APPEX: Modern Trailer Guitar is a professional guitar library for composers and producers: a playable 8-string guitar, a unique Riff Designer, a riff-playing mode via MIDI and an extensive, fully editable collection of presets — from aggressive metal riffs to cinematic, mysterious sounds in one management ecosystem.
Built for the sound of Doom, League of Legends, Valorant and Call of Duty trailers — or the energy of Imagine Dragons, the steampunk of Arcane, the EDM edge of Daft Punk and Skrillex, the apocalyptic pulse of 28 Days Later and Tenet.

The Riff Designer lets you create, automate, export and import riffs via MIDI, and the riff-playing mode gives real-time control from any controller. Internal and external chains can be used as designed or bypassed for your own processing, and every preset is easy to find, modify and make your own.
