B-Line 303 is a bass-line synthesizer that captures the vibe and sound of classic EDM and Acid techno synthesizers from the 70s and 80s.

B-Line 303 can easily dial up the classic Acid bass sound with all the squelch and buzz of the original classics. New in Version 2 was the Pattern Control Filter (PCF) that adds iconic Acid style tweaks to the sound. The PCF allows any MIDI pattern to be manipulated into an almost infinite pallet of Acid goodness. New in Version 3 is the optional Groove Sequencer that can add additional retro feel to your tracks.

Comes with 50 presets to get you started but has room for up to 200 presets. B-Line 303 also comes equipped with an improved Stereo Doppler Chorus effect (pitch shift/chorus effect) and a Stereo Echo effect to complete the total old school Acid bass-line experience.


  • 200 user presets, 50 custom presets.
  • Pattern Control Filter, Groove Sequencer.
  • MIDI automation.
  • Doppler Chorus, Stereo Echo effect.
  • VST 2.4.

No free plugin anywhere to be found. Link is disappointingly out of date like most of the links on here.
