Oscillators are the biogenesis of Analog synthesis,
producing periodic or regularly repeating waveforms
—familiar pitched sounds when in the right range.
Tuning controls alter the frequency or pitch of the
oscillators, whereas wave shape selectors, Pulse
Width, and Sync controls shape the harmonic
spectrum of the signal, its basic timbre, or tone
color.
Waveform Characteristics
Triangle:
Fluty, with odd harmonics like the Square
wave, but its amplitude is quite weak in comparison
to its fundamental. The Triangle possesses more
brilliance than the similarly shaped sine.
Sawtooth:
Bright, buzzy, brassy—the richest
harmonically—containing both even and odd
harmonics of the fundamental frequency. A very
smooth tone is yours with a low-pass
fi lter on tap.
Square:
In its even state, it is a full bouncy sound—
a bass beast for many. Near the edges of its duty
cycle, or width, the beloved becomes a “clavi,”
reedy, nasal a
ff air, with odd harmonics only. The
(wide rectangle) introduces even numbered
harmonics changing the overall harmonic mix. The
(narrow rectangle) hypes lower numbered harmonics
—both odd and even.
FREQUENCY 1, 2, 3
Controls the pitch of each oscillator. Stepped (quantized) in semi-tones over a fi ve octave range.
FINE 2, 3
Controls the fi ne tune of oscillators 2 & 3. PANEL 2 FINE tune shortcut: Press and hold PANEL 2 (left bottom of
C ONTROL section) then rotate FREQUENCY 2 / 3.
WAVEFORM SWITCHES
Triangle, Sawtooth and Pulse Waves can be selected individually or combined for more complex shapes.
PARA
Allows the 3 oscillators to be played by 3 di ff erent MIDI notes; all 3 oscillators share the same VCF and VCA, so it's not
truly polyphonic, but with some care and creativity in programming, or even live playing, fancy colors and engaging
