Joseph Casbaria’s Sequential Resonation Machine manipulates amplified sound via a (very custom) 12-position rotary switch on the console’s face –
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 (4â€™ pipe). The result is a very simple sequencer, using pipe resonance to produce pitch.
