there are necessarily several ways to patch this … but I would have said

VCO out - VCF in - VCF out - VCA in  
and ADSR out to the VCF CV and VCA CV (both where only the VCA, if you have no multiple)

and with this patch you will also necessarily need something that triggers your ADSR (square signal, LFO, clock …)

you can watch this thread for patching :
