Korg Mono-Poly Synopsis

Per the name (a.k.a. MP-4), either a reasonably equipped monosynth or a 4 voice polysynth with different waves for each oscillator.

Voice architecture is 4 osc subtractive with white noise (i.e. VCO1+VCO2+VCO3+VCO4+noise->VCF->VCA). Sync and cross-mod are also provided. Three voice modes are provided (unison, poly, unison/share)
