FEATURES
4 independent channels with bipolar CV / Gate outputs and
Clock Input that allow all things random.
Each channel can be set to generate either continuous
Voltages, Envelopes or as a Quantizer.
Mutes and Holds per channel
3 States per channel allow very fast settings changes,
allowing from smooth to drastic transitions.
Controls over Voltage Range, Quantization with custom
scales, Probability, Distribution curves and Smoothing, plus
time and bpm ranges, time distribution curves and several
clock sources.
A 32 step sequencer per channel that can work completely
independent or in sync.
8 Assignable CV inputs and 4 Gate inputs can be internally
mapped to any setting of any channel.
3 configurable Logic outputs allows complex logic events
comparing different channel states.
Average CV output of all 4 CV outputs.
Easy VCO tuning available in the Menu.
Calibration and mapping of all 4 CV outputs is also allowed
throught the Menu
At ADDAC System we love all sources of unpredictability be it by randomness or signal complexity.
This module greatly expands on the principles of our ADDAC501 Complex Random from 2013.
This is a fully fledged 4 channel voltage generator capable of all things random, with quantization,
probability, distribution, interpolation, time control, clock, states and a 32 step sequencer.
The module operation relies on its screen for all parameter editing, each button accesses one single
page where parameters can be changed allowing a fast and fluid workflow across all settings.
Long presses on all buttons have a secondary function allowing fast Channel selection plus Mute and
Hold functions.
The combination of having 2 Encoders with Push buttons allow swift navigation and editing across all
pages and their settings.

LONG PRESSES
PASTE, RANDOM & RESET
The 3 State buttons have a secondary function when
pressed for longer than 1 second.
STATE A - PASTE
A long press on this button enters the Copy screen.
The Copy function is screen dependent meaning that will
copy different settings depending on the screen state.
It is also Channel and State dependent meaning every
State of every Channel can be accessed as a block to be
copied from.
If the screen is in Main then Copy will change all setting
on the current Channel and State from the selection made
on the Copy screen.
If the screen is in any other page, the copy function will
only copy the settings of that particular page.
The Copy screen shows:
The current Channel and State
The current Screen page
The Channel from which to copy
The State from which to copy related to the channel
selected above.
The two Encoders buttons choose between Cancel to exit
the copy screen without making changes and Enter to
execute the copy process.
STATE B - RANDOM
Randomizes the current screen settings to all new random
values, only on the currently selected channel.
If used in the Main Screen it will randomize only the
settings available on the Main Screen.
STATE C - RESET
Resets the current screen settings to the loaded preset
settings and only on the currently selected channel.
If used in the Main Screen it will reset all of the selected
channel’s settings.
ADDAC511 User’s Guide
page 9ADDAC SYSTEM
STATES
Every channel has 3 States, every State is independent
and can have completely diferent settings.
Think of them as instantly accessible channel presets.
They can be used to create drastic or slight changes to a
CV output.
State changes are immediate, once engaged the new
settings take control.
They can be assigned to a CV input, the incoming voltage
level will trigger the corresponding state:
STATE A < 1.6v
STATE B > 1.6v & < 3.3v
STATE C > 3.3v
STATES PROBABILITY
States can also be configured to automatically change, at
every clock cycle, according to probability settings.
To enter this screen users can double click on any State
button.
Configuring the ammount of probability for each state
allows to fine tune the preponderancy of each channel.
Encoder 1 configures the threshold point between State A
and State B while Encoder 2 configures the point between
State B and State C.
Once engaged the States will be changing automatically,
if the user presses a State button it will momentarily
change to the selected state until the next clock cycle
triggers the new state probability and eventually change
the state once again.
States Probability activity is suspended everytime the user
exits the main screen to enter any other screen, it’s
important to suspend the activity to be able to edit the
parameter of the current state without jumping to another
state while in the editing process.

APPLY TO
Here’s a few graphical examples of the Voltage and Gate Out [PROBABILITY] settings.
Notice how they can be dependent or independent.
When [APPLY TO] is set to CV+GATE the Gate only outputs
when the probability is true.
Applying the probability only to CV leaves the Gate intact,
outputting every clock tick. This makes the Voltage Probabili-
ty independent from the Gate Probability.

