Metal Producer Essentials: Free Metal MIDI Pack (182 files, five tunings)
A free pack of 182 metal MIDI files: 32 drum grooves and fills in 8 styles, 30 riffs across E Standard, Drop D, Drop C, B Standard (7-string) and Drop A, and 5 full song sketches. Every riff and song comes as a full arrangement plus separate guitar, bass and drum parts (songs add lead and harmony). MIDI only, no audio, so you need your own instruments. Use it for anything you like, including commercial work, no credit required. Created by Cinderhall using Jonathan Lachance's own code, custom tools and generators. Make something heavy.
