Thank you for purchasing the Erica Synths SYNTRX II synthesizer!
Peter Zinovieff himself approved of our re-imagination of his legendary Synthi
AKS in the form of the SYNTRX which was produced in a limited run of 1056
units. Based on lessons learned from the SYNTRX, we decided to create an
instrument which would integrate even deeper into contemporary electronic and
experimental music setups and cover sonic territory from daunting drones to
powerful basslines and glitched noisescapes.
The SYNTRX II is the culmination of our analogue sound design circuits two
perfectly stable main oscillators with waveshapers, a versatile multimode
filter, supercharged external instrument inputs with an envelope follower, a
unique, great sounding ringmodulator, a recordable joystick and built-in piano
roll sequencer, all arranged around our signature matrix mixer and topped off
with powerful FX on our new DSP platform. Introducing The SYNTRX II – a new
dark horse for experimental sonic rides.

THE INTERFACE
The SYNTRX II, like most synthesizers built around a patch matrix, is somewhat similar to a modular synthesizer here you can modulate any available “module” with another and possible connections are almost limitless (it does not mean, however, that every connection will produce sound). The mixer/splitter matrix allows for mixing of up to 16 signals to one output and likewise because all inputs and outputs are buffered splitting one signal to 16 destinations.

THE “MODULES”
As mentioned above, using the matrix patchbay on the SYNTRX II, you can build
patches and achieve unconventional modulations. In order to fully understand
the functionality of the SYNTRX II, let’s take a closer look at the individual
“modules”.
OSCILLATOR 1
OSCILLATOR 1 is primarily an audio rate oscillator and without an external CV
applied, it generates sine and pulse waves at frequencies from approximately
C0 to C8. The OCTAVE switch allows for offsetting the oscillator three octaves
up or down. The TUNE knob allows for fine-tuning the pitch of the oscillator
in an approximately two octave range. Each wave has manual and CV control over
the waveform. By turning the SHAPE knob, the pulse wave changes pulse width,
while the sine wave changes shape from pure sine in the 0 setting to inverted
sharkfin when turned counter-clockwise and sharkfin when turned clockwise.
SQUARE
LEFT CENTRE RIGHT
SINE
Moreover, if OSCILLATOR SHAPE CV is applied to the relevant matrix input, the
OSC1 SHAPE switch determines which wave is being modified by the incoming CV.
In the middle setting, both waves are shaped, in the left setting pulse width
modulation is applied, in the right setting the sine wave is shaped. Please
note that incoming CV is added to the SHAPE knob position. Each waveform has
its LEVEL control and each wave is sent to an individual matrix input. This is
very handy if you design drones and wish to send each wave to an individual
output. Oscillator 1 is controlled via the CV1 input, and an external CV is
added to the TUNE/OCTAVE knob setting.

OSCILLATOR 2
OSCILLATOR 2 is also primarily an audio rate oscillator and without external
CV applied, it generates pulse and saw waves at frequencies from approximately
C0 to C8. The OCTAVE switch allows for offsetting the oscillator three octaves
up or down. The TUNE knob allows for fine-tuning the pitch of the oscillator
in an approximate two octave range. Each wave has manual and CV control over
the waveform. By turning the SHAPE knob, the pulse wave changes pulse width,
while the saw changes shape from saw if the SHAPE knob is all way counter-
clockwise to dual super saw when all the way clockwise.

Moreover, if OSCILLATOR SHAPE CV is applied to the relevant matrix input, the
OSC2 SHAPE switch will determine which wave is being modified by the incoming
CV. In the middle setting no wave shaping is applied, in the left setting –
pulse width modulation is applied, in the right setting – a saw wave is
shaped. Please note, that incoming CV is added to the SHAPE knob position.
Each waveform has its LEVEL control and both waves are mixed before they are
sent to the single matrix input.
Oscillator 2 can be free-running or synchronized to Oscillator 1 if the SYNC
switch is in the right position.
If external CV is applied only to the CV1 input, Oscillator 2 is controlled
via the CV1 input, but if CV2 is used, it takes over control of Oscillator2;
an external CV is added to the TUNE/OCTAVE knob setting.

