OCTAVE
sets this oscillator's base octave to 32', 16', 8' or 4'.
In setting "HI" and "LO" the oscillator doesn't respond to incoming pitch
information. The oscillator constantly oscillates with a fixed frequency.
GLIDE
sets the duration of the glide-effect. This defines the time period for the
pitch to travel from one note to the next played note. This function is
also referred to as portamento or slide. It is well suited for solo work.
With GLIDE set to zero, there will be no pitch-transitional-effect.
The glide-effect can also work automatically. This AUTO-function can be
enabled/disabled using EDIT PARAMETER 5. With AUTO GLIDE enabled,
the glide-effect will only be active with notes played legato, meaning a
second note is played while the first note is still held. When not playing
legato, the glide-effect will be inactive with AUTO GLIDE activated. To
activate the PerFourMer MKII's legato-function see chapter "Envelope
Generator" (See page 20).
EG INT
This control sets the modulation amount of the envelope generator
towards the oscillator's pitch. Modulation can be applied positive or
negative. In its center-position, modulation is turned off. This control
offers a center-catch.
TUNE
this control tunes the oscillator continuously within a range of approx.
±7 semitones.
LFO INT
sets the modulation intensity for the LFO targeting the pitch or the pulse
width of the oscillator. In its center position, the modulation is turned
off. This control offers no center catch to allow for sensitively adjusted
vibrato-effects.
Turning LFO INT clockwise from center position will introduce pitch
modulation of the oscillator. With a sine wave selected for the LFO, this
results in a classic vibrato while using the Sample & Hold waveform (S/H)
will create random melodies and, at high speeds, effect-sounds.
Turning LFO INT counterclockwise from center position introduces pulse
width modulation of the oscillator's square waveform. This function is
