Step 1: Controls
Pre-Wired Connections
The panel silk-screening displays the various connections between modules that
have been pre-wired at the factory.
For example, in the VOLTAGE CONTROLLED FILTER/RESONATOR VCF section, pre-wired
connections from Voltage Controlled Oscillators 1, 2, and 3 into the VCF block
are indicated by the labeled boxes at the bottom of the section:
These labeled, pre-wired inputs correspond to sliders on the panel directly
above the label, which enables adjustment of the incoming signal strength.
The input jacks directly above each labeled box disconnect the pre-wired
connection whenever a 3.5 mm connector is placed into the jack, as indicated
by this graphic:
Voltage Controlled Oscillators (VCOs)
The Voltage Controlled Oscillators (VCOs) electronically generate repeating
wave signals, in a variety of waveforms that can then be shaped, combined, and
filtered
1. INITIAL OSCILLATOR FREQUENCY – This slider chooses a VCO’s coarse
operating frequency in four ranges for audio (10 Hz, 100 Hz, 1 kHz or 10 kHz)
or four sub-audio frequency ranges (.03 Hz, .3 Hz, 3.0 Hz or 30 Hz) when the
VCO operates as a Low-Frequency Oscillator (LFO). To choose between audio and
LFO modes, use the AUDIO/LF sliding switch in the
lower left of each VCO.
2. FINE TUNE – Use this slider to tune the frequency chosen by the
INITIAL OSCILLATOR FREQUENCY slider up or down as needed to find the precise
frequency you need.
3. PULSE WIDTH – Use this slider to set a default width for the
waveform.
4. SYNC ON/OFF – Use these sliding switches to lock VCO2 and/or VCO3
with VCO1 so that the synced oscillators act as a single large oscillator that
follows the frequency of VCO1 to produce complex sounds.
5. OUTPUTS – These output jacks allow you to send out either audio or
LFO signals from the VCOs via cables with 3.5 mm connectors. The type of
waveform is indicated by the silk-screening associated with the jacks
(sawtooth, pulse, sine, triangle, and so on, depending on the specific VCO in
use). The PULSE outputs can also be used to mix in signals from the lower LFO
section (VCO1), the NOISE GENERATOR section (VCO2), or the ADSR ENVELOPE
GENERATOR (VCO3) to produce a composite output signal.
6. AUDIO/LF (KYBD ON/OFF) – This sliding switch chooses between audio
and low (LFO) frequencies for adjustment with the INITIAL OSCILLATOR
FREQUENCY, FINE TUNE, and PULSE WIDTH sliders. When using the VCO as a Low-
Frequency Oscillator, keyboard control is automatically disabled. In the AUDIO
position, keyboard control is enabled.
7. FM CONTROL – Use these inputs to route in external control voltage
signals via cables with 3.5 mm connectors. Placing a connector into one of
these jacks disconnects the corresponding pre-wired connection indicated
directly below the jack.
8. PWM – Use this input when you want to route in external control
voltages to control the pulse width in place of the PULSE WIDTH slider.
Voltage Controlled Filter (VCF)/Resonator Section
The VOLTAGE CONTROLLED FILTER (VCF)/RESONATOR uses a low-pass filter with a
variable cutoff frequency (FC) and resonance (Q). The VCF can be controlled by
panel controls or by voltage control signals.
9. INITIAL FILTER FREQUENCY – This slider sets the low-pass filter to
four coarse frequency points at 10 Hz, 100 Hz, 1 kHz and 10 kHz, which can
then be adjusted via the FINE TUNE slider.
10. FINE TUNE – Use this slider to make further adjustments up or down
from the filter cutoff point set by the INITIAL FILTER FREQUENCY slider.
11. RESONANCE – Use this slider to adjust the filter’s Q setting. At the
MAX setting, the frequency curve below the filter cutoff becomes sharp and the
filter will ring in response to sharp pulses that pass through the filter.
12. MODE (4012/4072) – This sliding switch chooses between two classic
filter circuits, the 4012 filters (the original filter design with a 16 Hz
maximum cutoff frequency) and the 4072 filters (which had a lower maximum
cutoff frequency at 11 Hz).
13. OUTPUTS – This jack allows you to route out the VCF output for use
in other areas of the synthesizer via a cable with a 3.5 mm connector.
14. AUDIO – These inputs allow you to route in audio signals via cables
with 3.5 mm connectors. Each of these inputs breaks the pre-wired connection
when a connector is inserted into the jack.
