What is PaSSBot?

A Cloud of Filters
with Organic Character

PaSSBot is a unique stochastic filter bank plugin. A cloud of filters with complex modulation capabilities driving up to 64 unique parallel instances.

It is also structurally the base of sonicLAB Fundamental, where the latter owes most of its features to the PaSSBot.

PaSSBot filter types are Biquad, StateVariableFilter, Ladder, Resonator and SEM filter implementations. With behaviors of bandpass, Lo + Hipass, and Notch types and up to 64 of them in true stereo!

PaSSBot has a rich time domain modulation scheme at your finger which operates on various parameters.

Stochastic Engine

Individual Behavior
or Harmonic Relations

You can set each filter parameters individually, but also distribute them in harmonic order. The harmonic spread ratio can be set by the user or even modulated by a GEN.

Be it stochastic complex control-waveforms to interact with or simple touches, this calculated data serving to the filter bank creates musical soundscapes instantly.

Tuning scales can be deployed to tune the filter center frequencies.

Tremendous Sonic Calculation

4 independent GENs for each filter (modulation generators) with loads of stochastic distribution sources. This makes up to 64 x 4 GENs running in parallel.

Features

Precision
Filter Engine

  • Multi-Parameter Modulation Each GEN can modulate a different parameter: center freq, filter gain, filter bandwidth, harmonic spread ratio and stereo spatialization.
  • Musical Scale Tuning You can tune the filter frequencies to musical scales. PaSSBot can read .scala format scale files.
  • True Stereo Imaging True two channel behavior for stereo imaging, and each filter position can be modulated on the stereo field.
  • Triggered or Continuous The filter can run continuously or be triggered manually. Each filter will be applied an independent AR envelope with configurable random duration.
  • Precision DSP Rendering Less than 1ms control rate precision and at the same time CPU friendly.

PaSSBot v3 is available for OSX, Windows platforms as VST3, AU, standalone formats. Also PaSSBot v2 is available on iOS.

All sonicLAB products are 64bit only.

Recommended system: OSX Catalina or higher, Windows10 or higher. Apple Silicon M1 1st gen. equivalent or better.
