About this demo
This page steps beyond the 1-operator case. Here you can switch between parallel and serial relationships, then add feedback to operator 1 and listen to how the tone changes.
In serial mode, the main active pair is built from the first and third operator slots on channel 1, matching the way ymfm wires the internal 4-operator flow. In parallel mode, the same two slots are left audible as separate carriers.
