MOTM

OK - hope I can explain this clearly.

I have 2 MOTM 440 LPF's for stereo filter mangling.

I have a stereo synth pad going from Pro Tools to the 440's thus:

Left signal > 440 #1
Right signal > 440 #2

I have a slowish Tri LFO from MOTM 320 feeding CV In 1 of both
440's via a multiple. 440 #1 CV IN 1 knob set to slight negative, 440 
#2 CV IN 1 knob set to slight positive. This is for nice subtle 
stereo panning.

OK so far. Then I wanted to manually sweep the freq's of both filters 
simultaneously... so using 2 banana to 1/4 jack adapters on my Serge, 
I patch the Serge Processor into CV IN 2 of both 440's. 

Using the -/+5v knob of the Serge Processor I can attenuate both 
440's simultaneously right?

Yes - BUT this is working differently on each 440! I can only get it 
to work on both filters by setting 440 #1 CV IN 2 knob to fully 
clockwise BUT 440 #2 only works the same if I set its CV IN 2 knob 
fully counter-clockwise!!

Which filter is behaving correctly??
