Overview

FreeOhFree is a meticulously crafted software recreation of the legendary 303 synthesizer. Delivering the authentic squelch, slide, and character of the original acid machine, FreeOhFree combines classic analog modeling with modern workflow enhancements. From deep sub-bass to screaming resonant leads, FreeOhFree captures the soul of the 303 while adding powerful pattern management, scale quantization, and flexible MIDI capabilities.

Featuring authentic ladder filter modeling, analog-style drift and character, 512 pattern storage slots, 12 musical scales, and comprehensive MIDI control with MIDI learn, FreeOhFree is the ultimate tool for acid basslines, vintage house grooves, and experimental electronic music production.
