LFO KEYBOARD TRACKING AMOUNT

To specify how much the LFO rate tracks the keyboard
pitch, enter Shift mode and press the

BANK 2 and

PATCH 4 buttons. Pressing the low C key sets keyboard
tracking to zero, meaning key pitch will have no effect
on LFO rate. Pressing higher keys sets a proportionally
greater amount of keyboard tracking; the middle C on
the keyboard sets 1:1 LFO pitch tracking, meaning the
LFO rate will double when the key pitch doubles. The
high C key sets 2:1 LFO pitch tracking, meaning that the
LFO rate will change by four times for every octave of
pitch change.

LFO MIDI SYNC

This function lets you synchronize the Sub Phatty’s LFO
with an external MIDI clock signal, typically from another
synth, a sequencer, or a digital audio workstation. When
synced, the LFO rate locks to tempo, oscillating in
rhythm with its clock source. The

LFO RATE knob lets

you select the note division—whether the LFO cycles
once every eighth note, half note, or whatever. LFO MIDI
sync is turned on by default.

Engage Shift mode and press the

BANK 2, PATCH 3,

and

PATCH 4 buttons. Press the low C# key to turn on

LFO MIDI sync, and press the C key to turn it off. At
the

LFO RATE knob’s fully counterclockwise position,

a single LFO cycle is 4 whole notes long (384 MIDI
clocks). At its fully clockwise position, one cycle equals
a 1/64th-note triplet (1 MIDI clock). Please refer to the
chart on page 38 for a list of clock divisions available
for LFO sync.

NOTE: When no clock is present, the LFO will run freely
at a rate determined by its RATE setting.

FILTER ENVELOPE TRIGGER MODE

As mentioned in the Envelopes Overview, by default,
playing legato on the Sub Phatty prevents envelopes
from retriggering on subsequent notes; this is called
single triggering. You can change this behavior by
turning off single triggering in Shift mode. With single
triggering turned off, a new gate occurs each time you
play a note on the keyboard, regardless of whether
you’ve released the previous key; this is called multiple
triggering. You can select single or multiple triggering
separately for the amplifier and filter envelopes..

To specify single or multiple triggering for the filter
envelope, engage Shift mode and press the

BANK 3

and

PATCH 1 buttons. Press the low C key to turn select

single triggering, and press the low C# key to select
multiple triggering.
