Vco1/2 Pitchscale; Vco1/2 Wave; Vco1/2 Edge - Yamaha EX5 Owner's Manual

VCO1/2 PitchScale

Sets the Pitch Scale for each VCO1/2 oscillator. The
Pitch Scale function corrects the pitch change of
VCO1/2 in accordance with the notes played on the
keyboard. When VCO1/2 Pitch Scale is applied, the
pitch change is increased or decreased relative to the
specific pitch, which is designated here as MIDI note
number 64 (E3).
Settings: –64~0~+63

VCO1/2 Wave

Selects the wave for each VCO1/2 oscillator. Waves
available for VCO1 depend on the current Sync
status (on/off).
Settings:
VCO1 (when Sync is set to on: other than only FM):
saw, pulse, innr1/2/3 (inner1/2/3)
VCO1 (when Sync is set to off: only FM): saw, pulse,
saw2, mix
VCO2: saw, pulse, saw2, mix
saw (Sawtooth wave)
As seen in the diagram, this wave derives its name from its
shape, and is used to create a brass instrument sounds such as
trumpet and strings such as violin. Since it contains all
harmonics in the spectrum, it produces a full rich sound.
When used with the Pulse Width function (see page 116),
increasing the even harmonics can raise the pitch to a
maximum of a full octave.
Basic Wave
pulse (Pulse wave)
The pulse (square) wave, familiar as dial tone of touch-tone
phone, is used to make woodwind instrument sounds. When
the Pulse Width is set to 64, the waveform will contain only
odd-numbered harmonics.
Basic Wave
PW=below 64
115
saw2 (Sawtooth2)
This wave is slightly different from the saw wave. The
spectrum of the saw2 wave is created by a sawtooth wave
combined with a pulse wave, and therefore. When the Pulse
Width is set to 64, the wave shape is the same as the saw. As
you change the Pulse Width, the even-number harmonics
increase and the saw wave volume becomes larger. Even if the
pitch is raised an octave, the basic pitch remains the same.
Basic Wave
mix (Mix)
This mix wave is a mix of the saw and pulse waves.
Pulse Saw
Innr1 (Inner1: Inner1)
Innr2 (Inner2: Inner2)
Innr3 (Inner3: Inner3)
Active when the Sync function is on. This waveform is
output according to the Sync's structural formula. These
three types are effective when used with the Pulse Width.

VCO1/2 Edge

Adjusts the shape of each VCO1/2 wave. The larger
the value, the sharper the wave becomes, whereas
the smaller the value, the rounder and softer the
wave becomes. This parameter can make the sound
harsher or softer.
Settings: 0~127
Sharper wave Rounder wave
PW=below 64
