OSCILLATOR MODULATION
Changes in Oscillator pitch can come from multiple sources, but two are immediately available without
patching: the Sequencer
PITCH 1-8
knobs and the VCO Envelope Generator, which is itself directly
affected by the Sequencer
VELOCITY 1-8
knobs.
SEQ PITCH MOD
This three-position switch determines which Oscillators are being controlled,
or modulated, by the Sequencer
PITCH 1-8
knobs.
VCO 1 & 2
The Sequencer
PITCH 1-8
knobs are assigned to the Frequency of Oscillator 1
and Oscillator 2. This is useful for creating sequenced bass and lead lines where
Oscillator 1 and Oscillator 2 are tuned in unison.
OFF
The Sequencer
PITCH 1-8
knobs are not assigned to either Oscillator, but can still be used in
conjunction with the
PITCH CV
output in the Patchbay. This selection is useful for creating droning
and non-pitched percussion sounds like high-hats.
TIP:
With the
SEQ PITCH MOD
switch set to
OFF
, try patching the
PITCH CV
output to different CV
inputs and experiment with using the Sequencer
PITCH 1-8
knobs as a sequenced modulation source.
(See preset Quick Hats on page 33.)
VCO 2
The Sequencer
PITCH 1-8
knobs are assigned to the Frequency of Oscillator 2 only. This is useful
when used with
FM
or
HARD SYNC
for adding synchronized motion to a static percussion sound.
VCO DECAY
Your DFAM is equipped with an Envelope Generator (EG) dedicated to
modulating the Pitch of its Oscillators. The Decay Time of this EG is set
using the
VCO DECAY
knob.
IMPORTANT NOTE:
If the
VCO EG AMOUNT
knobs are at center position, no
Pitch Modulation will occur and the
VCO DECAY
knob will appear to have no
function. This setting can be quite useful for creating sequenced bass lines.
7 O’CLOCK (MINIMUM)
The Decay is almost immediate and its effect on the Pitch of the Oscillators is extremely snappy.
This is good for adding a sharp impact to the initial attack of a sound.
9 - 10 O’CLOCK
This setting is useful for creating the punch that occurs when a drum head is hit with a drum stick
or beater. As this knob approaches the 10 O’clock mark, it will introduce more of an exaggerated or
rubbery sound to the attack of a note.
12 O’CLOCK AND BEYOND
These settings are useful when paired with slower sequences for creating exaggerated “booms” or
spacey sounds that decay slowly over time.
NOTE:
The Sequencer
VELOCITY 1-8
knobs are connected to the Velocity input of the Envelope
Generators, providing dynamic variations to both the Amplitude and Decay Time of the VCO
Envelope Generator.
