Hi All,

is there a way to target the LPF with expression pedal? or some other additional mod sources?

now im thinking about it, is it because that would mess with the other ‘hard wired’ sources, like ENV1 / 1 & LFO 2?

best  
Pete

Totally possible via the mod matrix. There’s a dedicated expression source button.

As @Quatschmacher indicates, use the _Ped/CV_ button in a direct modulation i.e.

1. Click Mod Assign
2. Hold down the _Ped/CV_ button
3. Whilst holding down Ped/CV button, toggle the _VCF: Freq_ slider
4. Use _Mod Amount_ dial to set the depth

Heh, my apologies Pete - I mistakenly thought I was on a _Super 6_ topic!! But the principle should be the same using the _VCF: LPF_ slider on the Super Gemini!

Hi ekeu - ok i must be doing something wrong - i will try again -

I did think the progress was the same as the hard wired panel destinations, but im not getting the MOD amount show up (or any effect if i chose LPF -

but its good to know if should be possible - ill have another go later today - i must be missing a step.

best  
Pete

In direct assignment, when you hold down the _Mod Assign: Source_ button and toggle the _LPF_ slider, you should see a cascade of lights move through the modulation section buttons from the right to the left, stopping at the light on the source button you’re holding. This indicates that the source and the destination slider have been paired. You can then adjust the _Mod Amount_ dial.

It’s an easy mistake to make at first.
