Looks like you’ve got the cables the right way round, hmm, fault finder time !
Ring= Red = Right
So CVB goes to the Top for Pitch as you have it
I presume your insert cable is sound, so, is your A4 bust, the CV outs can go south (albeit in exceptional circumstances)
Try setting CVC for now to Value Lin
Make the Voltage range be e.g. -1v to 1v
Assign an LFO to that (dest value CVC), make it square and crank up depth
swap over that Insert cable in CVC/D outlet
and put the white cable on the Total Input
Have no other modulations set and bring up the T.Ext value on the LPF e.g., make sure to close the filter halfway first so you can hear the modulation effect
I guess i’m saying, check your A4 and cables by testing a simple ‘external’ LFO out, do the same for CVD and choose a different shape, swap the cables over (btw if white is not CVC switch the cables around in your second video, Ring Red for CVB)
If that’s all good or you know your A4 and cables are fine then … it ain’t track mute, but have you selected The source Track in the settings page to be CV track (looks good in 1st vid, check both are)
To keep it simple i’d disconnect the MIDI and USB for now as i’ve no idea how that’s all plumbed behind the scenes
Nothing else in MS either and you have a vanilla patch already
Puzzled a bit as to where to turn next, maybe don’t assume your insert cable is coloured correctly - is it definitely separating tip from ring - try in headphone out and set up an A4 sound with pan to test it isn’t just copying the signal
hook e.g. the ESP Trig Out (far right) to the Initial level VCA to ‘drone’ your MS whilst you try out lfo adjustments on A4
If cable is duff, use normal TS cables, just ground CVB and CVD and then use CVA and CVC
Reduce the variables for what might be wrong here, see how that goes, maybe check your patch points on the ms by cabling up to the inputs only on that … wheel to pitch, button to trig e.g.
