Mmm..no, the decay for that drop sound is relatively slow, definitely not fast, otherwise itll sound more like a kickdrum sound. The sustain could well be low, it should certainly be lower than the decay, in fact it could be 0 without a problem if you only want the pitch drop.
Sorry if phrased confusingly, but yes, I did mean, use the filter envelope to control the pitch of the oscillator.
