Abx3 is a powerful bass line synthesizer designed to capture the classic acid sound reminiscent of the TB-303. It offers multiple operation modes including host sync for seamless integration with your DAW, an internal sequencer for independent groove creation, MIDI input mode for traditional virtual analog synth play, and an arpeggiator that shifts sequences based on incoming MIDI notes. The synth engine features an oscillator with 32 waveform options plus a sub bass oscillator, paired with a high-resonance low-pass filter to deliver that distinctive acid character.

The effects section enhances sound shaping with eight distinct distortion types ranging from overdrive to fuzz and bit crushing, along with a delay module featuring ping-pong mode and tempo synchronization. A flexible FX rack provides three slots for reverb, chorus, flanger, and additional distortion effects, allowing for rich and dynamic tonal variation. The step sequencer supports up to 64 steps and 32 patterns, each with customizable note, slide, accent, and modulation parameters. Advanced features include parameter modulation sequencing, pattern triggering modes, and real-time MIDI input for live performance and editing.

Abx3 also includes a comprehensive randomizer with 22 customizable scales to inject creativity into your sequences by randomizing notes, accents, and effect parameters. The user interface is resizable and offers five different skins, providing a tailored visual experience. Additionally, the plugin outputs MIDI notes from its sequencer, making it compatible with various formats such as VST, VST3, AAX, and standalone setups. This combination of classic acid sound design, flexible sequencing, and extensive effects makes Abx3 a compelling choice for producers seeking authentic bass line synthesis.
