Audio Realism - ABL2x-Redux v2.9.1.0 STANDALONE, VST, VST3 for Windows

• Component-Level Circuit Modeling: Recreates the non-linear interaction between the discrete oscillator, diode ladder filter, envelope decay circuits, and power-rail sag of the original 1982 hardware unit.
• Classic Dual Waveform Oscillators: Switchable Sawtooth and Square waveforms shaped with the characteristic asymmetrical clipping and phase offsets of the original analog circuitry.
• Authentic 18 dB / 24 dB Resonant Diode Ladder Filter: True-to-hardware resonance behavior, retaining thin resonant squelches and low-frequency attenuation when resonance is pushed to self-oscillation.
• Accurate Slide & Accent Physics: True capacitor discharge emulation for legato slides and accent punch, reproducing the signature pitch and filter ducking/blooming response.
• Integrated 16-Step Classic Sequencer:
  • Full emulation of classic Time/Pitch write modes.
  • Step transposition (Up/Down), Accent flags, and Slide ties per step.
  • Pattern Randomizer / Algorithmic Generator for generating instant acid riffs.
• Integrated Drive & Distortion Stage: Built-in multi-mode distortion unit with Drive and Tone controls to produce aggressive, overdriven industrial acid lines without external plugins.
• Flexible Playback & DAW Synchronization:
  • Host Sync Mode: Locks internal patterns to your DAW's master tempo and transport.
  • MIDI Mode: Play ABL2 as a standard monophonic synth directly from your DAW's piano roll or external MIDI keyboard.
  • Drag-and-drop pattern export to MIDI clips.
• Redux Framework Enhancements: Resizable high-resolution vector interface, selectable color themes (Classic Silver and Acid Yellow), and native 64-bit VST3 architecture.

The Sound of the Acid Revolution
Released by Roland in 1982 as a practice tool for guitarists, the TB-303 failed commercially before being rediscovered by Chicago house and European techno producers. Its peculiar diode ladder filter, idiosyncratic accent response, and glide capacitors transformed it into the defining sound of acid house, trance, techno, and big beat.

AudioRealism Bass Line 2 (ABL2x-Redux) has long been considered one of the most sonically authentic virtual models of the hardware 303. By mathematically modeling the exact transistor configurations and voltage interactions, ABL2 captures the raw, organic squeal and elastic bass groove that generic digital subtractive synths cannot replicate.

The Redux Upgrade
The Redux revision updates ABL2 for modern production setups:

• Upgraded 64-bit DSP engine with anti-aliasing oversampling.
• Dedicated Standalone executable and native VST3 integration.
• Resizable user interface with classic silver and high-contrast acid-yellow layouts.
• Fast pattern creation tools, including an intelligent acid riff generator with scale snapping.

Synthesizer Parameters:

• Waveform Selector: Switch between the buzzy, hollow 303 Square wave and the bright, biting Sawtooth wave.
• Tuning: Master pitch fine-tune dial (±12 semitones / cents calibration).
• Cutoff Frequency: Sets the baseline frequency cutoff of the 4-pole diode ladder low-pass filter.
• Resonance: Sweeps from clean sub-harmonic filtering to sharp, screaming self-oscillation.
• Env Mod: Controls the depth of the dedicated envelope generator applied to the filter cutoff.
• Decay: Sets the decay time of the filter envelope (short percussive clicks to open sweeps).
• Accent: Controls the extra volume and dynamic filter modulation burst applied to flagged steps.
• High-Pass (HiPass): Calibrated high-pass filter switch for removing subsonic rumble.

Sequencing & Performance:

• 16-Step Pattern Sequencer: Fully editable step grid with step length selection (1 to 16 steps).
• Pattern Controls: Pitch, Octave Up/Down, Accent On/Off, and Slide On/Off.
• Pattern Generator: Algorithmic randomizer that generates musically coherent acid basslines based on defined density, accent probability, and scale constraints.
• MIDI File Export: Drag completed patterns directly out of ABL2's interface and drop them as standard MIDI files onto DAW tracks.

Plugin Profile:

• Supported Formats: Standalone Application (SAL), VST2 (64-bit), VST3 (64-bit)