15. CONTROL – Use these inputs for external control voltage signals via
cables with 3.5 mm connectors. Each of these inputs breaks the pre-wired
connection when a connector is inserted into the jack.
AR/ADSR Envelope Generator Section
These two envelope generators produce controllable, transient waveforms for
use mainly with the Voltage Controlled Filter (VCF) and the Voltage Controlled
Amplifier (VCA).
The AR (Attack-Release) transient generator creates an adjustable transient
envelope every time the generator is activated by a gate or trigger voltage.
The voltage transient is shaped by the ATTACK TIME and RELEASE TIME sliders,
and the AR transient envelope is available at all pre-wired connections with
this label:
16. ATTACK TIME – This slider controls the shape of the note attack up
to an initial fixed peak when a key is depressed or a gate/trigger control
voltage enters the circuit.
17. RELEASE TIME – Use this slider to control the envelope shape
following the key release or release of the gate/trigger voltage.
18. MANUAL – Press this button to manually produce a gate signal to
trigger both the AR and ADSR circuits.
19. TIME FACTOR (x2/x1/x0.5) – Use this sliding switch to choose between
three basic time durations for the overall length of the envelope.
20. ROUTING SWITCH – Use this sliding switch to choose between the S/H
CLOCK pre-wired connection, the GATE IN input or the TRIG IN input. The signal
chosen at this switch is also routed through to the ADSR generator.
21. OUTPUT – Use this jack to send out an additional AR voltage envelope
for use where a pre-wired AR connection is not available.
22. S &H CLOCK – This input allows you to substitute another external
signal for the Sample & Hold circuit’s output via a cable with a 3.5 mm
connector.
23. TRIG IN – This input jack allows you to route in a trigger voltage
via a cable with a 3.5 mm connector.
24. GATE IN – This input jack allows you to route in a gate voltage into
the AR and ADSR circuits via a cable with a 3.5 mm connector.
The ADSR (Attack-Decay-Sustain-Release) transient generator works similarly to
the AR generator, but this circuit creates a more detailed voltage transient
every time the generator is triggered by a gate or trigger voltage. The
voltage transient
is shaped by the ATTACK TIME, DECAY TIME, SUS LEVEL, and REL TIME sliders, and
the ADSR voltage transient is available at all pre-wired connections with this
label:
25. ATTACK TIME – This slider controls the shape of the note attack up
to an initial fixed peak when a key is depressed a gate/trigger control
voltage enters the circuit.
26. DECAY TIME – Use this slider to control how quickly the envelope
drops from the initial fixed peak.
27. SUS LEVEL – This slider controls the level at which the envelope
holds after the initial decay following the fixed peak.
28. REL TIME – Use this slider to control the envelope shape following
the key release or release of the gate/trigger control voltage.
29. TIME FACTOR (x2/x1/x0.5) – Use this sliding switch to choose between
three basic time durations for the overall length of the envelope.
30. OUTPUT – Use this jack to send out an additional ADSR voltage
envelope for use where a pre-wired ADSR connection is not available.
31. GATE IN – Use this jack to route in a gate signal via a cable with a
3.5 mm connector.
32. MANUAL – Press this button to manually produce a gate signal to
trigger both the AR and ADSR circuits.
33. ROUTING SWITCH – Use this sliding switch to choose between the S/H
CLOCK pre-wired connection, the GATE IN input, or the TRIG IN input. The
signal chosen at this switch is also routed through to the ADSR generator.
Voltage Controlled Amplifier Section
The Voltage Controlled Amplifier (VCA) offers further tone-shaping
possibilities in parallel with the Voltage Controlled Filter (VCF) before both
are blended in the Mixer section. At maximum gain, the VCA passes signals
through at unity gain. At minimum gain, the VCA circuit will not pass a
signal.
34. INITIAL GAIN – This slider sets the overall gain for the VCA
circuit. 35. AUDIO – Use these inputs to route audio signals into the VCA and
adjust the signal gain using the slider immediately above the inputs.
Inserting the 3.5 mm connectors into the jacks will disable the pre-wired VCF
and RING MOD connections.
36. CNTRL (LIN/EXPL) – These inputs can accept control voltage signals
via cables with 3.5 mm connectors. The left input has a linear response, while
the right input features an exponential response. Inserting 3.5 mm connectors
into these jacks will disable the pre-wired AR and ADSR connections.