OSCILLATOR 3
OSCILLATOR 3 is primarily a low-frequency oscillator that goes into the audio
range and without an external CV applied, it generates pulse and triangle
waves at frequencies from 0.05 Hz to 500 Hz, adjustable by the TUNE knob. Both
waves have independent points on the patch matrix with an adjustable LEVEL for
each wave and both waves have manually adjustable SHAPE. Depending on FREE/KEY
FOL switch position, Oscillator 3 can be either free-running or controlled via
external CV (key follow). On the patch matrix, the pulse output shares the
input with the Sample&Hold output use the switch on the Sample&Hold module
to select the output which is routed to the matrix.
FILTER
The FILTER is a resonant multimode filter of unique design. Highpass and
lowpass filters in series allow for designing various filter responses. With
the LPF (lowpass filter cutoff) knob set to 10, the lowpass filter is all the
way open and the filter becomes a highpass filter with the HPF knob
controlling its cutoff frequency. With the HPF (highpass filter cutoff) knob
set to 0, the highpass filter is all the way open and the filter becomes a
lowpass filter with the LPF knob controlling its frequency. Any other HPF and
LPF knob positions will make a bandpass filter with adjustable bandwidth and
center frequency. If control voltage is applied to the Filter Frequency input
on the matrix, the HPF/LPF SWITCH determines which filter cutoff frequency is
altered. In the middle setting, the cutoff of both filters is controlled via
incoming CV. This also means that the center frequency of the bandpass filter
is altered. In the HPF setting, only the highpass filter cutoff is altered and
in the LPF setting, only the lowpass filter cutoff is altered. Incoming CV is
added to the HPF and LPF knob settings. The filter can be modulated at audio
rate and when RESONANCE is set to 7 or more, it becomes an oscillator that
produces a pure sinewave. The LEVEL knob adjusts the amplitude of the audio
signal from the filter before it is sent to the patch matrix.
NOISE GENERATOR
The SYNTRX II has a Zener diode-based NOISE GENERATOR that provides full
spectrum white noise. The Noise Generator is not voltage controlled, but the
COLOUR knob allows for emphasizing low (LOW setting) or high (HIGH setting)
frequencies of the noise spectrum. The LEVEL knob adjusts the amplitude of
noise before it is sent to the matrix mixer. 8

RANDOM
The RANDOM section is essentially a Sample and Hold circuit that generates
stepped control voltages for voltage control of other modules. It has an
independent S&H RATE control as well as an output LEVEL control and two
switches. The FREE/GATE switch selects if the Sample and Hold circuit works
from the internal clock (FREE setting) or from the gate signal (GATE setting),
which means that the voltage on the output will change with each incoming
gate. The OSC3/S&H switch selects which signal is sent to the patch matrix.
The matrix has only 16 inputs, therefore the RANDOM shares its matrix input
with the OSCILLATOR 3 pulse output.
The matrix mixer has a dedicated S&H Input where you can assign any signal for
the S&H circuit. For example, a triangle-sawtooth wave (depending on the
waveform knob setting) from Oscillator 3 will generate staircase-like control
voltages on the output, noise will generate random voltage steps. Experiment
with various inputs and S&H RATE settings! With high S&H RATE settings and an
audio signal applied to the S&H Input, you can achieve an analogue bitchrush
effect.
RINGMODULATOR
The RINGMODULATOR, also known as a Four-Quadrant Multiplier, is a special case
of amplitude modulation – one signal changes the level or “multiplies” the
level of a second signal.
Two signals A and B – are required in order for the ring modulator to
operate (if you multiply by zero, you get zero), for example two oscillators
both running at audio rate or an oscillator and microphone patched into one of
Inputs of the SYNTRX II. Signal A is assignable on the matrix mixer’s Ringmod
A input, while signal B is selected by rotary switch SOURCE B. Depending on
the input signal frequency relationship, the output is a complex set of
component tones, typically metallic, bell-like sounds. When a voice from a
microphone is modulated by an oscillator, a robotic speech effect can be
achieved.
Adjust the LEVEL of the ringmodulator output to your taste.

