• To hear the signal generated by the oscillator(s), the
corresponding Osc dial in the oscillator sections must be
turned clockwise to a suitable value.
OSC 1 parameters
Oscillator 1 acts as a master oscillator. It determines the
base pitch for all three oscillators. Oscillator 1 features the
following parameters:
Triangle The Triangle waveform generates only a few harmonics,
spaced at odd harmonic numbers, which produces a
slightly hollow sound.
Sine The sine wave is the simplest possible waveform, with no
harmonics (overtones). The sine wave produces a neu-
tral, soft timbre.
Formant 1–12 Formant waveforms emphasizes certain frequency
bands. Like the human voice, musical instruments have a
fixed set of formants, which give it a unique, recognizable
tonal color or timbre, regardless of pitch.
Vocal 1–7 These are also formant waveforms, but specifically vocal-
oriented. Vowel sounds (A/E/I/O/U) are among the
waveforms found in this category.
Partial 1–7 Partials, also called harmonics or overtones, are a series
of tones which accompany the prime tone (fundamental).
These waveforms could be described as producing inter-
vals with two or more frequencies heard simultaneously
with equal strength.
Reso Pulse
1–12
This waveform category begins with a complex waveform
(Reso Pulse 1), that emphasizes the fundamental fre-
quency (prime). For each consecutive waveform in this
category, the next harmonic in the harmonic series is em-
phasized.
Slope 1–12 This waveform category begins with a complex waveform
(Slope 1), with gradually decreasing harmonic complexity
the higher the number selected. Slope 12 produces a
sine wave (no harmonics).
Neg Slope 1–9 This category also begins with a complex waveform
(NegSlope 1), but with gradually decreasing low fre-
quency content the higher the number selected.
Waveform Description
Parameter Value Description
Osc 1 0–100 This controls the output level of the oscil-
lator.
Coarse +/- 48
semitones
This determines the base pitch used by
all oscillators.
Fine +/- 50 cent Fine tunes the oscillator pitch in cent in-
crements (100th of a semitone). This also
affects all oscillators.
Wave Mod +/- 50 This parameter dial is only active if the
Wave Mod button is activated beside the
waveform selection box. Wave modula-
tion works by adding a phase-shifted
copy of the oscillator output to itself,
which produces waveform variations. For
example if a sawtooth waveform is used,
activating WM will produce a pulse wave-
form. By modulating the WM parameter
with for example a LFO, classic PWM
(pulse width modulation) is produced.
Wave modulation can, however, be ap-
plied to any waveform.
Phase button On/Off When Phase synchronization is activated,
all oscillators will restart their waveform
cycles with every note played. With
Phase deactivated, the oscillators gener-
ate a waveform cycle continuously, which
produces slight variations when playing
as each note will start from a random
phase in the cycle, adding warmth to the
sound. But when synthesizing bass
sounds or drum sounds, it is usually de-
sired that the attack of every note played
sounds the same, so for these purposes
you should activate Phase sync. Phase
sync also affects the noise generator.
Tracking
button
On/Off When Tracking is activated, the oscillator
pitch will track the notes played on the
keyboard. If Tracking is deactivated the
oscillator pitch remains constant, regard-
less of what note is played.
Wave Mod
button
On/Off This switches wave modulation on or off.
