PaSSBot is a stochastic filter bank audio processor, the sound designer's chisel !

PaSSBot is a unique stochastic filter bank audio processor. The desktop VST/AU version of PaSSbot has already arrived in February 2020 and this iOS version is equivalent to the latest version 2.1.

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

The user can set values of center frequency, gain and resonance of the each filter, which will be then eloborated with powerful stochastic generators ( 4 independent GENs for each filter ) with continuous or discrete probabilistic distributions but also with standard waveforms.

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

Precision DSP rendering, less than 1milisec. control rate precision.

The filters can run continuously or be triggered manually. In that case, each filter will be applied an independent AR envelope with configurable random duration.

Important notes :

- A recent iPAD model is being recommended and also setting the host buffer size to 128 or higher greatly helps to the CPU needs which also heavily depends on the number of parallel filters being used.

- The resonators can be sensitive to input signal level.

- The PaSSBot manual can be found at this link.