TRAPEZOID – ENVELOPE GENERATOR AND VOLTAGE CONTROLED AMPLIFIER
The SYNTRX II has a distinct looping envelope generator called TRAPEZOID. It
is functionally similar to the one found on the EMS Synthi, because the
envelope shape is reminiscent of a trapeze. The Trapezoid generates control
voltages to control events on the SYNTRX signal amplitude, pitch of the
oscillators, cutoff frequency of the filter, etc. By default, it is a looping
envelope generator with 4 stages ATTACK, ON, release (DECAY), and OFF.

TIME
All stages are manually adjustable and the decay stage is also voltage controlled, so the decay time of the envelope can be varied automatically if a control voltage is applied to the Decay input on the matrix mixer. If the OFF control is set to more than 9, the looping is terminated and a new envelope cycle can be initiated by pressing the GATE button next to the joystick controller. If the SYNTRX II is used with external CV/Gate signals (connected to CV and Gate inputs correspondingly) or a MIDI keyboard or sequencer, in most cases, the looping must be off (OFF control all way clockwise), otherwise, when the gate will be off, the envelope will start looping. Also with the external gate signal applied, the ON knob will have no effect the ON time is defined by the gate length. The output level of the envelope generator is adjusted by the TRAPEZOID knob, in other words, it sets the modulation depth for other “modules” on the SYNTRX II. Besides the envelope generator, the trapezoid unit has a built-in voltage-controlled amplifier (VCA); its control voltage input is linked to the output of the envelope generator. The audio signal input of the VCA is the Envelope Signal input on the patch matrix and the SIGNAL control in the trapezoid unit sets the audio signal level after the VCA output. The LED gives visual feedback on the envelope generator status
ATTACK time of the envelope generator is 6ms 850ms ON time of the envelope
generator is 0-1,5s DECAY time of the envelope generator is 16ms 2s OFF time

EFFECTS
The SYNTRX II has great-sounding DELAY and REVERBERATION effects, developed in
collaboration with www.112db.com. The switch allows for selecting between the
effects, while the TIME knob adjusts the delay time (5ms (50ms in Tape mode) –
500ms in SHORT mode and 5ms (50ms in Tape mode) – 3″ in LONG mode. You can
change the modes in configuration settings.) for the delay effect or room size
for the reverberation effect. The FEEDBACK knob sets the number of repeats for
the delay effect (it goes into self-oscillation with high feedback settings)
and applies feedback for the reverb. With the feedback knob all the way
clockwise the reverb starts looping and you can use it as a drone source with
adjustable pitch (TIME setting). The LEVEL knob adjusts the volume of the
processed signal. Besides the features above, you can record motion of the
TIME knob – push and hold the REC/CLEAR button and rotate the TIME knob. You
can record up to 8″ of knob motion. To clear this automation, double tap the
REC/CLEAR button. Please note that the automation is not saved in memory.
Also, remember that the EFFECTS unit outputs processed (WET) signal only, so
in order to achieve a dry/wet mix, you have to send both the unprocessed (DRY)
and processed (WET) signals to the same output(s) on the patch matrix. In that
case, the EFFECTS LEVEL knob will control amount of wet signal. An example of
the most basic patch that involves EFFECTS is shown on page 23 of this manual.
OUTPUT FILTER
Both output channels feature an OUTPUT FILTER that is essentially a tone
control. If the control is at 5 on the dial, the frequency response is flat,
turning the control counter-clockwise (towards the LOW setting) boosts lower
frequencies, turning it clockwise (towards the HIGH setting) boosts higher
frequencies. These are manual-only controls. Use the output filter for final
treatment of the outgoing sound for each channel.
OUTPUT AMPLIFIERS
The OUTPUT AMPLIFIER section is for the final treatment of the audio signal
before it is sent to the headphones output and to the main outputs going your
external mixer desk. As there are two output channels (Ch1 output and Ch2
output on the patch matrix) and each channel has stereo panning (PAN) controls
(the manual only control), you can design advanced soundscapes in stereo. The
LEVEL controls allow for setting the output level manually, but there is a
voltage controlled amplifier on each channel so the control voltage from the
patch matrix is added to the manual level settings, thus providing even more
versatility in sound design. When a CV is applied to one of the channels,
while the same but inverted CV is applied to the other channel, a stereo
panning effect is achieved.

