, and un-nuanced character affects me like a traditional musical instrument, especially the organ. I find myself writing themes and developing them, following coherent chord progressions, and using the counterpoint I've always loved. In other words, I far prefer the musical influence that analog synthesis has on my creativity and would even call it "wholesome" and "healthy;" whereas, I need to be wary of the influence that digital synthesis has, because it leads me to a substantial degree of musical laxity and futility.
This is just one of the several reasons I far prefer analog to digital: musical influence.
