App Store Description:

Pure Acid is a top quality bassline synthesizer and drum machine in one app! Inspired by classic hardware bassline synthesizers and rhythm machines, which changed musical world back in 80's, like the legendary TB-303 synthesizer, TR-808 / 707 / 909 rhythm boxes and their numerous replicas, Pure Acid is designed to bring back the feeling of retro analog gear in every detail in terms of sound, as well as to provide new functions previously unavailable in the original devices to make your music creation workflow fast and fun! A large number of factory preset patterns will immerse you into an exciting world of Acid House, Techno, Hardcore and Big Beat music genres, which will inspire you to create your own basslines and rhythms for your compositions!
