Allocate a synthesis voice. This function is called by a soundfont's preset in response to a noteon event. The returned voice comes with default modulators installed (velocity-to-attenuation, velocity to filter, ...) Note: A single noteon event may create any number of voices, when the preset is layered. Typically 1 (mono) or 2 (stereo).
