GarageBand

GarageBand is a digital audio workstation for macOS, iPadOS, and iOS that allows users to create music and podcasts, its systems enabling users to create multiple tracks with pre-made MIDI keyboards, pre-made loops, various instrumental effects, and voice recordings.

Anthony Padilla used GarageBand to produce the music for "Hardcore Max", which he revealed while he and Ian Hecox were watching the song's music video in fourth episode of Watching Old Videos.
