Technical Specifications
KEYBOARD: 3Vz octave Pratt Read
keyboard with. Second Touch and gold
plated contacts. Pitch bend + a third, filter
sweep, vibrato, Mod. Osc. applied to filter
(wan).
Any combination may be selected.
Portamento variable from 0 to 2 seconds per
octave (may be selected by optional
footswitch or controlled from optional pedal).
SOURCES: A Master oscillator generates 13
pitches at semitone intervals. Pitches are
selected by indicator push buttons. Any
combination of semitones may be selected
within the octave.
Accuracy'of pitch interval: 1.2 cents
maximum (approximately = 1/100 of a
semitone). Octave select: ±1 octave with
precision digital divider. Root pitch wave
continuously variable with
_n J A si aa (\) ru
and intermediate waveshapes available.
Pulse waveshape is modulated from 50% to
10% duty cycle by filter envelope for
increased brightness. Remaining 12 pitch
sources are bright 30% duty cycle pulses.
Frequency range without vibrato 44Hz —
4186Hz. Vibrato amount — adjustable up to
±2 octaves. Noise: white, selected by
indicating push button.
MODIFIERS: Voltage Controlled Filter. State
variable4itt§r continuously variable from low
pass thru band pass and high pass modes.
Frequency range 44Hz (F,) thru 12000Hz, or
12KHz (Gg). Inputs: (1) filter envelope 0 to
+ 5 octave sweep. (2) modulation oscillator 0
to ± 3 octaves.
Ring modulator— Digital with modulation
pitch tracking a 5th above root pitch. Other
timbres may be selected by using other than
root pitch source.
CONTROLLERS: Envelopes - 1 for filter, 1
for voltage controlled amplifier, each with
attack, decay and sustain controls. Attack:
.005 to 3 sec. Decay: .002 to 9 sec.
Modulation Oscillator: Variable rate from .15
cycles/second to 50 cycles/second. 5 switch

Output volume.
Output: High and low outputs of 4 and .4
volts nominal range suitable for driving
standard music and hi-fi amplifiers.
WARM-UP: 3'/2 minutes at normal
temperatures.
POTS AND SWITCHES: All potentiometers
are Allen Bradley and are sealed against
contaminents. Allen Bradley pots are rated at
100,000 rotations and become quieter with
use. All switch contacts are gold and silver
plated (excludes power switch).
SIZE: 29" x 7" x 8"
WEIGHT: 26 lbs.
POWER REQUIREMENTS: 10 watts