JOYSTICK
The JOYSTICK allows for altering two bipolar control voltages simultaneously.
These control voltages can be applied to the control parameters on other
“modules” e.g. Oscillator pitch, Filter cutoff frequency, VCA gain and others.
The X and Y level controls define the range of the control voltages where
maximum range is -5V to +5V. The joystick is connected to pins 15 and 16 on
the patch matrix, and there’s a hidden feature the control voltage from
user-defined MIDI CC messages is added to the Joystick’s voltage. For even
more extensive control over parameters on the instrument, the RECORDING of
joystick movements has been implemented. To record a joystick movement, push
and hold the REC/CLEAR button and move the joystick. You can record up to 8″
of motion. Playback starts half a second after the REC button is released, and
the bicolour LEDs will give visual feedback on the CVs going the output. If
you move the joystick during playback, the recorded CV is overdubbed, and
playback resumes in half a second after no motion is detected. To clear the
recording, double tap the REC/CLEAR button. The Joystick module also features
a manual GATE button that controls the TRAPEZOID generator described above.
You also can record a GATE PATTERN push and hold the REC/CLEAR button and
push the GATE button to record a gate pattern. You can record up to 8″ of gate
patterns. To clear the recording, double tap the REC/CLEAR button.
INPUT 1
The SYNTRX II has two external audio signal inputs and you can use the
instrument as an FX unit for external signal treatment or to inject the
external signal into advanced patches and generate completely new sounds.
INPUT 1 comes with an input LEVEL attenuator and an ENVELOPE FOLLOWER (E.F.).
The envelope follower will do two things: 1) extract a gate from the incoming
signal, 2) extract the envelope or, in other words, control voltage that
follows the change of the amplitude of the incoming signal. The basics of the
envelope follower operation are shown in the image below. The envelope
follower works the best with audio signals that have beats and it has four
controls. The gate THRESHOLD knob sets the threshold (upper level) of gate
detection. A signal below the threshold will be interpreted as a gate and the
LED will turn on to indicate the presence of the gate. The switch TO GATE
sends an extracted gate to the gate ORing circuit, and it’s added to other
incoming gates (one from an external keyboard, internal sequencer or GATE
button). The DECAY knob adjusts the decay time of the envelope at 0 setting
it’s sharp and follows the amplitude of the incoming signal, at more clockwise
settings, the decay time is extended. The EF LEVEL knob is the envelope
follower output CV attenuverter. It determines how much CV is sent to the Env.
Follower output. The Inverted signal (counter clockwise setting of the EF
LEVEL knob) is useful for ducking audio outputs in a beat with a signal
applied to INPUT 1. The INPUT1 is normalled to the SCOPE OUTPUT, so, if
nothing is patched into the INPUT 2 jack socket, a signal from the SCOPE
OUTPUT is automatically routed to INPUT 2. 12

