This pack is a set of resonant filters for the MOD FX section of the Prologue, NTS-1, and Minilogue XD.

There are four second order (12dB/octave) filters – low pass, high pass, band pass and band reject, plus a 24dB per octave ‘classic’ low pass.

The latest addition to the Filter Pack is a 24dB (4th order) Low Pass Filter with soft-clipped resonance. This filter has that smooth, but aggressive sound of a classic low pass filter. As with the other MOD FX filters, there is no key-tracking or MIDI triggered envelope, but of course, the cut-off frequency can be assigned to a number of sources including mod wheel or CC controller.

Each filter has the same controls:

Control1 (Speed) sets the frequency of the filter, and can also be modulated with the Mod wheel.

Control 2 (Depth) controls the amount of resonance of the filter.
