Tuning
There are many parameters that affect tuning in Viking. Tuning is a very important factor in
achieving an analog sound.
Fine Tune
Fine Tune adjusts the overall tuning, including all three oscillators.
Generally, it would be used to transpose the instrument or adjust the
pitch of the oscillators simultaneously. It is the only way to adjust the
pitch of Oscillator 1.
Glide
Glide Rate, also known as portomento, adjusts how quickly the
oscillator pitch changes to a new note. Turning the Glide Rate up
makes the pitch transition smooth between notes.
Oscillator Frequency
Both Oscillators 2 and 3 have a frequency control for adjusting their
pitch with respect to Oscillator 1. Detuning notes by semitones can
create chords. Fine adjustments of these knobs can widen or fatten
the sound of a patch.
KB Stretch
Keyboard Stretch adjusts the tuning of the
keyboard notes. Normally, each key is one
semitone apart. Analog keyboards often go out
of tune, and the keyboard spacing is no longer
one semitone. The note spacing can be adjusted
from 0.98 semitones to 1.02 semitones. C5 is at
the center while the rest of the notes become
detuned. If you don’t want C5 to be in tune you
can adjust the Fine Tune or the oscillator
frequency controls.
Drift
Drift simulates the instability oscillators have
in their frequency. Even when the tuning trim
pots have been set very accurately the
oscillator frequency of an analog oscillator
drifts slightly up and down at a slow rate,
causing it to be slightly out of tune. Turning
this control down will fix the frequency at an
exact rate. Turning it up magnifies the effect.
