Vactrol Low Pass Gate Expansion for the Turing Machine

Out of Stock


The Turing Machine LPG expander is an add-on module for the Music Thing Modular Turing Machine. The TMLPG has four inputs and two outputs – each input goes through a level pot and then to a pair of vactrol based low pass gates, 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 locked pattern.

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