[citation needed] In 2016, Optical left a YouTube comment stating, "Half the drums were my original recordings of drummers I know...other half were taken from 70's funk tunes and resampled many times to get them to sound unique and solid...none of them were sped up as I always cut my drums into individual hits, reprogram them in my sequencer and use them at original pitch to keep their chunky sound intact.