These screens set the probability distribution for each random
generation made in the time and voltage domain.
Every new random value by default is generated using a
principle of uniform distribution (equal probability for all
possibilities) however these can be weighted, meaning that
they can be defined to make a certain range area more
predominant, while always keeping the result within the
voltage range defined in the [VOLTAGE] screen.
The weighted generation may follow three types of probabilis-
tic distributions: uniform distribution, a slightly modified normal
distribution and walk/drunk distribution (walk mode).
Uniform distribution (OFF), as mentioned above, has no weight,
any value within the defined range has equal probability of
being selected.
Normal distribution (FREE) is bell shaped, it can be described by
its mean value and a deviation around that value defined by
[POSITION]. Most random values will be around this position
with more or less deviation depending on the [SPREAD] value. In
our modified version of the normal distribution, if the calculated
value is outside the selected voltage range, it is brought back
inside the range.
Walk (WALK), like uniform distribution has equal probability for
all possible values but restrains it’s range within a proximity to
the previous value, resulting in a plot similar to the stock
market as an example.
The probabilistic distribution is further influenced by the
linearity parameter, which tilts the probability distribution either
towards the lower or higher ranges.
MODES
The CV out value will have different probability characteristics,
depending on the mode setting:
1. OFF
Uniform distribution (equal probability for all CV values)
2. FREE
Normal distribution, folding back at the upper and lower limits,
parameters:
POSITION - Central value of probability distribution (mean)
SPREAD - Allowed deviation relative to the position (deviation)
3. WALK
The next value has a maximum deviation from the last value,
parameters:
SPREAD - Allowed deviation relative to the last CV out value
LINEARITY
This parameter is independent of the mode selected, it further
weights the probability distribution to give preference to lower
or higher values, as if tilting the distribution.

will also affect the other parameter, one pushes the other
to keep the same range.
In Time Mode the clock is defined in milliseconds, the step length will be randomized from the interval defined by
the Time Min & Time Max parameters.
Setting the Time Minimum higher than Time Maximum will result in a steady clock at a fixed rate without any
randomization.

TIME SETTINGS : BPM MODE
In BPM Mode the clock works as a standard BPM clock, the step length will be randomized from the intervals
defined in the Distribution screen.
The SYNC slot output division is variable, it outputs the required time until the next beat. This will make sure the
next step falls back on the beat. This is especially usefull when using odd time divisions as it resets any offset,
you can see a graphical example below.
BPM DISTRIBUTION SCREEN
In BPM Mode the user can set up to a total of 11
divisions, any division from 32/1 to 1/32 is possible, all
odd combinations included.
A second parameter visualised as a white bar sets the

Sync Channels
Channels can be sync’ed to other channels using the
[CLOCK SOURCE] setting in the [CLOCK] screen.
By default every channel is a Master channel, indepen-
dent from all others.
To change any channel to Slave the user just needs to
select to any other channel in the [CLOCK SOURCE]
parameter, this will make that channel follow the
selected clock.
When set to Slave the [TIME] and [DISTRIBUTION]
screens will then be used to set the parameters for a
new function: Clock Delays. When active [CLOCK
DELAY] will use the slave channel’s [TIME] and
[DISTRIBUTION] parameters to generate a delay value
that will be added to the clock tick, efectively delay-
ing the incoming clock.
This delay can be steady or random depending on the
[TIME] and [DISTRIBUTION] settings selected.

