this is the module
this is the official description
"Random voltage generator
3 outputs, either clocked by the 3 outputs of the random gate generator, or by a common external clock.
Distribution control: SPREAD control, scanning between constant, bell-shaped, uniform or discrete distributions; and BIAS control biasing the generated voltage towards the bottom or top of the voltage range.
Adjustable range: 0 to +2V (for melodies), 0 to +5V, -5V to +5V."
and from the manual:
"J. Output voltage range. 0 to +2V, 0 to +5V or -5 to +5V."
and in real life, you have prerecorded scales, say a major scale, from which this sequencer chooses randomly notes creating random melodies you can lock anytime. You can also choose the number of steps (notes) from 1 - 16 per locked random sequence so the module can be locked in a 10 step/notes sequence for example. The three modes just choose in an ascending fashion the voltages (0 to +2 Volts or 0 to +5 Volts range - less problems with the General CV) or both ascending and descending voltages (+5/-5 Volts - where the General CV usually resets almost instantly).
