I've noticed what appears to me to be unexpected behaviour with [lores~] in Max 7.0.1 (on OSX 10.9.5).

- residual level in the stopband increases

- resonance around the cutoff frequency increases

This gets very extreme with high cutoff frequencies. Even with a resonance of 0 (or close to 0 such as 0.0001), a cutoff frequency of 10 kHz essentially results in a peak filter rather than an LPF. Two named images are attached, showing the output of [lores~] with white noise input.

I ask mainly because I've also tried a custom filter external that was created using the [lores~] example in the SDK as a starting point, and it exhibits a similar issue.

Lowres~ 'breaks' with high cutoff frequency