Sync Channels: BPM Mode
The best practice to sync channels is to choose one to be
the master channel setting its [CLK SOURCE] to
[INTERNAL]. The remaining channels can then refer to this
master channel.
In this example Channel 1 is set as [INTERNAL]
Channel 1 [TIME MODE] is set to BPM
The [TIME MODE] setting is very important here as it will
show different options if set to [BPM] or [TIME].
Channel 2 [CLK SOURCE] is set to sync to Channel 1
FOLLOW
Follow will determine the sync mode.
The slave channel can sync to:
[CH BPM] the virtual grid of the master channel BPM
[CH OUT] the real-time gate output.
This would be the Channel 1 real-time Gate Output.
This output will depend on all other parameters on
Channel 1, for simplicity in the example above it’s
randomizing whole and half notes.
[MULT / DIV]
When [USE TIME] is Off, the virtual BPM can be:
. Multiplied (x1, x2, x3, x4, x5, x6, x7, x8, x16, x32)
. Divided (/2, /3, /4, /5, /6, /7, /8, /16, /32)
This would be the Channel 1 virtual BPM.
Virtual here means this is not the Channel 1 real output
but instead the BPM grid to which channel 1 is syncing
to. Channel 2 will then follow this virtual grid depending
of the [USE TIME] and [MULT/DIV] settings.
[MULT / DIV]
When [USE TIME] is Off, the virtual BPM can be:
. Multiplied (x1, x2, x3, x4, x5, x6, x7, x8, x16, x32)
. Divided (/2, /3, /4, /5, /6, /7, /8, /16, /32)

CLOCK DELAY: BPM
ADDAC511 User’s Guide
Sync Channels: Slave TIME MODE = BPM
[CLOCK DELAY]
The [CLOCK DELAY] parameter is used to cause deviation/delay to the incoming clock timing.
In this case the Channel 2 [TIME MODE] setting is very important as it will behave differently if set
to [BPM] or [TIME].
When using BPM the engine will use the time divisions set on the [TIME DISTRIBUTION] screen and
generate a new interval from the divisions pool always using the Channel 1 BPM as reference
ignoring the channel’s own BPM setting.
[CLOCK DELAY] = ON & CHANNEL TIME MODE = BPM
In this example Channel 2 [TIME MODE] is set to [BPM]
FOLLOW
Follow will then determine the sync mode.
The slave channel can sync to:
[CH BPM] the virtual grid of the master channel BPM
[CH OUT] the real-time gate output.
When [USE TIME] is On there is no [MULT/DIV] option.
This will create a delay to every incoming clock, the
delay length is randomized from the [TIME DIVISIONS]
pool. Time divisions longer than the incoming clock are
canceled by the next incoming clock and will not
output.
This will generate a consecutive stream of notes which
lengths are randomized from the [TIME DIVISIONS] pool.
As the current note reaches its final length a new note
is imediatelly generated.

CLOCK DELAY: TIME
ADDAC511 User’s Guide
Sync Channels: Slave TIME MODE = TIME
When using [TIME MODE] set to [TIME] the engine will simply add a delay to the incoming clock source.
This setting is usefull used for generating time based delays, fixed or random, in this case although it is being
triggered by the master channel BPM grid the delays are set in seconds and will most probabbly fall out of the grid
creating odd delays.
The delay time is randomized from the range defined by the [TIME MIN] [TIME MAX] settings in the [TIME] screen.
Delay times longer than the incoming clock are canceled by the next incoming clock and will not output.
In this example Channel 2 [TIME MODE] is set to [TIME]
Keep in mind that Channel 1 [TIME MODE] is still set to
[BPM].
FOLLOW
Follow will then determine the sync mode.
The slave channel can sync to:

LOCK : STATE
ADDAC511 User’s Guide
The channel’s internal generation and lock feature are not active at the same time, although the internal generation can
influence and write values into the lock sequence. For this there are 3 Lock States:
TRACK
When in Track mode the lock sequence is disabled and not editable. The internal generation is active and continuously
stores its output into the lock sequence active steps in a loop.
As an example, if Steps are set to 8 then it will iterate over these 8 steps storing the new value over the oldest step.
HOLD
In Hold mode the sequence is locked, not playing but still editable.
The channel internal generation is active
As an example, if you have a sequence you don’t want to erase but want to use the internal generation for a transition
the Hold mode will keep your sequence safe.
ON
In ON mode the sequencer takes over, the internal generation is disabled unless special changes (Change Once /
Change Allways) are programmed, the sequence can be played and edited in real-time.
GATE:
The Gate can be set to either On or OFF
Step Voltage:
The step voltage can be set in Volts (ex. 2v) or Notes (ex. C2)
+ Cents, the Cents parameter allows for step microtunning.
Step Time:
Unlike a conventional sequencer each step can have different
lengths, this can be set in milliseconds or as a time division
depending if the [TIME] is set to time or BPM.
This allows programming complex phrases where any time
division can be set, ex. 1/16, 1/9 and 15/1 and where each
step can have its own BPM.
Step Probability:
Sets the probability for the step to be outputted, if the
probability is false then the sequencer will hold the last step
voltage for the time defined in the current not outputted step.

