Here you have a simplified diagram of an advance modulation synthesis algorithm. The DSP algorithm uses 2 stages of FM, 1 stage of AM and an intermediate stage of Chorus modulation. Keep in mind that the FM here is adapted to the NoxSiren internal module structure and the Chorus modulation unit is not the classical Chorus structure where the modulator is a LFO. You can build this algorithm using NoxSiren.
