4. Algorithm

Trópos DSP algorithm is built around two sine oscillators, which recursively cross-modulate each others phase. The way in which this cross-modulation happens is mainly defined by a 6x3 feedback matrix, which also defines the way in which the microphone signal affects recursion.

Software Framework: Strip

Tropos was developed using Strip, a software framework for designing, and experimenting with, feedback relationships in recursive phase modulation sysnthesis.
