Converting a bipolar LFO into a polar one?
Hello. Im currently trying to do exactly what the title says.
Im using the lfo macro from the library but it spits -1 to 1 values. And that is not good for me.
I tried to fix this using math but i just couldn't find a way to achieve the result.
Do you guys know a way to achieve my goal? thank you in advance.

Sure. If you want the LFO output to range from 0 to +1, multiply by 0.5 and then add 0.5.
If you want the LFO output to range from 0 to -1, multiply by 0.5 and then subtract 0.5.

Or use the rectifier module 0 .. 1 plus invert 0 .. -1
With a Crossfade between both you get a simple double LFO

Yes... but the problem is that by doing this. (which i tried before) you always have a persistent .5 output which is inconvenient for things such as pitch because it messes with your tuning.

If you have a multiply after the unipolar lfo then it shouldn't be a problem.
In the image below, Blue is Pre-Depth control and Red is Post-Depth. The only time you'd be stuck with a 0.5 constant is if you control the amplitude of the LFO Pre-Bi/Uni conversion.

Jonathan has the answer: put the depth controller at the end of everything.
