(notches), the middle one of which is at the so-called ‘mid-shift’ frequency. All

three of these filter types are widely used in contemporary music performance.

Each of them has its own distinct sound, a large part of which is directly related

to the shape of its frequency response graph. The first two types are embodied

in the moogerfooger MF-101 Lowpass Filter, while the six-stage phaser happens

to be one of the modes of your MF-103.

PHASER PARAMETERS

The following phaser parameters are under your control in the MF-103:

MODE: 6-STAGE or 12-STAGE, selectable by the right-hand rocker switch.

OUTPUT: AUDIO (main output), or AUX, each with its own output jack.

RESONANCE: Changes the height and sharpness of the frequency response

peaks. Use the RESONANCE panel control and/or the RESONANCE pedal control

jack.

SWEEP: Moves the frequency response pattern through a six-octave range. Use

the SWEEP panel control and/or the SWEEP pedal control jack.

We’ll now use frequency response graphs to show how each of these

parameters affects your MF-103 frequency response. We will always start with

the ‘basic’ panel setup, which is:

AMOUNT: 0 (minimum LFO modulation)

SWEEP: 5 (middle of the range)

RESONANCE: 0 (no resonance)

Right-hand Rocker Switch: 6-STAGE

Output Jack: AUDIO OUT

You may want to experiment with the panel controls and switches as we discuss

each of the parameters.

BASIC SETUP: Figure 5 shows the MF-103’s basic frequency response, the

response that you hear when the panel controls are set up as in the basic setup.

The mid-shift frequency is a little more than two octaves above middle C, and

there are about two-octave intervals between adjacent dips.
