The original minimoog owners manual describe the setting this way: "The LO position produces sub-audio clicks which may be used for rhythmic effect."
The rythmic effect is dependent on the chosen waveform and the tuning.
I think the LFO settings (LOs) in generel perhaps is at too low frequency. But i don't know. And i don't know if that's a part of the issue. But it is a low frequency setting.
The issue can also be a wavewidth issue or something else.
The setting should modulate sound, not just click.
It's correct it's a modulating click, but it should be possible for example to have repeating sounds, and bell-tree like effects and other sound effects depending on the Waveform, tuning, filter and ENV settings.
But MINI V just have noisy clicks no matter what you do. That's wrong.
The setting works on Monark that i have. Monark is to me harsh sounding though.
EDIT:
In this manual
https://www.moogmusic.com/sites/default/files/Minimoog_Model_D_Users_Manual_Web.pdf that's not the original Model D owners manual, the LO setting is described like this:
"The RANGE knob selects the fundamental octave
for each oscillator over a five octave range. A
sixth LO setting brings the pitch down even
further, allowing the Oscillator to be used for
other purposes, such as a modulation source."
