Hi David,
First I grabbed a BandPassFilter from the prototype Menue.
Then a Mixer from the prototypes.
Replaced the SampleCloud before the mixer with the BandPassFilter prototype (by copy/paste).
When clicking the Mixer, you see under description the fist BandPassFilter as input.
Take the prototype BandPassFilter and place this next to the first one in the Mixer input.
Now you have 2 BPF's. Continue to your needs.
After doing this 3 times I copied the Noise(White) input and pasted this one on the other Noise(White) inputs. Making them to dissapear till one Noise(White) has left as input for the 3 BPF's. After this I added "_A", "_B" and "_C" to the VCS targets.