37. OUTPUT – Use this output to route the final VCA signal out for use
where a pre-wired VCA signal is not available.
Mixer/Reverb Section
The Mixer section accepts two inputs that are balanced via the two sliders and
then summed into a single signal. After being ummed, the combined signal can
then be panned before going to the stereo outputs. The Mixer section is
prewired with
inputs from the VCF and VCA.
NOTE: 2600 uses a digital reverb, while BLUE MARVIN features a real, onboard
spring reverb.
38. AUDIO – Use these two inputs to route audio signals into the Mixer
via cables with 3.5 mm connectors. Inserting 3.5 mm connectors into these
jacks will disable the pre-wired VCF and VCA connections.
3.9. POST-ATTENUATOR OUTPUTS – These two outputs allow you to send
signals out immediately following the attenuator sliders, which means the
sliders can be used to attenuate audio or control voltage signals for use
elsewhere.
40. POST-MIXER OUTPUT – This input breaks the signal connection from the
Mixer to the PAN slider when a 3.5 mm connector is inserted. Use this input to
route in an outside signal for use by the PAN slider. The Mixer output still
goes to the Reverb circuit via a pre-wired connection.
41. PAN – Use this slider to place the summed Mixer signal where desired
in the left-right stereo field before final output.
42. MIXER OUT – This output is an additional Mixer output that taps the
prewired Mixer connection
which feeds into the Reverb circuit.
43. REVERB OUT – This output taps the right Reverb signal for use
elsewhere.
44. LEFT INPUT – Use this input to add an additional signal to the
Reverb circuit’s left output. The additional signal will be summed with the
left Reverb output and panned hard left in the stereo field.
45. RIGHT INPUT – Use this input to add an additional signal to the
Reverb circuit’s right output. The additional signal will be summed with the
right Reverb output and panned hard right in the stereo field.
46. L OUTPUT/R OUTPUT – The final stereo left-right outputs each have
matching parallel pairs of ¼” and 3.5 mm connections. The ¼” outputs can be
used to send the final mix to external amplifiers, speakers, or other
processing equipment. The parallel 3.5 mm jacks can be used to send the left
and right outputs to other synth circuits for further processing.
Keyboard/Portamento Section
The Keyboard section determines how the built-in Low-Frequency Oscillator
(LFO) unit works with an external keyboard.
The keyboard control voltage is available as a pre-wired connection wherever
you see this label:
47. TRIG OUT – Use this output to send out a trigger control voltage for
use elsewhere via a cable with a 3.5 mm connector.
48. GATE OUT – This output can be used to send out a gate control
voltage via a cable with a 3.5 mm connector.
49. UPPER VOICE – This output sends out a control voltage based on the
highest note being played on the keyboard while in DUO voice mode.
50. KYBD CV – This output sends out the complete keyboard control
voltage signal for use elsewhere.
51. VOICE MODE(MONO/DUO) – Use this sliding switch to determine whether
the keyboard plays one voice at a time (MONO) or two voices simultaneously
(DUO).
52. REPEAT (KYBD/OFF/AUTO) – Use this sliding switch to control how the
keyboard sends trigger signals. When the switch is set to the KYBD position,
the keyboard will send out repeating trigger pulses as long a key is held
down. In the AUTO setting, the keyboard will send out a stream of trigger
pulses based on the synthesizer’s LFO setting. When the switch is in the
center OFF position, the keyboard will generate only one trigger pulse per
keypress (i.e., the keyboard will revert to “normal” keyboard functionality).
53. TRIG MODE (SINGLE/MULT) – When this switch is set to SINGLE, the
keyboard will only generate a trigger pulse when a key is played while no
other keys are being played. In MULT mode, the keyboard will generate a
trigger pulse every time any key is pressed down, even if previously pressed
keys are held down.
The Portamento function allows one pitch to change gradually to a second pitch
at a predetermined rate.
54. ON/OFF – This switch turns the Portamento function on or off.
55. MOMEN – Pressing this button temporarily activates the Portamento
function for as long as the button is held down.
56. MAX/MIN – This slider controls the strength of the Portamento
effect. The MAX setting provides the most gradual and smooth effect.
Low-Frequency Oscillator (LFO) Section
The unit includes a purpose-built Low-Frequency Oscillator (LFO) primarily
meant to function with a keyboard. The LFO has a pre-wired connection to VCO1,
as indicated by this label:
57. LFO (SAW) – This output allows you to route a sawtooth LFO signal
out for use elsewhere via a cable with 3.5 mm connectors.
