PORTAMENTO / GLIDE
This section assigns glide, portamento, and glissando functionality to one or both oscillators.
OSC 1/2
Selects the oscillator(s) that will be affected by Glide, Portamento, or Glissando.
You can select OFF, Oscillator 1, Oscillator 2, or both 1 and 2.
GLIDE
Selects the Glide effect. When enabled, each note starts the pitch higher or lower,
smoothly reaching the actual note pitch. The position and speed of the glide is
controlled by Speed and Glide Amount knobs.
PORT
(left LED)
Selects the Portamento effect. When enabled, the oscillator pitch moves smoothly
from note to note.
GLISS
(right LED)
Selects the Glissando effect. When enabled, the oscillator pitch moves from note
to note in discrete semitone steps.
SPEED
Controls the rate for the Glide, Portamento, or Glissando effect.
NOTE:
In Performance Legato mode (Mono mode), this controls the slowest rate
when notes are played with minimum velocity in legato. When played with
maximum velocity, the speed is instantaneous.
GLIDE AMOUNT
Selects the interval where the pitch starts the glide from. The range is -32 to +31
semitones. Turning the knob counterclockwise starts the glide from below the
note, clockwise starts from above. If the knob is set to center (0) there is no glide
effect as the note starts with the actual pitch. This knob has no effect on
Portamento or Glissando, which start the pitch from the last played note.
CHORUS EFFECTS
The Xerxes synthesizer has a stereo analog Bucket Brigade Device (BBD) chorus circuit built-in with 3
different fixed chorus settings. When enabled, this effect is added to the sound before the final output.
A single button controls all 3 settings, plus an OFF setting when both LEDs are off. The stereo effect is
accomplished with 3 analog BBD delay lines, with two lines routed independently to L and R channels.
