In this series of live electronics "jam sessions" we try to couple three different systems which embed synchronisation mechanisms at different levels of their functioning. Each system receives audio from the others and tries to synchronisize to the incoming signal. The three systems form the feedback topology depicted below.

Synchronisation in Live Electronics

POZ

In these jam sessions I basically used two FM-based systems.

One consisted of two cross coupled oscillators, the other of six oscillators organised in a 6x6 modulation matrix. Each oscillator's phase is calculated by summing up the phases from all the other oscillators plus itself. Before the sum, each single phase is multiplied by a  so-called modulation index. In the case of the 6x6 matrix I had 36 modulation indexes, whose values were dependent on the phase of 36 hopf oscillators. These hopf oscillators were organised in 6 groups and each group was synchronising to a different input (one of the six incoming signals). Inside a group, each of the six hopfs had a different coupling value.
