Probability Router 521

Also available in The Probability Router Bundle!

Introduce some controlled chaos into your creations - great for unpredictable switching or morphing between different sound/cv sources! Probability Router 521 randomly selects one of the five mono/stereo input signals and sends it to a single output.

A new input is selected every time the Trigger input receives a positive signal or the trigger button is pressed. The probability of each input is set by the Probability sliders. Only the relative positions of the sliders matter, so setting them all to 1 is the same as setting them all to 100. Each probability can be modulated with the corresponding CV In jack and knob. Enabling the Force Switch button selects a new input every time, so that the same input is never chosen two times in a row.

The A(ttack) and R(release) sliders set the time it takes for the selected input to open and for a non-selected input to close. Quick (above zero) attack & release times help prevent clicks in audio when switching inputs, while longer ones can create interesting movement in drone/atmospheric sound generators. With bigger A & R values, the signal from several inputs can be present at the output at the same time.

The Up & Down buttons cycle through the inputs manually, and you can also click the input level meters to switch to a specific input. The switch next to the Trigger jack enables/disables incoming trigger signals. These can be handy when you are in the building/debugging phase and want to test different signal paths.

Inputs with neither jack connected will be left out of the random selection.

Tip: You can also set the attack & release times by (double)clicking the sliders or the value display. Type in the time value in ms, or add "s" for seconds.
