The 1026 Preset Voltage module is similar to a conventional dual eight-step sequencer, but instead of playing consecutively through its steps, it has buttons and CV inputs allowing random selection of any stage. It's useful for making slow changes, for example, changing the key center of another sequencer (such as the 1027 Clocked Sequential Control) but it can run at any speed, in any order depending upon the CV sources it's paired with.
