Venom VB-303 VSTi (Beta) – A Freeware Acid Spitting Synth!



Freeware goodness in sight! Behold the Venom VB-303, a software synthesizer inspired by the famous Roland TB-303 bass synth. This plugin, currently being developed by the KVR Forum member antto,  follows the sequencer based workflow of Roland’s silver synth, so don’t expect anything else than working with patterns here. And that’s exactly the way it should be, old school for the win. Besides that, it is amazing that a plugin which sounds and looks so good can be released as freeware!

Keep in mind that the software is still released as Beta, and that the developer suggests you don’t use it in any important projects before the final version comes out, because it won’t be compatible with the current release. For the same reasons, I won’t review the plugin just yet, this article is just a heads up for everyone to be aware of the beast that’s coming their way.

Make sure you read the manual before using the plugin, so that you get familiar with the way it’s supposed to be used. Not that the workflow is complicated or anything, but it’s pattern based and probably not everyone will find it self-explanatory. Also, don’t forget to protect your face before testing the plugin. It will easily attract you with it’s gorgeus looks and then suddenly start spitting the very devil’s acid venom all over your studio. Word.

      heh ;]
      unfortunately, it seems that the dev stopped working on this plugin. but even if it remains unfinished it’s still a great tool, i love using it!

      that’s great news! i haven’t seen any news about it for a while, so i figured it’s not being developed anymore. can we see some more info about the current progress somewhere or is it top secret? :]

  1. Pretty good plug in. Hope the rewrite has a bigger interface so I don’t have to have my face against the screen. Must be what the warning was for.

  2. wow now we just need a dedicated, headless (no monitor required) physical interface to completely control the software and we have a soft-303 .. can you imagine a physical representation of the GUI? that’d be so fucking awesome.

      afaik, antto is working on a new version which will be fully controllable with (almost any) MIDI controller.

  3. the current version of VB-303 was redesigned, i threw away the old ideas and decided to stick to making this thing work like a x0xb0x on the inside, and look and behave like a 303 on the outside

    the sequencer interface is basically TB-303 style, with some touches.. so anyone who has programmed patterns on a real 303 would be familiar with Venom
    there is internal sync mode (Venom sticks to host bpm) and external (midi sync) so now you can sync this thing to your hardware drum machine

    lots of improvements in the synthesis, thanks to a number of people and my x0xb0x (which is still with it’s guts out)
    so it no longer sounds “silly”

    i haven’t stopped, i love this thing too much

  4. Does it work with Maschine 1.7.2 ?

    Seems to open up alright but cant get a sound out of it.
