Sound Parameter
Overview of Functions
The Waldorf Blofeld consists of numerous sound-shaping
components. The following pages describe all parameters
in detail. Additional information can be found in the
chapter „Sound Synthesis Basics“ on page 78.
You should know that the Blofeld consists of two different
types of components for sound generation and sound
shaping:
• Sound synthesis: Oscillators, Ring Modulator, Noise
Generator, Filters, Amplifier, Effects. These modules
represent the audio signal flow. Sound generation
actually occurs within the Oscillators. They produce
square, sawtooth, triangular, sine and wavetables.
Noise can also be added to the mix. The Filter then
shapes the sound by amplifying (boosting) or
attenuating (dampening) certain frequencies. The
Amplifier and the Effects are located at the end of the
signal chain. They determine the overall volume of the
signal and add some effects like chorus, flanger, delay
etc.
• Modulators: LFOs, Envelopes, Modifiers, Modulation
Matrix.
These modules are called Modulators. The Modulators
are designed to manipulate or modulate the sound
generating components to add dynamics to sounds.
The Low-frequency Oscillators (LFO) are designed for
periodic or recurring modulations while Envelopes are
normally used for modulations that occur once on
each note. These generators are assigned to
parameters through the Modulation Matrix and
influence these parameters to alter a sound. In
addition, the Modifier unit can process various
mathematical operations and functions on the
modulation signals.
Oscillator Section
The Blofeld offers three oscillators that nearly use the
same parameters for editing.

A detailled introduction of the oscillators can be
found in the chapter „Sound Synthesis Basics“.
The most important controls of the oscillators can be
found in the Oscillators parameter matrix.
