The digital section offers a diverse palette of sounds, from fat synth waveforms to crisp metallic timbres and beyond. Digital sounds can be routed through the analog filter, instantly adding organic richness. Massive hybrid sounds are also possible by using both engines together. For example, use Poly Stack mode to layer the four analog parts for richness and body, then add digital tones on top for extra spice.
