The SIM-CHAU is a synthesiser focussed on simulating a Chau gong, otherwise known as a tam-tam, Chinese or symphonic gong. My SIM-GONG also simulates this type of gong, but my good friend and DSP God Martin Vicanek created an amazing set of 256 bandpass filters which use very little CPU and I think sound considerably more convincing than my original resonant comb filter approach.
This is not a replacement or version 2 of the SIM-GONG because that can make tuned or bell-like gong simulations whereas the SIM-CHAU engine is better at simulating the more chaotic Cymbal-like sounds.
