The Oberheim OB-X has a built-in Chorus, Stereo Delay, and Reverb effects. Each effect can be turned on or off via the red LED in the top left of each effect section. It’s also possible to lock any or all of the effects so that you retain your current effects settings even when changing patches. To activate the Lock, click on the padlock at the top-right of each effect, whereupon it’ll become ‘greyed out’.
The chorus depth is defined as the intensity of which the chorus modulates. Depth is specifically the range between the maximum and minimum values.
The chorus rate denotes the speed at which these shifts occur from maximum to minimum (i.e. Chorus Depth).
The chorus mode switch is related to how pronounced and prominent the modulation is. Higher mode (intensity) settings create a more noticeable and "bigger" chorus effect, while lower intensity settings produce a subtler, more transparent effect.
Chorus Amount sets the balance between the dry signal (containing no chorus) and the wet signal (containing only the chorus signal).
Sets the delay time of the left and right channels individually. In Sync mode, the delay times are from 1/32nd of a bar to 1 bar. In unsynchronised mode, the delay times are 125 to 4000 Milliseconds (4 Seconds).
This icon activates the Cross-feedback mode.
When illuminated, this feeds the left delay signal into the right signal and vice versa to create a ping-pong delay signal.
This icon activates the Link mode.
When illuminated, if you change the left Delay Time value, the right time will also change to the same value, and vice-versa.
