Turing Machine LPG Expander

Expander which adds 8 vactrol LPGs to the Turing Machine (Black and gold panel)

The Turing Machine LPG expander is an add-on for the Turing Machine with four inputs and two outputs. Each input goes through a level pot and then to a pair of LPGs, one which goes to the left output and one to the right.

The module connects to the Pulses output on the Turing Machine and each LPG is pinged when the corresponding LED on the Turing Machine is activated. Three Variation switches are included which use a logic circuit to alter the pattern for eight different variations on the basic pattern.

The length of the clock input to the Turing Machine changes the length of the ping received by each LPG, from short plucks to fully open. The module uses NSL32 optocouplers for a long, natural decay.