INPUT 2 comes with a gain switch that selects between LINE level signals in
the input and MICROPHONE level signals (this setting is also recommended for
guitar pickups). Select the input amplifier gain and adjust the signal level
with the LEVEL knob. You can also overdrive the signal in the far clockwise
settings of the level controls. The INPUT 2 is DC coupled, which means it can
also process control voltages, and the DIRECT/INVERT switch inverts the
incoming signal. This is particularly handy, if you want to create patches
with stereo panning. See the patch example on the page 22 of this manual.
INPUT 2 is also normalled to the SCOPE OUTPUT, so, if nothing is patched into
the INPUT 2 jack socket, a signal from the SCOPE OUTPUT is automatically
routed to INPUT 2.
SCOPE
The SCOPE is used to monitor both the CV and audio signal levels in the SYNTRX
II patches. The internal signal levels in the SYNTRX are line level, meaning,
normal, unattenuated audio signal that is about 3,7 Vptp, but it can be higher
when several signals are mixed; CV signals can be up to -5V – +5V . Use the
switch to select between CV and audio signal measurement. In the Audio
setting, the measurement starts from the left side of the scale and the full
scale is ~4.5V. In the CV setting, the centre of the scale is 0 and it
indicates both positive and negative voltages. The SCOPE has a dedicated SCOPE
OUTPUT which you can use to get an extra audio or CV signal.

The SYNTRX II has a digitally controlled analogue PATCH MATRIX. It’s a mixer/buffered multiple matrix, so when designing patches, you can mix up to 16 inputs to a single output without loosing signal strength and likewise you can send one signal to up to 16 outputs simultaneously. Moreover, each patch point has three levels of attenuation gain 1, gain 0,7 and gain 0,3 for more advanced patches. The matrix has 16 inputs (or receives, where signals are applied) and 16 outputs (or sends, where signals are sent).

PATCH MATRIX IN USE
The PATCH MATRIX has 256 possible patch points, each with three levels of attenuation and it has a memory of 256 patches.
To build a patch, avigate the matrix via the X and Y encoders and select a
patch point. The left encoder allows you to make attenuated connections. Push
the encoder to make a connection. The first push makes a connection with a
gain value of 1, the second gain 0.7, the third gain 0.3 and the fourth
turns the connection off. The right encoder makes a connection with a gain
value of 1 and pushing it the second time disconnects it basically, it works
like a shortcut with only two options maximum attenuation level or off.
You can also navigate through the matrix via the joystick. To do so, push and
hold the SHIFT button and move the joystick. Push the right encoder to
activate a patch point. In order to draw a patch via the joystick, push and
hold the SHIFT button and the right encoder simultaneously and move the
joystick – the movement path will enable patch points. To clear them, hold
down SHIFT and REC/CLEAR while moving the joystick.
Connection preview/live performance (equivalent to making experimental sounds
on Synthi by sticking a pin into a matrix patch point to check the sound and
removing it) navigate to the desired connection point, push and hold SHIFT
and push either one of the encoders. While the encoder is pushed, the
connection is active.
Saving patches. Once you are happy with a patch, push the SAVE button and
access the saved patches view. Use the X/Y encoders to navigate to the desired
position and push either one of the encoders to save the patch. The relevant
LED on the patch matrix will illuminate. If you change your mind and do not
want to save the patch, just push SAVE or SHIFT to exit to the patch building
mode. The matrix automatically saves the last patch every 30″ and when power
cycling, it will remember the last active patch. You can choose a memory
display between matrix and text modes. Refer to configuration settings on page
26.
Random Patches. Sometimes you may want to go extremely experimental or you may
simply lack inspiration. Therefore we have implemented PATCH > randomization
functionality! Push and hold the SHIFT button and push the right PATTERN
button and the Matrix Mixer will generate a random patch based on
randomization density and randomization area settings described on
configuration settings page in this manual. NB! Not all random patches will
generate sound because sometimes there will be no signal routed to the
output(s).
Sequential patch change. Push < PATCH > buttons to change patches instantly.
With each push of a button, the patch matrix will advance to the next (or
previous) saved patch. This is a very handy feature when designing live
performances with the 16 SYNTRX II.
Recalling patches. Push the RECALL button to access the saved patches mode. Use the encoders to navigate to one of the saved patches, and push either one of the encoders to recall it. Deleting patches. Push the SAVE button. Use the encoders to navigate to the patch you wish to delete. Push and hold RECALL for more than 5″ and the LED with the patch name will go off. Turn the matrix off. At certain conditions the matrix may feed some noise into audio path of the SYNTRX II, therefore during recording session you may want to turn the matrix off. To do so, push and hold the SHIFT button and push the RECALL button. The matrix will go on if you push any button or rotate the encoder.

