I’ve yet to find much use for the lo setting on VCO 1 and 2. Any tips?
As a variable metronome ? Or simulating the sound of a leaking faucet water droplets (by passing thru the resonating filter) ? Or simulating the sound of a clock (using both 1 and 2 one octave appart) ? As subsonic frequency generator for testing woofer speaker (using triangle wave and a power amp) to check for damaged suspension or deformed voice coil ?
I’m sure there are still other uses that I didn’t think about… 
This is surely gonna change the way I make music! 
No, but seriously, I’m a bit surprised I haven’t found anything at all about this, googling the web. The VCO 1 and 2 LO settings seem quite esoteric for an instrument that otherwise only sports very basic (yet highly useful and flexible) settings.
i hardly use the lo setting
some way i always end up with hi setting aand freq modulating the vco’s and filter by it.
Multiple detuned VCOs in LO mode combined with noise make for explosive sound effects.
