Agreed, the retriggering is extremely poor when not in envelope mode. Retriggering is often a poor spot with a lot of filters.
It's too bad about the Squeezer, it has a LOT more potential if they'd just tweak the device more.
Note that a lot of software filters also have poor triggering from fast audio signals. Having the filter built into a soft synth isn't the same thing is triggering a separate filter plugin from an audio source.
