Acid House and Acid Techno (often referred to simply as "acid") emerged in the mid-1980s, driven by the unmistakable squelching sound of the legendary TB-303 bass synthesizer. Inspired by this iconic sound, 303 Acid Lab by Apollo Sound delivers a powerful collection of acid loops designed for modern producers.

Created using the original TB-303, alongside a wide range of analog and digital synthesizers, this pack offers a versatile selection of classic and modern 303-inspired sounds.

Inside, you'll find over 100 evolving acid basslines, synth arpeggios, and sequences packed with dynamic filter movement, resonance, and attitude. Every audio loop includes a matching MIDI file, giving you complete creative control and the freedom to recreate or customize the sounds using your favorite synthesizers.

As a bonus, the pack includes custom 303-style presets for Xfer Serum, NI Massive X, Vital, and Spire, ready to inject instant acid character into your productions.
