SPECIFICATIONS
I
Keyboard
61 Keys, C
through

(5
octaves).
Transposition

for
each channel.
Nominal

fronn
1
octave below
nominal
(16')
to 2
octaves above
(2'}.
Available Fundamental
Frequency Range
(Harmonics
higher
than these specified
frequencies may be present,
although
not
specifled.)
32Hz to
8kHz
(from
16'
and
lowest note
on keyboard to
2'
and
highest
note on the
keyboard,
PITCH controls
centered
and ribbon controller not
in use).
OH
2
to
1 1kHz
(approx.)
using
the
PITCH
controls and
ribbon
controller to extend the lowest
and highest key-
board
pitches.
Pitch
Tuning
Range
COARSE TUNE:
approximately 1 octave
(-500
cents
to
+700
cents).
FINE TUNE:
approximately
±1
semi-tone
(±30 cents).
DETUNE CM II:
channel
II
may
be offset in
pitch
from
channel
I by
approximately
±1
semi-tone.
Simultaneous Notes
Up to
8 notes may be
played
simultaneously. However,
since each note played can cause
separate voices to be
generated by
the
two
channels,
up to
16
notes actually
may
be heard at
once.
Simultaneous Voices
Two
independent voices may
be
generated,
one on
channel I and one
on
channel
i
I;
a
MIX control assigns
either
voice,
or any blend of the two,
to
additional
synthesizer circuitry and ultimately
to
the
outputs.
Total Number of
Voices
Each
channel
is
provided with
1
1
different
preset patches,
two
memory-programmable patches, and one
panel
programmable patch.

(VCF-EG
&

Attack Time:
1 millisecond
(min.), 1 second (max.).
Decay

10
milliseconds (min.), 10
seconds (max.).
Release
Time:
10 milliseconds (min.), 10

Glissando/Portamento
Time Range
10
seconds maximum to
change oscillator
frequency
from
the
lowest
to
the highest note
on
the
keyboard.
Ring
Modulator
Simultaneous, sine-wave ring
modulation of
all
outputs.
Variable
SPEED, depth of
MODULATION.
Envelope
Generator
for varying
the
speed
of
the
Ring Modulator
has
variable
ATTACK
TIME, DECAY TIME,
and
DEPTH
of
speed
change.
Sub Oscillator
Functions
Sine wave,
sawtooth
wave,
inverted sawtooth,
square wave,
white noise, or an
external input can
be used
to
modulate
any combination
of
the
following:
VCO,
VCF, VCA.
Modulation
is
applied equally
to
both
voices and
all
notes
played. SPEED (frequency) range
is
adjustable from
0.7Hz to 60Hz.
Velocity Sensitive Touch Response ("INITIAL"
effects)
Individual channel programming
controls increase
the
LEVEL (volume)
and/or
BRILLIANCE (filter
cutoff
frequencies)
as keys are pressed faster; control to increase
the amount
of
PITCHBEND (oscillator pitch
change) for
any voices
being
played.
Pressure
Sensitive Touch Response
("AFTER" effects)
Individual channel programming
controls increase the
LEVEL
(volume)
and/or
BRILLIANCE
(filter cutoff
frequencies)
as
keys
are
pressed down harder; controls
to
increase the
sub
oscillator SPEED (frequency), the amount
of
sub oscillator modulation
of
the
VCO,
or the amount
of
sub oscillator modulation of
the
VCF for
any
voices
being played.
External
Input Characteristics
Unbalanced, standard
1/4"
phone jack.
50-kohm

(for
low
or
high
impedance sources). Nominal
sensitivity
10
millivolts rms (30mV
peak-to-peak) with

i.e., 10mV rms sine wave
external input would produce
the same amount

as
the
maximum
from the built-in
sub oscillator.
