BZ-SEM

The expander module of 1974: two oscillators and a filter that sweeps from low-pass through notch to high-pass.
What is modelled.
Seven circuits. The filter, the amplifier, both envelopes and the modulation oscillator are entered from the factory schematic.
Its trimmers are set the way the owner's manual says to set them, by running the adjustment procedure on the model.
