This control determines the initial cut-off frequency of the filter. The filter is a two-pole, low-pass type.
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.
This control determines the amount of filter envelope that modulates the filter. The control works independently from and in addition to the amount of LFO modulation from the Modulation section.
The default view of the mixer panel is the “Fine Control View” where the 2nd row of functions is knob based for complete control. Below is an explanation of the knobs found in the Fine Control View.
<aside> ⚙️ It is possible to change it to “Classic View” in the Settings Window for the set switches approach found in the hardware.

This knob controls the level of Oscillator 1 that is input into the filter. The level can be adjusted to the desired fine level from -INF dB (off) to +0dB (unity level) by increment of 0.01 dB.
This knob controls the level of Oscillator 2 that is input into the filter. The level can be adjusted to the desired fine level from -INF dB (off) to +0dB (unity level) by increment of 0.01 dB.
This knob controls the noise level that is input into the filter. The level can be adjusted to the desired fine level from -INF dB (off) to +0dB (unity level) by increment of 0.01 dB.
This knob determines the amount of Filter Tracking going into each voice. It can be adjusted to the desired discrete filter tracking value from 0% to 100%. When set to “100%”, it causes the filter in each voice to “track” the keyboard.
<aside> ⚙️ It is possible to set Oberheim OB-X’s filter section to “classic” mode in the Settings Window. In this view switches control Osc1 level, Osc2 level, Noise level and Tracking as in the original hardware instrument.
