Acid Rack 2.0 is a compact virtual analogue synthesizer designed to deliver rich and dynamic sounds with up to 10 voices of polyphony. It features two oscillators capable of producing complex tones through sync, frequency modulation, and ring modulation, allowing users to create a wide range of sonic textures. The synthesizer includes a multi-mode filter offering low-pass, high-pass, and band-pass options to shape the sound precisely.

Sound modulation is enhanced with three envelopes, including two ADSR and one AD configuration, providing detailed control over the amplitude and filter dynamics. Additionally, Acid Rack 2.0 offers two versatile low-frequency oscillators that can operate freely or be synchronized to the host tempo, enabling rhythmic and evolving soundscapes. A host-synchronized arpeggiator adds movement and complexity to patterns, making it ideal for electronic music production.

Creativity is further boosted by two random generators, which can target all parameters or just the oscillators, offering fresh and unpredictable variations during sound design. Acid Rack 2.0 combines a straightforward interface with powerful modulation capabilities, making it a valuable tool for producers seeking classic analogue tones with modern flexibility.
