| Sequential Resonation Machine |
Created by Joseph Casbarian, the Sequential Resonation Machine routes any amplified sound source through a twelve position switch located on the top of the unit.
This switch is controlled by a variable speed DC motor. The signal path is accessed from the patch panel via switch jacks in the center of the panel (2 jack groups).
Next, the user can patch the switched signals into any one of the pipe jack multiples (4 jack groups).
From these outer jacks, the signal is sent to separate speakers underneath each of the twelve pipes spanning an octave C# 4 up to C5 (4’ pipe).
The result is a very simple sequencer, using pipe resonance to produce pitch.

The variable speed motor spins the center metal contact bar like a propeller, which in turn touches the contacts, switching the sound on and off, depending on how the signal paths were routed via the instruments center Patch Panel.
