Like a true production Jedi, Virtual Riot has mastered the ways of Serum. His expertise in synthesis, effect processing, sound design, and studio wizardry all come together in this wonderful array of presets and new sounds. The demo-track uses only presets from the pack with no further processing (just some light instances of mastering with iZotope Ozone 8), and all the drums source from Virtual Riot's sample pack earlier this year.
