The basic idea of subtractive synthesis is similar to making coffee: something goes through a filter to remove unwanted components from the final product.

////////////////////////////////////////////////////////////////////////////////////////////////////
Use LPF, a low-pass filter to subtract high-frequency content from an input source.
⧉ ✔
////////////////////////////////////////////////////////////////////////////////////////////////////
RLPF, a resonant low-pass filter, removes high-frequency content and emphasizes the cutoff frequency.
⧉ ✔
////////////////////////////////////////////////////////////////////////////////////////////////////
Resonz is a very, very, very strong filter. Use it to emphasize a frequency band.
Transform noise into pitch with a sharp cutoff.