THE SEQUENCER
The patch matrix on the SYNTRX II can be used as a piano roll sequencer that
allows you to create up to 16 step sequences with notes within a 3 octave
range. The output control voltage of the sequencer is automatically routed to
all three Oscillators.
To activate the sequencer push and hold the SHIFT button and push the GATE/SEQ
button. The piano roll sequencer will replace the patch matrix.
The first 12 rows of the matrix represent SEMINTONES, where the bottom note on
the 12th row is C, while the columns represent the sequencer steps. Use the
X/Y encoders to navigate the matrix and push one of encoders to enter a note.
The first push will initiate a note in the lower octave and the relevant LED
will be 1/3 dimmed. The second push of the encoder will initiate the note in a
middle octave and the relevant LED will be 2/3 dimmed. The third push of the
encoder will initiate the note in the higher octave and the relevant LED will
be fully illuminated. To remove the note, push and hold the SHIFT button and
push the right encoder.
Row 13 on the matrix shows the number of steps in the sequence. In order to
set the LAST STEP of the sequencer, push and hold the SHIFT button and rotate
the X encoder. The default setting is 16 steps.
The bottom three rows set the GATE LENGTH per step. There are 6 discrete gate
lengths, indicated as vertical bars: 15%, 30%, 50%, 65%, 80%, 100% (merge with
the next gate), indicated by the LEDs in two levels of brightness. In order to
set a gate length, push and hold the left encoder and rotate the right
encoder. You can also set a default gate length in the configuration settings.
In order to SET THE BPM of the sequencer, push and hold the SHIFT button and
rotate the Y encoder. The matrix will indicate a BPM.
In order to set a PLAY DIRECTION of the sequencer push and hold the < PATCH
button and rotate the X encoder. The matrix will indicate play directions:
forward (FWD), backward (BWD), ping-pong (PP) and random (RND).
You can select a CLOCK SOURCE of the sequencer in Global settings. But by
pushing and holding the < PATCH button and rotating the Y encoder, you can
initiate the manual step advance (MAN). In this mode you can use PATCH >
button to navigate through the steps in a sequence.
START and STOP the sequencer by pushing the PATCH > button. Reset the
sequencer by pushing and holding SHIFT button and pushing PATCH > button.
When the sequencer is stopped, you may want to reset the current note to 0V on
the 1V/oct input of the Oscillators. To do so, push and hold the SHIFT button
and push the RECALL button.
The sequence is saved with the current patch on the matrix mixer.

THE STEPPED MODULATION SOURCE
As mentioned above, the sequencer has a hidden feature two stepped
modulation sources; a CV from these is added to the joystick. This allows you
to assign controlled, stepped modulations to any destination on the SYNTRX II
via the patch matrix and offset/transpose them with the joystick.
When in SEQUENCER MODE, push and hold the SHIFT button and push the Y ENCODER.
The Y axis modulation setup screen (indicated by the LED dot in the bottom
left corner of the matrix) will appear. Unlike the sequencer, the modulation
sources are bipolar, and they generate discrete, 21 step (indicated by 7 LED
bars, where each point has 3 brightness levels) voltages with a maximum
amplitude of +/-5V. Use the X and Y encoders to navigate the matrix and design
the modulation pattern (see the example to the right). Note that the top LED
on each bar has 3 brightness levels this indicates three sub-levels of the
CV on each step.
The second SHIFT + Y ENCODER push will get you into the X axis modulation
setup screen, indicated by the LED dot in the bottom right corner of the
matrix.
Please note that you can attenuate these modulation sources with the LEVEL
potentiometers on the joystick.
The step count and a play direction of the stepped modulation sources is
automatically aligned with the sequencer. On the example to the right, you can
see a 12-step modulation pattern designed for the Y encoder.
The sequence along with the X/Y modulation settings is saved with the
currently loaded patch on the matrix mixer. If you want the sequencer to start
running when the patch is changed, leave it running before saving the patch.
If you wish to start it manually, stop the sequencer before saving the patch.
In order to EXIT the sequencer screen, push and hold the SHIFT button and push
the GATE/SEQ button.

