Tesseract Modular - Selecta
Selecta - with reversible panel
This module has 4 channels of OR Combiner and 4 channels of A/B Switch.
This new version has a reversible panel, so the switches can be placed on the left or the right side.
The OR Combiner is conceived to select or sum trigger and/or gate signals, each channel has 2 inputs (A & B) and one output. A switch select which signal would be present at output, being the middle position of the switch the sum of both. It could be used with other type of signals but only the positive part of these would be present at the output stage (with a small lack of voltage because of the diodes and the pulldown resistor), so it could work with envelopes for example. With bipolar voltages the OR COMBINER channels will work as a Half-wave rectified output (the negative half of the signal is clipped to 0V) This can add many harmonics to audio signals, the combination of 2 oscillators will give as result a sort of 'ring modulator' sound.
The A/B Switch selects between A and B and the middle position of the switch is a "mute", works with any kind of signal (cv or audio) and is bidirectional. Can be used with 2 input signals and 1 output or 1 input signal and 2 outputs.
The circuit of the first version has been re-designed to avoid the bleeding among other issues.
