The AutoFilter is a Plug-In Filter for Logic which can remove or reduce thinning of the throughput when using resonance.

Extended information

"The 6-, 12-, 18- or 24 dB AutoFilter can not only trigger a complete ADSR and a richly equipped LFO with speed modulation on the input level, with its freely controllable fatness parameter it can also be used as an effective weapon against the often experienced ""thinning"" of the throughput when using resonance. In other words: it doesn't get any more fat than this. For the friends of aggressive sounds there are individually controllable pre and post filter distortions available."