58. LFO (SQUARE) – This output allows you to route a square wave LFO
signal out for use elsewhere.
59. EXT VIB IN – This input allows you to route in an external LFO
signal for blending with the delayed LFO sine wave.
60. LFO (SINE) DELAYED – This output can be used to send out a copy of
the LFO’s pre-wired sine wave output for use elsewhere. This output signal is
delayed at a rate controlled by the VIB DELAY slider.
61. LFO SPEED – Controls the base speed of the LFO oscillation.
62. VIB DELAY – This slider controls the amount of delay applied to the
LFO sine wave.
63. VIB DEPTH – This slider controls the intensity of the vibrato effect
created by the delayed sine wave LFO signal.
Envelope Follower Section
The Envelope Follower generates an output voltage based on an input signal,
depending on the average amplitude of the input signal. The generated control
voltage’s characteristics can be adjusted to create various effects when the
output is routed to the VCF, VCA or the VCOs.
The input signal can be adjusted via the Preamp, which feeds into the Envelope
Follower via a pre-wired connection.
The Envelope Follower’s output does not have a pre-wired connection to other
sections of the synthesizer.
(64) PREAMP INPUT – Use this input to route an external signal into the
Preamp via a cable with a 3.5 mm connector.
(65) RANGE (X1000/X100/X10) – Use this sliding switch to determine the
the base amount of amplification applied to the input signal and then adjust
via the GAIN slider.
(66) GAIN – This slider determines how strongly the input signal is
amplified.
(67) PREAMP OUTPUT – This output sends out a copy of the Preamp signal
for use elsewhere in the synth.
(68) PREAMP INPUT – This input allows you to bypass the Preamp and route
an external signal directly into the Envelope Follower. Alternately, the
input signal can be blended with the signal coming into the Envelope Follower
via the pre-wired connection.
(69) SENSITIVITY – This slider controls the sensitivity of the Envelope
Follower circuit.
(70) OUTPUT (ENVELOPE FOLLOWER) – Use this output to route the final
Envelope Follower signal out for use elsewhere in the synthesizer via a cable
with a 3.5 mm connector.
Ring Modulator Section
The Ring Modulator is a voltage multiplier that combines two input signals to
produce a variety of exotic timbres. By default, the two pre-wired signals
come into the circuit from VCO1 (sawtooth) and VCO2 (sine). The Ring Modulator
output is available as a pre-wired connection wherever you see this label:
(71) VCO 1 – This input jack allows you to route in an external signal for
blending with the pre-wired VCO1 sawtooth signal. The overall gain for this
combined signal is adjusted by the adjacent slider.
(72) VCO 2 – This input jack allows you to route in an external signal
for blending with the pre-wired VCO2 sine wave signal. The overall gain for
this combined signal is adjusted by the adjacent slider.
(73) AUDIO/DC – Use this switch to optimize the VCO1 signal path for
audio (AUDIO) or control voltage (DC) signals.
(74) RING MOD OUTPUT – This jack can be used to send out the final,
summed Ring Modulator for use elsewhere where a pre-wired connection is not
available. (75) COLOR – Use this slider to move between white noise
(WHITE), pink noise (PINK), and low-frequency noise (LOW FREQ).
(76) LEVEL – This slider controls the overall attenuation of the noise
signal prior to output.
(77) NOISE GENERATOR OUTPUT – Use this output to send the final noise
signal out for use in the synth where a pre-wired connection is not available.
Voltage Processor Section
The Voltage Processor offers three different processors for both audio and
control voltage signals. Two of the processors are for mixing and inverting
signals, while the third processor applies a variable lag to the signal. The
Voltage Processor’s output is not available elsewhere in the synth as a
prewired signal, and so requires cables.
(78) MULT – These linked parallel connections can be used as a patch bay
to duplicate and combine signals. The MULT connections can function as both
inputs and outputs.
Inverter 1
Inverter 1 accepts four different inputs, which are summed and then inverted.
For example, a +10 V input to INPUT 1 will leave Inverter 1 with a value of
-10 V, while an audio signal will be output with the phase reversed 180°.
(79) -10 V – This input attenuates the input signal by 10 V.
(80) KYBD CV – This input is optimized for a control voltage signal from
a keyboard.
Inverter 2
Inverter 2 can accept two signals, which are then summed and inverted for
output.
(81) +10 V – This input boosts the input signal by +10 V.
