FLIGHT OF HARMONY SINNER

Sinner is based on a sine-shaping circuit that applies logarithmic distortion to the input signal, causing ramp, saw, triangular, and similar, signals to be more rounded and approximate a sine wave. Pretty freaking boring when you read it like this, so it has a few extra features that allow you to twist and wring your signal into much more excruciating and exciting shapes. Part of this is accomplished via a four-quadrant multiplier (4QM), which also offers ring modulation (RM) as well as typical voltage-controlled amplifier (VCA) capability. Sinner is direct-coupled (DC) all the way through, so you can use it to control and process control voltages (CV) and other DC signals in addition to sculpting audio. If, after blowing a few speaker cones, you decide you’ve had enough of that fun, it also has a full-bypass toggle switch to change the output to capacitive coupling (AC) and block the DC bias from the signal. The LED above the switch is lit in DC mode, and off in AC mode. The output L
