[nay-seven]

sadly no parameters visible but you can use a preset manger to recall presets and also midi learn possibilities..



what they said :
Engineers Filter is a filter plugin that allows for extremely steep filtering. It achieves this by implementing high order IIR filter design methods that are commonly used in science and engineering, namely Butterworth, Chebychev, inverse Chebychev and elliptic (aka Cauer) filters. Each of these filter design methods can be applied to create lowpass, highpass, bandpass, bandreject, high/low shelving and peak/dip filters of orders up to 20.
