303 Emulator Features ABL3 Engine
Image placeholder title

Get ready for a new summer of love with ABL3 - the brand new 303 emulator from Audio Realism!
The original 303 was the silvery box that spawned a whole genre of dance music in the late 80s: Acid House. Ever since, the 303 has been increasingly hard to come across, and absurdly priced once you find one.

Now, ABL3 is here to fulfill all your 303 wishes, with a super authentic 303 modeling, built-in sequencer and adjustable modeling settings to add just the right amount of analog quirkiness to your next acid floor filler. And as usual–you can try ABL3 before you buy. For 30 days, in fact.

Product details
ABL1 was released in 2003 and became quickly one of the most popular 303 emulations as a VST plug-in. ABL2 improved on that and was released 2007. ABL3 is the latest version of our 303 emulation platform.

The ABL3 engine is a complete rewrite and has been in development for many years with the single goal of making the most authentic 303 emulation possible. With ABL3 we hope it will set a new benchmark in analog emulation.


  • Extremely authentic 303 emulation using our ABL3 engine
  • Ultra natural knob response, scaled to match the original 303 precisely
  • Built-in 303/Rebirth style step sequencer with 64 steps
  • Hard sync to the host's transport
  • Supports 4 patterns of 16 steps, 2 patterns of 32 steps or 1 pattern of 64 steps
  • CV/Gate input to control the sound engine externally
  • CV/Gate output to control other Reason devices from the step sequencer
  • CV Modulation inputs for Tuning, Cut Off, Resonance, Envelope Modulation, Decay and Accent
  • Resonance and Gate Time trimmers that allow tweaking the emulation
  • Three different VCO Models
  • Noise settings for VCA Clicks and VCA Noise
  • Pattern modifiers with Random, Alter, Copy and Paste functions
  • Unique vibrato which is activated by setting UP+DOWN on steps. This effect is one of the few extensions to the 303 that we are launching ABL3 with.
  • Full 48 and 96kHz support, which means the engine uses the full bandwidth of the project setting
  • Step Record mode which allows recording patterns via MIDI or the On-Screen Piano Key
