Vibrato is an independent LFO that’s directly linked to the Modulation Wheel on your external controller keyboard. This knob affects the speed of global vibrato.
This knob affects the depth or amount of vibrato and can be assigned via a CC to your external controller keyboard. It can be used to apply a subtle amount of global vibrato as an integral part of a Patch.
<aside> ⚠️ When being controlled by an external controller or Modulation Wheel the Vibrato Amount Knob does not animate.

This determines the cutoff frequency of the filter. This knob effectively controls the positions of OB-E’s 8 filters, each of which can be in a different mode (Low pass, high pass, band pass or notch) and at different starting values in the patch. So the effect may not always as complete as you may expect from a conventional filter frequency knob.
This control determines the amount of resonance (”Q” or “emphasis”) of the filter. Note that the filter will not self-oscillate even in its maximum position.
The Modulation Knob is a reversible attenuator that applies an amount of envelope modulation to the filter.
In its vertical position no modulation is applied. As the knob is rotated to the right the selected control signal modulates the VCF. As the knob is rotated to the left, the selected source modulates the VCF inversely driving the VCF frequency down instead of up.
OB-EZ has two envelopes. The Amp envelope controls the loudness of the synthesizer over time, and the Filter envelope controls the Filter Frequency over time in accordance to the VCF Mod knob.
Use the Amp and Filter buttons to choose which envelope is currently displayed on the Envelope controls