BUILDING PATCHES
Building patches on the patch matrix requires a non-linear approach that is bit different form patching a regular synthesizer. Without a patch designed, the SYNTRX II will not make any sound. When connecting the modules, you basically go in circles in and out of the patch matrix. Here are some examples.

sawtooth wave, the pulse width of Oscillator 1 signal is modulated by the
horizontal movement of the Joystick, and the pitch of the Oscillator 1 will be
modulated by the vertical movement of the Joystick. Set the Joystick signal
levels to desired amount and enjoy modulation madness!

This is an example of the patch that provides stereo panning effect. The pulse
wave signal from the Oscillator 1 goes to both Output Channel 1 and Output
Channel 2. Make sure, both LEVEL knobs on the Output Amplifiers are set to
desired volume and the Channel 1 is panned all way left, while the Channel 2
is panned all way right.
Now, we are sending triangle wave of the Oscillator 3 to the SCOPE Output and
to the Output level of the Channel 1. Because the Scope Output is normalled to
Input 2, the signal from the Oscillator 3 is automatically applied to the
Input2.
Set the Input 2 gain to LINE and INVERT the signal. Then send the inverted
signal to Output level of Channel 2. Now, the volume of the channel 1 is
changing, depending on the frequency of the Oscillator 3 and the volume of
channel 2 is changing with inverted signal of the Oscillator 3. Adjust
Oscillator 3 triangle signal level and the Input 2 signal level in order to
achieve desired depth of panning.

The SYNTRX II has basic MIDI implementation you can select a MIDI channel on
which the SYNTRX II receives MIDI note, note on (gate), pitch wheel,
modulation wheel (assigned to the VCF cutoff) messages, as well as two
configurable CC messages and a note velocity message that is assigned to the
VCF cutoff. The SYNTRX II receives only one MIDI note at a time, and it is
higher note priority.
If no external CV is patched into the relevant inputs, MIDI note messages
control the pitch of the VCOs, if external CV is used, MIDI notes are added to
the external analogue CV, so you can use the MIDI keyboard or sequencer to
transpose the pitch of the VCOs.
MIDI CC messages are added to the joystick X and Y control voltages
correspondingly, so you can address them via same patch matrix connection
points as the joystick. MIDI CC message assignement is described in the
CONFIGURATION SETTINGS section on this manual.
You can send MIDI panic message by pushing and holding SHIFT button and
pushing REC/CLEAR button for 3 seconds.

