KEYBOARD:
31/2 octave Pratt Read keyboard with second touch and gold
plated contacts. Secona1 touch selects:
• pitch bend + a third
• filter sweep
• vibrato
• Mod. Osc. applied to filter (wah)
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 inter
vals. 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 (approxi
mately = 1/100 of a semitone).
Octave select: ± 1 octave with precision digital divider.
Root pitch wave continuously variable with
n\ r^qj
and intermediate waveshapes available.
Pulse waveshape is modulated from 50% to 10% duty cycles by
filter envelope for increased brightness. Remaining 12 pitch
sources are bright 30% duty cycle pulses.
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 selected waveshapes N\ S\ n_l
plus sampled triangle and sampled sawtooth #.-\ •••:"•-
Light emitting diode indicates rate.
CARD READER:
40 bits with gold plated contacts. Rated for 100,000
card insertions.
CARD PROGRAMMABLE CAPABILITIES:

Filter resonance
Filter mode: low pass, band pass, and high pass.
Filter envelope: attack, decay, and sustain.
Amplifier envelope: attack, decay, and sustain.
Frequency range without vibrato 44Hz — Hz - 4186 Hz
Vibrato amount — adjustable up to ±2 octaves.
Noise: white, selected by indicating push button.
MODIFIERS:
Voltage Controlled Filter
State variable filter continuously variable from low pass thru
band pass and high pass modes.
Frequency range 44Hz (F^ thru 12,000 Hz (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.

Synkey uses quality components throughout.
All potentionmeters 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).
