A simple patch demonstrating an example using the BigGraph filter bank. This is a really neat way of controlling the filter resonances using graphical representations.

In this patch I only used the base BigGraph amplitudes with just the one offset. This way of programming the filters reminds me a bit of the Xaoc Devices Odessa Eurorack module (lots of resonant sine waves added together).

As this is for me a deep learning experiment I still cannot properly say I know exactly what I am doing. In this patch I use a few simple formulas (for the first time even a variation that uses multiplication).

Formula U is used to affect the low pass filter cutoff (“oscillator” reconfigured as filter number 5) on the noise signal output.

V is used to route noise to the filter and oscillator 1 to the input of the BigGraph 1. A fixed value of 1 is used to route the output of the filter (in 5) to the BigGraph 1.

Formula B is used to affect the bandwidth spread and A controls the first Offset.

I used three macros, the first to control the reverb (size and damping) the third adds release to the sound. Turning up the reverb and adding release creates a really lush bell like sound.