chords or totally independent with different scales for each channels.
Changing the quantizer [SOURCE] to any other option than the channel’s own input will render the channel’s [VOLT-

QUANTIZER ROUNDING & NOTE PROBABILITY
Bellow you can find graphical examples with all 3 quantizer rounding standards as well as the note
probability method
ADDAC511 User’s Guide
QUANTIZER
STANDARD QUANTIZER ROUNDING
Quantizer set to octaves of C and voltage range restricted to 2V
The incoming voltage in this case will be quantized to C Octaves, meaning the
output will be a multiple of 1v (0v, 1v, 2v, 3v, 4v)
If a voltage of 1.2v is detected then:
Closest note above will be: 2v
Nearest note will be: 1v
Closest note below will be: 1v
If a voltage of 1.7v is detected then:
Closest note above will be: 2v
Nearest note will be: 2v
Closest note below will be: 1v
Note Probability rounding will force quantization to a set of note defined probabilities.
The incoming voltage only defines the octave output, the probability outcome will set the note.
The note in this case can be furthest from the incoming voltage.
Notes not present in the selected scale appear checkered.
If a voltage of 1.2v is detected then:
The output will be any note in the Major C scale in the octave between 1v and 2v.

LOGIC ASSIGNMENTS
There are 3 Logic Outputs, pressing the [CV & LOGIC]
button iterates throught the each Logic screen, you can
see the selected Logic on the top left corner of the screen.
Logic operations compare 2 variables and output a true or
false statement. Think of it as a gate output where true
will output +5V, false outputs 0V.
The user can configure these operations with any of the CV
inputs, Clock Inputs, CV outputs or Logic outputs.
So it can be used to process External sources as well as
internal sources.
When CV sources are used the logic threshold is 2.5v,
crossing the threshold while rising or falling triggers the
logic comparison.
Besides Logic operations these outputs can also be
configured as counters or clock outputs.
To assign them just enter the Logic Assignment Screen,
select the channel page, press the right encoder to
ADD a new assign:
OPERATION
The Operation to be performed:
NOT, AND, NAND, OR, NOR, XOR, XNOR, COUNTER, CLOCK
OUTPUT
CHANGE
Change defines which variable triggers the logic
comparison: ON X ONLY, ON X & Y
VARIABLE X
The source to be used for Input X
VARIABLE Y
The source to be used for Input Y
In this screen rotating the Left encoder chooses the
parameter to edit, rotating the Right Encoder edits the
parameter value.
Once configured pressing the ADD button [ENCODER B]
saves the settings and will display the assign as a new
line in the main Logic Assignments screen
The output is the result of all lines added.
TRUTH TABLE
Adding more than one line allows for more complex Logic
operations. When setting a second line choosing OP1
(Operation 1) uses the result from the first operation as an
input for the second operation.

VCO TUNING
This is a utility feature which allows to easily tune VCOs when
you’re using the 511 as a 1v/oct generator.
It will override the main program and force all outputs to the
same voltage defined as a musical note.
Octave (0 to 4): raises the voltage in intervals of 1v
Note (C to B): raises the voltage in semitones
A voltage output monitor and keyboard monitors the parame-
ters selected.
CALIBRATE CV OUTS
This screen allows to easily calibrate the 1v per octave
standard.
OFFSET: This value offsets the whole CV output in very fine
intervals of ~0,00076v
GAIN: Amplify or attenuate the 1v/oct scaling
CANCEL: Exits the screen without saving.
RESET: resets calibration to the factory values.
SAVE: Saves and exits the screen.
