I'm trying to invert the polarity of an LFO. ie when the LFO is at its peak, the inverter outputs the trough, and so on... I have tried the inverter set either to standard, or inverse bipolar, but it outputs the same signal (same polarity) either way. Any ideas?

I hope I manage to get my intention across here via text. I have included an example, as you will see, I've used the left channel for one oscillator (non inverted LFO) and right channel for the inverted LFO.

Any help would be much appreciated Smile

The symmetry of the wave modulation is confusing the issue. The pulse wave sounds the same no matter if it is made thinner or fatter. If you move both sets of wave shape and mod amount to the middle position, you should hear the effect you are after.

It's not being very friendly with me, as you can hear for yourself!

To illustrate what I said. Also added two modules so you can see the inverter working. Very Happy
