The Quad Trapezoidal LFO is a single LFO with four outputs. In this module, the four outputs are in step with each other. When the first output reaches it's peak, the next output begins to ascend. And when the first output reaches it's lowest voltage, the next channel begins to descend. When a output is neither ascending or descending it holds it's voltage. The voltage range of all four outputs is +5v/-5V.
There are four knobs which control the module. Each controls the time it takes for the rising voltage of a channel, which also controls the falling time of it's inverse channel, and the holding time for the other two channels. So, by increasing the rising time of channel 1, you're also increasing the time it takes for channel 3's voltage to fall, the amount of time that channel 2 stays at -5V and the amount of time that channel 4 stays at +5V.
