When adding effects to a sound, it's not uncommon to want to apply these effects to just a certain part of the sound. For example, you might not want a complex chorus to affect your bass too much, or a hard distortion to totally fry your high end. Either way, multiband processing adds a dimension to effect chains that really opens up a new world of options in sound design. Multipass helps you with this, allowing you to split the input sound into up to 5 easily tweakable frequency bands and applying unlimited number of effects to each band.
