Double Threshold -> Gate Array

New!

Range controls allow adjustment of any input to be full range. Set one to the lowest input voltage and one to the highest input voltage. Gates can now be set to trigger on up, down or both directions of input signal. 4 trigger outputs enter up, exit up, enter down and exit down give a stream of triggers rather than the individual gates.

8 window comparators with an upper and lower threshold that generate a gate while the input voltage is in the window. There are five modes: link - The lower threshold is linked to the upper threshold of the next window. U/L - Full control over upper and lower thresholds, windows can overlap. 0.05 and 0.1 - Fixed width windows with the upper threshold setting the centre voltage. Good for catching notes. C/W - full Window Centre and Window Width control.

Each mode has an init setting to get you up and running quickly.

In the centre there is a visual representation of the windows. If the lower threshold is higher than the upper threshold the gate will invert and the window will be shown as a gap.

All knobs can be CV controlled for moving windows or for setting voltages to match something else.

Each window has a gate output. The length of the gate depends on the time that the input voltage is between the thresholds. So for small windows or fast moving input signals, the gates are more like triggers and the leds may not light.
