basic synth programming question

i just getting into synths now, just curious bout something, say im modulating my filter cutoff with an lfo, what exactly is this doing?

like i know i can hear the wah wah and all that, but how exactly does it relate to the main cutoff freq for the osc.. , is it affecting the cutoff near the value that the main switch is set at and just going up and down from there?

because when i change the main value the freq changes alot, but then i can also mimick this sound by just using the lfo. the way im seeing it right now, is that the main cutoff i have set for my osc is like where the freq modulation starts from, and the lfo goes and does it from there but i dunno

ive played around for quite a while but cant exactly put my finger on how its working

if i set it to a negative value, (knob left) or positive value (right), whats the difference?

sorry if this question is vague too, i know eveyr synth is diff but im sure this would crossover to most synths. also, the one i been playin round on is vanguard and the filter is low pass (if it helps with any examples) thanxxx

most LFO's are bipolar (they go up+ and down-) some can be used as one shot envelopes, if you use positive settings the cycle will start with a positive value, if you use negative settings it will start going with a neg value, it's more useful when using slower LFO speeds or you want to use your LFO's for autopanning or something like that
