Select the parameter "LFO=XX." Now, use the arrow buttons to adjust the
modulation amount. Modulation amount can be positive or negative. A
modulation amount of +00 has the same effect as turning the modulator <OFF>.
Hint: With modulation amount, as with all parameter values that have a center value,
there is an easy way to reach that value. With the "LFO=XX" selected, press the
Down Arrow button, and while holding it down, press the Up Arrow
button, then release both buttons. This automatically sets the modulation amount
to +00. Similarly, you can reach maximum and minimum values by holding the
appropriate Up or Down Arrow button (depending on the direction you wish
to go) then pressing either the Left or Right Arrow button.
Modulation Sources
The 15 Modulation Sources available on the SQ-R are as follows:
LFO — Low Frequency Oscillator
ENV 1 — Envelope 1
ENV2 — Envelope 2
AMP — Envelope 3 (Amp)
NOISE — Noise Generator
NOISE 2 — Noise 2
VELOC —Velocity
KEYBD — Keyboard Tracking
TIMBRE — Timbre
PEDAL — Voltage Control Foot Pedal
PITCH — Pitch Bend Wheel
XCTRL — External Controller (MIDI)
WHEEL — Modulation Wheel
PRESSR — Pressure (MIDI)
MAX ON —Full Value
OFF —Off
• LFO — Low Frequency Oscillator
The Low Frequency Oscillator generates only very low frequency waves,
below the audio spectrum, which can produce vibrato, tremolo, and many other
effects depending on the LFO wave selected and where it is applied as a
modulator. There are seven possible wayeshapes for the LFO. See the LFO
Screen later in this section for a complete discussion of the LFO.
• ENV 1, ENV 2, (AMP)
The SQ-R has three complex Envelopes. Envelopes are used to create changes
over time, in pitch, brightness, volume, etc.
• ENV 1 is permanently routed to the pitch of the voice, though it can be
assigned as modulator elsewhere if you wish.
• ENV 2 is permanently routed to the filter cutoff frequency. It also can be
assigned as a modulator elsewhere.
• AMP is a special case. AMP always controls the volume or amplitude of the
voice and cannot be selected as a modulator anywhere else.
A discussion of the SQ-R Envelopes follows later in this section.
• NOISE — Noise Generator
The Noise generator creates a randomly changing level. It is useful for
modulating, among other things, the pitch of a voice (Pitch Mod screen).
Applied to pitch with large modulation amounts it tends to create strange
"computer sound" effects. Small modulation amounts (around +02 to +04) can
create a subtle random movement in the sound, which imparts a more natural
quality.
• NOISE 2 — Smooth Noise Generator
This second Noise generator works on the same principles as NOISE, but
NOISE 2 has a "smoothed" wave pattern. When applied to pitch, NOISE 2 has
a siren-like quality, as compared to NOISE's computer effects. The following
illustration shows the differences in the two Noise generators wave shapes.
