FILTER SLOPE
By default, the Sub Phatty’s filter rolloff is set to the
classic Moog 24dB-per-octave slope. You can change
this setting in real time as you play, making the change
in slope part of your performance.
To change the filter slope, engage Shift mode and
press the BANK 2 and PATCH 1 buttons. Use the four
lowest notes on the keyboard to select the slope.
Pressing the C key selects a 1-pole, 6dB-per-octave
slope. C# selects a 2-pole, 12dB-per-octave slope. The
D key selects a 3-pole, 18dB-per-octave slope, and D#
selects the default 4-pole, 24dB-per-octave slope. After
you’ve made your selection, press ACTIVATE PANEL to
disengage Shift mode.
WAVEFORM MODULATION DESTINATION
To change how waveform modulation is routed, enter
Shift mode and press the BANK 2 and PATCH 2 buttons.
Then use the three lowest keys to specify whether
waveform modulation will be applied to oscillator 1
(press the C key), oscillator 2 (press the C# key), or both
oscillators (press the D key). Note that the WAVE AMT
knob must be turned up for waveform modulation to
have an effect.
LFO RANGE SELECTION
The Sub Phatty’s LFO has three selectable ranges:
0.01 to 10Hz, 0.1 to 100Hz, and 1 to 1000 Hz. Although
the mixer has no audio input for the LFO, an audio-
frequency oscillator can be very useful as a modulation
source, allowing the Sub Phatty to produce classic,
clangerous FM (frequency modulation) tones.
In Shift mode, press the BANK 2 and PATCH 3 buttons
to change the LFO’s range. Press the low C key to
assign the LFO to its lowest frequency range, from 0.01
to 10Hz. Press C# to assign the LFO to its middle range,
from 0.1 to 100Hz. Press the D key to assign the LFO to
its upper range, from 1 to 1,000Hz.
NOTE: No matter which range you choose, modulation
at normal vibrato rates (between 5 and 10 Hz) is possible.

MODULATION PARAMETERS
Shift mode also lets you determine several modulation parameters, including the waveform modulation
destination, LFO Range, LFO pitch tracking, and whether the LFO syncs to tempo.
