Sour Acid Vol. 1 - Vicious 303 Acid Lines, MIDI & Ableton Instrument Rack

Sour Acid Volume 1 – A raw acid toolkit inspired by the legendary Roland TB-303.

Built for producers who appreciate movement over precision. From fast, modern techno to stripped-down 90s flashbacks, this pack delivers texture, motion, and bite. Everything is designed to be twisted, automated, and re-shaped—no two takes need to sound the same.
