Attack
Operation Manual 14 Waldorf
Oscillator Section
The Attack is equipped with two oscillators that have almost
identical functionality. Oscillator 1 additionally contains an
integrated FM (frequency modulation) section. The following
explanation is valid for both oscillators.
Pitch 0.007984...<20000 Hz
Sets the pitch of the oscillator over a very wide range. This is necessary to reproduce
drum and percussion sounds.
Semitone C-11...E 10
This parameter works with Pitch, setting the pitch of the oscillator in semitone steps.
This is useful for melodic sounds. Lead and Solo sounds sound interesting when you set
one oscillator to e.g. a fourth (+5 semitones).
Detune -50...+50
This parameter also works with Pitch, fine-tuning the oscillator in cents. The audible
result of detuned oscillators is a chorus or flanger effect. Use a positive setting for one
oscillator and an equivalent negative setting for another.
Shape (Waveform) Tri, Sine, Pulse, Saw, S&H, Noise, Sample 1-3
Sets the type of waveform to be generated by the oscillator. The parameter is called
Shape instead of “waveform”, because it doesn’t necessarily set only classic synthesi-
zer waveforms, but it also generates noise, sample&hold and three samples. However,
the term “waveform” is used interchangeably throughout this manual. The following
shapes are currently available:
Triangle selects the triangular waveform. The triangle mainly consists of odd
harmonics with very low magnitudes. It is perfect for nearly all drum and percussion
sounds.
The Sine waveform consists of the fundamental frequency only. It has no
harmonics at all. With a sine wave you can create clean bass drums and snares. The
sine wave is also perfect for FM.
Pulse selects the pulse waveform. This waveform
produces a hollow / metallic sound and is perfect for bass drums and snare drums.
Saw selects the sawtooth waveform. A sawtooth wave has all the harmonics of
the fundamental frequency in descending magnitude. This waveform is pleasing to
the ear. You can use it for bass and lead sounds.
S&H (Sample&Hold): S&H samples a random value and holds it. Pitch selects
the time of this process. S&H is perfect for industrial-type FX sounds and as an FM
source.
