I wrote that out yesterday from memory of what to do and missed the filter mode, cutoff and resonance settings completely! But it sounds as though you are going well without them, although I will add that I followed my own instructions and set-up that patch with filter mode on band-pass, cutoff about 1/3 and resonance at about 3/4. Very very little env amount and came close, so cool. Maybe less resonance as it tends to accentuate the filter envelope and that will stop it from sounding like that piano-y type sound.
Try playing with the release times for the envelopes. Set them to be about the same, then play with the filter release. Notice it can create a clicking if it's a good deal shorter than the amp release? Move the slider away from zero until you are happy with the sound.
