Modulation is a vital facet of synthesizer performance and sound design.
In short, whenever one signal is used to change the value of another– it
is known as modulation. Modulation can come from a number of sources–
the Envelope Generators, Keyboard Tracking, an audio Oscillator (FM),
or a dedicated Modulation oscillator such as the one found here. Based
upon an analog oscillator that operates in the low-frequency range
(Low Frequency Oscillator or LFO), the Modulation module can apply
modulation to multiple destinations at once, and in varying amounts.
In addition to the hardwired modulation routings that can be addressed
using the panel controls, Noise and S/H (Sample and Hold) are available
as patchable modulation sources, as is the signal specified by the
WAVEFORM and RATE knob settings.
NOTE: A second, simple LFO can be found in the Utilities 2 module.
NOTE: The PITCH AMT, CUTOFF AMT, and PULSE WIDTH AMT knobs are
used to specify the maximum amount of modulation to be applied to specific
parameters. In order to actually apply the modulation and hear the eect,
the MOD wheel must be raised from its minimum position.
RATE
The Rate, or speed, of the Modulation oscillator can be set from .07 Hz to
1.3 kHz using the RATE knob. The LED indicator below this knob will flash
at the current Rate setting.
TIP: Hold the SHIFT button while adjusting the Modulation RATE knob to fine-tune
the Modulation rate.
WAVEFORM
This six-position knob is used to select the Waveform for the Modulation
oscillator. The choices are Sine, Sawtooth, Ramp, Square, Staircase, and
Smooth Random.
NOTE: The Staircase waveform is a stepped Triangle wave. While the Triangle wave
itself is determined by the Modulation RATE knob, the stepped values are sampled
and held with each rising pulse of the ARP / SEQ clock, as determined by the
ARP / SEQ RATE knob.
PITCH AMT (Amount)
Applying modulation to the pitch of an oscillator can create anything from
a gentle vibrato to a vast cascade of notes. The PITCH AMT knob determines
the maximum amount of modulation that will be applied to the Pitch of the
selected oscillators when the MOD wheel is at its maximum position.