Lag Processor
The Lag Processor responds to sudden changes in input voltage and slows down
those changes by an amount controlled by the slider. For audio signals, the
Lag Processor will cut off treble frequencies by increasing amounts, similar
to a lowpass filter.
(82) ENV FOLL – This input can accept both control voltages and audio
signals but is optimized to process the Envelope Follower output signal.
(83) LAG – This jack sends out the final signal from the Lag Processor.
Sample & Hold/Electronic Switch Section
Sample & Hold
The Sample & Hold circuit takes an input signal and converts that signal into
a stepped output by taking samples of the input signal at set intervals. For
example, a smooth sine wave input will appear at the output as a squared-off,
approximate version of the original smooth waveform. This stepped waveform can
then be sent other areas of the synthesizer to create exotic sounds and
textures.
This Sample & Hold circuit has an internal clock generator and a pre-wired
connection from the Noise Generator circuit.
The Sample & Hold circuit’s output is available as a pre-wired connection
wherever you see this label:
(84) NOISE GENERATOR – This input jack interrupts the Noise Generator
input signal when a 3.5 mm connector is inserted into the jack. Use this jack
to substitute another signal for the Noise Generator signal.
(85) INT CLOCK OUT – Use this jack to export the internally generated
clock signal for use in other parts of the synthesizer.
(86) S/H OUT – Use this jack to send out the Sample & Hold circuit’s
final signal for use elsewhere in the synthesizer where a pre-wired
connection is not available.
(87) EXT CLK IN – This jack can be used to import an external clock
signal to run the Sample & Hold circuit. Placing a 3.5 mm connector into this
jack will disable the internal clock generator. Any square or pulse wave
generated in other areas of the synthesizer, as well gate or trigger signals
from the keyboard can be routed into this jack and used as a clock signal.
(88) LEVEL – This slider attenuates the input signal before it goes into
the Sample & Hold circuit.
(89) RATE – This slider controls the speed of the internal clock
generator and therefore controls how often the Sample & Hold circuit takes a
measurement of the input signal. When the internal clock signal is interrupted
by use of the EXT CLK IN input, the RATE slider will not function.
Electronic Switch
The Electronic Switch connections are bidirectional. This circuit can
alternate a single input from C between the A and B outputs, or the circuit
can route two signals into the A and B jacks and then alternate the C output
between the A and B input signals. The rate of back-and-forth switching in
both of these scenarios is controlled by the Sample & Hold circuit’s internal
clock (or an external clock source-routed in through the EXT CLK IN jack.
(90) ELEC SWITCH A/B/C – These jacks route signals in and out over cables
with 3.5 mm connectors.
Phones/Power
(91) PHONES – Use this jack to connect headphones that use 1/8” plugs and
control the output level with the knob immediately below the jack. The
headphone jack is connected to the Mixer output.
(92) POWER – Press this switch to turn the synthesizer on or off. Make
sure all the connections are made before turning on the unit.
Back Panel (93) LED
– Use this rotary knob to control the brightness of the LEDs on the front
panel.
(94) INTERVAL LATCH – Use this ¼” jack with an external footswitch to
temporarily turn on the interval function. When the VOICE MODE switch is in
the DUO position, playing two notes and depressing the footswitch maintains
the two-note interval while you play further single notes.
(95) PORTAMENTO FOOTSWITCH – Use this ¼” jack with an external footswitch
to turn the Portamento function on or off.
(96) MIDI CHANNEL SWITCHES – These 4 switches allow you to set the MIDI
Channel number from 1 to 16 (see the table printed in this document or refer
to the silk-screened switch matrix printed on the back panel).
(97) MIDI IN – This port receives MIDI data from an external source over
a 5-pin DIN connector. This external source will commonly be a MIDI keyboard,
an external hardware sequencer, a computer equipped with a MIDI interface, and
so on.
(98) MIDI THRU – This port uses a 5-pin DIN jack is used to pass through
MIDI data received at the MIDI IN jack. This MIDI data will commonly be sent
to another synthesizer or to a drum machine assigned to a different MIDI
Channel.
(99) USB PORT – This jack allows connection to a computer over a USB type
B connection. This synthesizer will show up as a class-compliant USB MIDI
device, capable of supporting MIDI in and out.
(100) DC INPUT – Connect the supplied 12V DC power adapter here. The
power adapter can be plugged into an AC outlet capable of supplying from 100V
to 240V at 50 Hz/60 Hz. Use only the power adapter supplied.
