I saw a similar issue and was confused until I wrote this post and finally realized what is happening. So the voltages seen by my Mordax weren't matching what I saw in the NerdSeq automator visualizer. I set up LFO automators to output to CV for tracks 1 and 4 with the same parameters. The track 1 LFO worked fine: I see a nice sine wave swinging from -5V to +5V (the green line on the Mordax). But for some reason, track 4 showed only the top half of the sine wave ranging from -5V to 0V. The white dot that shows the current value on the NerdSeq automators screen looks correct -- it swings all the way left and right -- but the voltage coming out didn't match that.
I understand the automator's CV output is added to any other CV output, but since the sequencer was off I assumed there was no other CV being output to the track. But it seems there is ALWAYS CV coming from the tracks, even when the sequencer is off. I created a brand new project, went straight to the automator, and set up an LFO on track 1. It was only showing me the top half of the sine at values of -5V to 0V! Then I created a pattern on track 1 and used the FX set CV. If I set the value to 800, turn on the sequencer so the FX take effect, and then turn off the sequencer, I see the full waveform. I believe this is because 800 is 0V. I'm guessing the default CV value for a track with no patterns is 0, ie: -5V. This would explain what I saw: when -5V from the (nonexistent) pattern is added to the LFO (-5v to +5V), we get -10V to 0V which becomes -5 to 0 when the CVs are added in a bipolar fashion.
