Introduction

PMS-20 is an analog-modelled dual high-pass/low-pass filter. Simulating the characteristic Korg-35 filters from the iconic Korg MS-20 mono synth, PMS-20 brings the aggressive, screaming sound of the original unit to the Reason Rack.

Front Panel

1: High-pass Filter Section

CV Mod

CV MOD controls the amount of cutoff modulation from the CV input on the back.

Cutoff

Filter cutoff ranging from 20 hz to 20.000 hz

Peak

Filter resonance. When peak value gets high enough the filter will go into self-oscillation and produce a sine wave.

2: Low-pass Filter Section

CV Mod

CV MOD controls the amount of cutoff modulation from the CV input on the back.

Cutoff

Filter cutoff ranging from 20 hz to 20.000 hz

Peak

Filter resonance. When peak value gets high enough the filter will go into self-oscillation and produce a sine wave.

3: Amp Section

Input

Controls the level going into the filter. Higher levels results in the filter being saturation.

Output

Controls the output level of the filter. When the AUTO switch is on the level is controlled automatically.

O/L Lamp

Overload lamp indicates when the filter is saturating the signal.

Rage

The rage switch adds 20dB of gain to the input for extra saturation.

Auto

When adding input gain, the output level is controlled automatically, when the auto switch is engaged.

Mix

Mixes the DRY (unfitered) signal with the WET (filteret) signal.

Back Panel

Audio Inputs

Audio In

Stereo audio inputs. For mono signals use only the left channel.

Audio Out

Stereo audio outputs

CV Inputs

CV-In HP

Modulates the cutoff frequency of the highpass filter.

CV-In LP

Modulates the cutoff frequency of the lowpass filter.

Model

The model switch switches between the original PMS-20 filter model (A) and the new filter model (B) added in V.2.0.
