This section is what is commonly called a
VCO (Voltage Controlled Oscillator). With
these knobs you have control of pitch and
the choice of several oscillator waveforms
that will determine basic tone color
(timbre).
When the 12 independent TEMPERA
MENT ADJUST knobs are all at their cen-
tral “O” positions, the keyboard will be
tuned to the conventional “well tempered
scale”, These independent tuning knobs let
you tune each note separately
When the FINE and COARSE tuning
knobs are at their center positions also, the
pitch of A will be 440Hz
Vibrato, pitch bends, and the like are prod
uced by frequency modulation (FM); use
the MG-1 INT and EXT INT internal and
external modulation sensitivity knobs to
adjust the intensity (depth) of this modula
tion. The modulation switch turns FM on
and off
Chorus and other effects are produced by
pulse width modulation (PWM). When an
external signal is not patched to the PWM
input jack, MG-2 provides the modulating
signal via the internal (built-in) patch. Turn
the WAVEFORM knob to “ "and
try turning the PWM INT knob (which
adjusts PWM sensitivity) from “0” to “10";
use
the
MG-2
frequency
(FREQ)
knob
to adjust the speed of the modulation. To
get an idea of the amount of variation
available in this and other effects, play one
key near the center of the keyboard and
beginning with the normal setting try turn
ing one knob at a time working from the
top¢down. The maximum input sensitivity
for
frequency
modulation
is
a
1
octave
variation per 1 volt input
