This module allows you to draw a waveform through the use of 16 sliders which determine the breakpoints of the wave segments. It has a poly CV input that allows you to control each slider with a voice of a poly signal, using for example the LF Noise module. This makes it easy to create constantly changing waveforms for timbral variation. There is a button and a CV input to randomize the values of the sliders when they're not being controlled by the poly CV, and a button to return them to zero (these won't have any effect when using a poly input to control the slider values). To strengthen the bass frequencies, a suboctave triangle oscillator is added to the signal, and its level can be controlled with the blue knob. There is an output for the raw signal, and another one that is put through a low pass filter, to smooth out the signal. The number of brekpoints (steps) can be controlled with a knob, or controlled through CV. Notice that changing the number of steps in the signal will affect the resulting frequency. This can be used to generate variation and random melodies by sending CV values to the input.

You can experiment with the values of the sliders to find interesting timbers, and adjust the parameters to sculpt the sound. It is a great option for generating drone sounds, and for adding a strong bass sound to your patches. It is not designed so much for melodies, but rather for slow changing textures with timbral variations.

Included in the Benard Mega Bundle Vol. 2.

-Poly CV Sliders This input allows you to control all the sliders with a single poly CV signal, such as the output of a Poly LF Noise. Set the polyphony to 16 to control all of the sliders with the poly signal. Otherwise only the sliders up to the polyphony value will be affected by the CV signal. You can also combine multiple poly signals for variation. Try adding a Poly LFO (with offset phases) in addition to the Poly LF Noise signal.

-Animate Sliders - When this toggle is engaged and a poly signal is connected to the Poly CV in, the sliders will move to reflect the values of the breakpoints as set by the poly signal. When there is no poly signal connected, this toggle will be dimmed.

-Frequency CV - This input allows you to modulate the frequency with a CV signal. For keyboard control set the attenuator to its maximum value. You can also use an audio signal for FM sounds to produce timbral variation.

-Filter Cutoff - This knob controls the cutoff frequency of the low pass filter. This only affects the filtered signal coming out of the Flrt Out jack, so if you're listening to the signal out of the bottom output, this knob will have no effect.

-Cutoff CV - This input allows you to modulate the cutoff value of the filter with a CV signal.

-Sub Osc - This knob controls the level of the suboctave oscillator.

-Reset - This button will reset all the sliders to their center position. It will only have an effect on the sliders that are not being controlled by the poly CV signal when one is connected.

-Randomize - This button will select random values for all the sliders. You can use it to quickly start the oscillators, as no sound will be produced when all the sliders are in the center position. The CV input below it allows you to randomize the values by sending a trigger signal. Randomization will only have an effect on the sliders that are not being controlled by the poly CV signal when one is connected.

-Steps - This knob allows you to select the number of breakpoint (determined by the slider values) that will be used to generate the waveform. Since the oscillator cycles through these values, reducing the steps will result in the frequency changing, as there are less values to step through. The sliders that are not active will be dimmed.

-Steps CV - This input allows you to control the number of steps with a CV signal. Notice that the dimming of the active steps will not change when there is CV control, and instead only the sliders up to the number set by the Steps knob will have normal transparency. However, the steps used to generate the waveform will still change with this signal. This is to avoid unnecessary fast changes to the visuals of the module that would be problematic especially when using audio signals.

-Fltr Out - This is the output of the signal after the low pass filter. The knob above it controls its level.

-Out - This is the output of the signal before the low pass filter. The knob above it controls its level.
