CUTOFF (CUTOFF FREQUENCY KNOB)
The Cutoff knob specifies the frequency where the Filter is applied. Turning
the knob to the right will open the filter, allowing more harmonic content to be
heard, creating a brighter sound. Turning the knob to the left will close the filter,
causing more harmonic content to be filtered, creating a darker sound.
RES (RESONANCE KNOB)
Directing the output of the filter back to the input allows the Moog filter to
create a harmonic boost at the cutoff frequency. The amount of this boost, or
emphasis, is controlled by the Resonance knob. By increasing the Resonance
and decreasing the cutoff, the Werkstatt filter can be made to self-oscillate,
creating a sine wave that can be used as second audio sound source.
MODE (MODE SWITCH)
The VCA can function in one of two ways, controlled by the Mode switch.
ON: In this position, the VCA is always on, and the audio signal of the
Werkstatt is output continuously, all the time. This setting is great for when
you are creating synthesizer sounds and effects that need to play for an
extended period, or droning sounds.
EG: EG is short for Envelope Generator. When the switch is in this position,
the VCA is controlled by the Attack, Sustain, and Decay characteristics of
the Envelope Generator Module.
The Werkstatt uses the classic 24dB per
octave Moog Ladder filter. This low-pass
Voltage Controlled Filter (VCF) selectively
shapes the timbre of the sound created
by the oscillator, by attenuating and/or
emphasizing certain harmonic elements.
This section controls the output level of the
Werkstatt. As you may have noticed, there is
no Volume knob on the Werkstatt. The VCA
boosts the final audio signal to a suitable level.
