The Included VST Instruments
Prologue
• If Osc 1 and 2 are tuned to the same frequency, and no modulation is applied to
the Osc 2 pitch, nothing much happens.
However, if you change the pitch of Osc 2, drastic changes in timbre can be
heard. If the oscillators are tuned to a harmonic interval such as a fifth or octave,
the ring modulated output sounds harmonic, other intervals produce inharmonious,
complex timbres.
• Deactivate Oscillator Sync when using ring modulation.
Noise Generator
A noise generator generates noise (all frequencies at equal levels). Applications
include simulating drum sounds and breath sounds for wind instruments.
• To hear only the sound of the noise generator, turn down the output level for the
oscillators, and turn up the Noise parameter.
• The noise generator level is routed to Envelope 1 by default.
See “Envelope Page” on page 195 for a description of the Envelope generators.
Filter Section
The circle in the middle contains the filter parameters. The central control sets the
filter cutoff parameter and the outer ring the filter type:
Parameter Description
Filter type Sets the filter type to either low-pass, high-pass, band-pass or notch,
see
“About the Filter Types” on page 192.
Cutoff This knob controls the filter frequency or cutoff. If a low-pass filter is
used, it could be said to control the opening and closing of the filter,
producing the classic sweeping synthesizer sound. How this
parameter operates is governed by the filter type mode.
Emphasis This is the resonance control for the filter. For low-pass and high-
pass filters, raising the Emphasis value emphasizes the frequencies
around the set cutoff frequency. This produces a generally thinner
sound, but with a sharper, more pronounced cutoff sweep. The
higher the filter Emphasis value, the more resonant the sound
becomes until it starts to ring (self-oscillate), generating a distinct
pitch. For band-pass or notch filters, the Emphasis setting adjusts the
width of the band. When you raise the value, the band where
frequencies are let through (band-pass), or cut (notch) becomes
narrower.
Drive This can be used to adjust the filter input level. Levels above 0 dB
gradually introduce a soft distortion of the input signal, and a
decrease of the filter resonance.
