Example below works well if you want low-end emphasis on attack and a bandpass-like release.

Setup:  
env1: inverted, long release  
env2: long release  
vcf hpf: trk  
vcf drive = off or 2  
vcf keytrack = on  
vcf cutoff: low-medium, velocity modulation  
vcf resonance: medium-high  
vcf env amount: high  
vcf env source: env1 + env2  
dds2: slightly detuned
