PULSE WIDTH MODULATION – the fader
(25)
adjusts the level of pulse width modulation
of VCO-2. The switch selects between LFO
sinewave or the ADSR envelope as the source
of pulse width modulation.
LFO and S/H Section
RATE LED – this LED flashes at the rate of the
(26)
low frequency oscillator (LFO) frequency.
LFO FREQ – adjust the frequency of the LFO.
(27)
The LFO can be used for FM and pulse width
modulation of VCO-1 and VCO-2, to trigger
the S/H, modulate the VCF, and vary the
REPEAT rate.
S/H MIXER FADER (VCO-1 saw or pulse)
(28)
– the fader adjusts the input level to the
sample/hold. The switch selects between
VCO-1 sawtooth or pulse waveform as the S/H
input source.
S/H MIXER FADER (Noise or VCO-2 pulse)
(29)
– the fader adjusts the input level to the
S/H. The switch selects between the internal
Noise or VCO-2 pulse waveform as the S/H
input source.
S/H TRIGGER (LFO or KYBD) – select if the
(30)
S/H is triggered by the LFO or by the keyboard.
NOISE GEN (WHITE or PINK) – select the
(31)
internal noise generator between white noise
or pink noise.
OUTPUT LAG – adjust the sample and hold
(32)
output lag time.
Sequencer Section
SEQUENCER – see details on page 17 and 44.
VCF Section
VCF FREQ – adjust the cutoff frequency of the
(33)
voltage controlled filter (VCF). Frequencies
above the cutoff are attenuated.
VCF RESONANCE – adjusts the amount of
(34)
volume level boost (resonance) given at the
cut-off frequency.
VCF MODE – choose from three classic filter
(35)
types: 2-Pole (4023), 4-Pole (4035), and 4-Pole
(4075).
HPF CUTOFF FREQ – adjust the cutoff
(36)
frequency of the high-pass filter (HPF).
Frequencies below the cutoff are attenuated.
DRIVE ON/OFF – turn the drive on and off.
(37)
VCA GAIN – adjust the gain of the voltage
(38)
controlled amplifier (VCA). The output is not
triggered by the keyboard.
AUDIO MIXER Section
NOISE/ RING MOD – the fader adjusts the
(39)
level of noise or ring modulation added to the
overall mix. The switch selects between the
internal noise generator and ring modulation.
VCO-1 (saw or pulse) – the fader adjusts the
(40)
level of VCO-1 added to the overall mix. The
switch selects between the VCO-1 sawtooth or
pulse waveforms.
VCO-2 (saw or pulse) – the fader adjusts the
(41)
level of VCO-2 added to the overall mix. The
switch selects between the VCO-2 sawtooth or
pulse waveforms.
VCF Section
KYBD CV / S/H Mixer or Pedal – the fader
(42)
adjusts the level of effect on the VCF. The
switch selects the source affecting the VCF,
either the keyboard control voltage or the S/H
Mixer, or an optional pedal.
S/H or LFO – the fader adjusts the level
(43)
of effect on the VCF. The switch selects the
source affecting the VCF, either the S/H or the
LFO sinewave.
ADSR or AR – the fader adjusts the level of
(44)
effect the AR or ADSR envelopes have on the
VCF. The switch selects either the ADSR or AR
envelope. This switch, and a similar switch in
the VCA section, allows you to control the VCF
and VCA with separate envelopes if desired.
VCA Section
AR or ADSR – the fader adjusts the level
(45)
of effect the AR or ADSR envelopes have on
the VCA. The switch selects either the ADSR
envelope or the AR envelope.
AR and ADSR Envelopes
When applied to the VCA, the AR and ADSR
envelopes are used to control the level of the note
being played over time.
When applied to the VCF, the AR and ADSR
envelopes are used to control the cut-off frequency
of the filter for each note played over time.
In addition, the AR and ADSR envelopes can also
affect the VCO-1 and VCO-2 FM modulation and pulse
width modulation.
Note that the ATTACK, DECAY and RELEASE stages are
measured in units of time, and the SUSTAIN stage is
measured in units of level.
Quick Start Guide
AR Section
The AR controls are similar to the ADSR
controls if they are set to: Decay = Zero, and
Sustain = Maximum.
A-ATTACK – this adjusts the time for the level
(46)
to reach maximum after a key is pressed.
R-RELEASE – this adjusts the time it takes for
(47)
the signal to decay once the key is released.
ADSR Section
A-ATTACK – this adjusts the time for the level
(48)
to reach maximum after a key is pressed.
D-DECAY – this adjusts the time to decay
(49)
down to the SUSTAIN level after the attack
time is over.
S-SUSTAIN – this sets the sustain level
(50)
reached after the attack and decay time
are over.
R-RELEASE – this adjusts the time it takes for
(51)
the signal to decay once the key is released.
KYBD/LFO Repeat Section
ADSR KYBD GATE/LFO REPEAT – set to ADSR
(52)
KYBD GATE in normal use. If set to LFO REPEAT,
then notes will repeat at the tempo set by the
LFO Frequency, either when a note is played,
or automatically, depending on the setting of
the KYBD REPEAT/AUTO REPEAT switch.
KYBD REPEAT / AUTO REPEAT – If either of
(53)
the adjacent switches are set to LFO REPEAT,
then notes will repeat at the tempo set by the
LFO Frequency, either when a note is played
(KYBD REPEAT position), or automatically
(AUTO REPEAT position).
AR KYBD GATE/LFO REPEAT – set to
(54)
AR KYBD GATE in normal use. If set to LFO
REPEAT, then notes will repeat at the tempo
set by the LFO Frequency, either when a
note is played, or automatically, depending
on the setting of the KYBD REPEAT/AUTO
REPEAT switch.