CONFIGURATION SETTINGS
All configuration settings on the SYNTRX II are done via the patch matrix. In order to access the configuration settings, push and hold the SHIFT button and push the < PATCH button. The configuration setting screen will appear. There are two kinds of configuration settings per-patch and global ones.
Per-patch settings are saved with the individual patches, while global
settings are applied to all patches.
Use the left (Y) encoder to navigate through the configuration setting menu
pages and the right encoder (X) to alter the settings. A LED dot in the far-
right column indicates the page you are in. Every setting starts with an info
screen that turns into a running line with the name of the setting, on the
bottom part of the screen you can see the configuration options.
The patch-relevant settings (per-patch settings) come first, and they are:
FX MODE. The delay and reverb effects can be set to TAPE or BBD mode. The
screen (see the example to the right) shows FX BD (running line – FX BBD) and
the options are OFF and ON. If you select ON, the BBD mode is activated.
FEEDBACK ON THE REVERB. Instead of the default tone adjustment on the
reverberation effect, you can have a feedback adjustment. At the maximum
clockwise setting of the FEEDBACK knob, the reverb will work as a sampler that
samples a certain amount of audio depending on the TIME setting and will loop
it. The screen shows REV F (running line – REVERB FEEDBACK) and the options
are OFF and ON. If you select ON, the feedback mode on the reverb is
activated.
DELAY TIME setting. The matrix shows DELL (running line – DELAY LENGTH). You
can choose between SHORT and LONG modes.
PORTAMENTO TIME. The matrix shows P-TM (running line – PORTAMENTO TIME). Sets
a default portamento time on the internal sequencer and/or MIDI in discrete
steps from 0 to 100, where 100 corresponds to 1″ of portamento time.
The global settings are:
DEFAULT GATE LENGTH OF THE SEQUENCER allows you to set the default gate length
of the built-in sequencer. The screen shows SQGL (running line SEQ GATE
LENGTH). The gate length has discrete settings and the available options are
15%, 30%, 50%, 65%, 80%, 100%.
PATCH RANDOMIZATION DENSITY sets the density of the connection points when
randomizing patches. The screen shows RNDD (running line RANDOM DENSITY),
and you can set randomization density from 0-80%.
PATCH RANDOMIZATION AREA sets the area on the matrix, where the randomization takes place. The screen shows RNDA (running line RANDOM AREA), and you can push the right encoder to set the randomization area. As soon you push the right encoder, a setup screen appears. There are three steps in the randomization area setting. First, you will see a brighter dot in the top left corner of the area and you can use encoders to adjust the top size of the area; once done, click the right encoder and the brighter dot will move to the bottom right corner, and you can adjust the area from the bottom right corner. Once happy with the size of an area, click the right encoder again and you can move the randomization area across the matrix. Click the right encoder to exit to the main menu.

octave switch to -3, the Tune knob to 5 and connect a chromatic tuner to the
SCOPE OUTPUT and connect the OUTPUT 1 to a mixing console or a speaker. Now,
push the right encoder and the SYNTRX will advance to calibration mode. The
screen will show C0. Adjust the Tune knob to read C0 on the tuner. Now, rotate
the left encoder, and the screen will show C1. If the tuner does not read
exactly C1, rotate the right encoder until the tuner reads exactly C1, rotate
the left encoder again and adjust the right encoder until tuner reads exactly
C2. Proceed the same way till you adjust the C8. Once done, push the right
encoder to exit the calibration screen.
MATRIX DIMMING allows you slightly dim the entire matrix if you find the
default setting too bright. The screen shows MX D (running line MATRIX DIM)
and you can turn it ON or OFF.

VERSION). This screen indicates the current firmware version.
FACTORY RESET. The screen shows FRST (running line – FACTORY RESET). In order
to perform a factory reset push the right encoder and the firmware update
screen will appear. If you change your mind, push the left encoder (noted by
the X in the bottom left corner); if you want to proceed with the FW update
push and hold the right encoder (noted by V in bottom right corner). This will
initiate countdown to the factory reset. Keep holding the encoder until reset
is completed. NB! The factory reset will delete all your patches.
Firmware update
The firmware update is performed via MIDI sysex. Download the sysex file from
the SYNTRX II page on www.ericasynths.lv. Power the SYNTRX II off, connect it
to the MIDI interface and open a sysex tool (for example, MIDI-OX for PC and
SysEx Librarian for Mac) on your PC or Mac. Now, push and hold both the
REC/CLEAR and GATE/SEQ buttons and power the SYNTRX on. The matrix will show a
firmware update screen. Send the firmware file via the sysex tool and the
matrix will indicate the status of the firmware update. It typically takes
couple of minutes to complete the update. Once done, restart the SYNTRX II and
your new firmware will be installed!
