Cobalt 4+
Pitch
Tune
+/- 48. This sets the coarse tuning of the oscillator over an eight-octave range, in
half-steps.
Fine
+/- 100. This sets the fine tuning of the oscillator, in cents (1/100 of a semitone).
Slope
+/- 2.00. The Pitch Slope allows you to adjust the way in which the oscillator's
pitch changes as you play higher or lower on your MIDI controller. The slope is
centered around middle C (C4).
+1.00 is the default setting; pitch will track the keyboard normally.
Values above +1.00 increasingly stretch the oscillator tuning. In other words, above
C4 the oscillator gets increasingly sharp, and below C4 the oscillator gets
increasingly flat.
+2.00 means the pitch changes two octaves over only a single octave of MIDI input.
+0.50 means that an octave of pitch is spread out over two octaves of MIDI input,
producing a quarter-tone scale.
0.00 makes all notes play at middle C (C4).
A negative Slope value inverts the pitch tracking, so that as you play higher on
your controller the pitch gets lower, and vice versa. Normally you would use this
adjustment on oscillators that contribute harmonics within a patch, rather than on
ones responsible for fundamental pitch.
NOTE: Pitch slope also changes the way that Multisamples are mapped across the
keyboard. When you are editing a Multisample in the Multisample Edit window,
it's generally best to make sure that Pitch Slope is set to 1.00.
4 Pole Filter
Filter
Cutoff
0-100. This controls the cutoff frequency of the 24dB per octave lowpass filter.
Frequencies above the cutoff are cut, and frequencies below the cutoff are passed
through unchanged.
Generally speaking, the lower the cutoff, the darker the sound; the higher the
cutoff, the brighter the sound.
Note that the Envelope and Key Track parameters also affect the cutoff frequency.
