Scaling & DC Offsetting Bipolar to Unipolar

Transform a bipolar signal into a unipolar one while tailoring its range with IOU. Here's how

to modify a bipolar VCO signal into LFO rates suitable for modules requiring unipolar

modulation:

Connect your VCO/LFO's bipolar output to IOU's input. Set the Pre / Post switch to 'Post' to

add the DC offset after scaling. Adjust the DC Offset Slider to set the base voltage level,

effectively shifting the zero point up to the desired starting voltage for unipolarity. Use the

Scale knob to scale down the peak-to-peak voltage to fit within the module's range, turning

it until the output matches the required amplitude.

Note: This scaling and offsetting technique is also ideal for processing audio signals with a

wavefolder lacking a symmetry control. By adjusting the DC Offset on the IOU, you can

effectively alter the symmetry of the wavefolding effect, granting you an additional

dimension of sonic sculpting. 2x Gain can be useful if extra wavefolding is required.
