Reaktor building, bipolar/unipolar LFOs

Me.0

Hi there, i am trying to create a switch to make the LFO bipolar/unipolar. i have checked about this topic online but i could not find anything that helped, maybe because is very specific to my synth.

I'll show what is my situation:

I have this LFO sending with "IC send" in to a output matrix macro(Next)

the "IC receiver" receives LFO that goes into an output

i then have an input section of the matrix that is connected to the parameters i want to control,

And the LFO patch is added the parameter control.

To complete the connection, I have a Patch-bay that connects the lfo's output to the parameter' input. what i have is a unipolar LFO.

I than created a macro that allows me to switch from bipolar to unipolar but i have an issue.

I have 6 LFOs that can be patched at any parameter of my synth in this way; the issue now is that with this set up all the lfos become bipolar or unipolar when the switch is On/Off (because the bi/uni switch is at the end of the chain and also i now have to put a switch for each parameter.) I would like to have my 6 LFOs to be able to switch independently , so i have more control and possibilities. To do so, I have to place this macro at the start of the chain before the LFO signal is sent to the matrix (first picture). i tried (next pic).

but it won't work. could anyone help me out please?

Thank you!

To turn a bipolar LFO with a range of -1 to +1 into a positive unipolar LFO with a range of 0 to +1, add a multiply/add module after the LFO output. Put the LFO into the top pin, and 0.5 into the 2nd and 3rd pins. To turn it into a negative unipolar one, change the 2nd 0.5 to -0.5.

And, always feed the LFO's A input with a constant 1. Amplitude adjustments should be made after the multiply/add module.

This won't necessarily work on pulse waves, which sometimes adjust their output polarity based on the pulse width.

what do you mean by it won't work? it wont send the signal? or the signal it sends is not correct? or…?

hi all, sorry for not getting back, i have solved the issue, i had to simply change the values of the "IC send" and "IC reciver" from (max 1 / min 0) to (max 0.5 / min 0.5) and it worked.
