SM010 MATRIXARCHATE: USER'S GUIDE

FIRMWARE VERSION 1.3

Thank you for purchasing an SSSR Labs module! We wish you a long and fruitful experience with this

module. On pages of this manual, we will explain how to use the SM010 MATRIXARCHATE.

The MATRIXARCHATE module is a 16x8 input-output sequential matrix signal router capable to establish

digitally controlled electrical connections between various signal sources and destinations and store

those settings into up to 60 user programs. A set of individually picked programs may also be

sequentially recalled by an external clock.

Warning!

Do not connect the unit to a modular system having 15-volt power lines. This unit was not tested for

proper operation with 15-volt systems and there is a possibility of overheating and further damaging

certain components of the unit.

Do not connect any voltage or current sources that are not intended to be used as musical instrument

sound or voltage control outputs to the unit's inputs/outputs! Connecting low-impedance current

sources such as power sources of any kind can cause immediate damage to the unit.

Although MATRIXARCHATE can stand voltages above +10V or below -5V, it's not recommended to

intensely use such kind of signal sources, and under no circumstances, they may have output impedance

lower than 100 Ohms

Not observing the above instructions cancels the warranty!

CONNECTING THE UNIT

The unit is equipped with a 10 to 16-lead Eurorack power cable. The unit has a keyed power connector

that prevents the unit from the power connector being plugged in wrong. However when using a 3rd

party power cable or non-keyed power busses, please make sure that the -12v line is physically

connected to pins 1-2 (below), marked with the ЯED STЯIPE label.

THEORY OF OPERATION

The MATRIXARCHATE router is based on a matrix of 128 digitally addressed analog CMOS cross-point

switches. In further reading it will be referred as Switch Matrix.

NERD INFO. The switch matrix essentially works very similar to array of passive multiple

modules or a switches on a grid of wires. Each switch is bi-directional and bi-polar with "On"

resistance of approximately 65 Ohms. The "Off" resistance is comparable to a disconnected

mechanical switch. This means that it has no inputs or outputs in its usual meaning.

The switch matrix is updated each time when the state of a certain switch has been toggled by a user, or

when a program is recalled. Any switch is constantly accessible in real time right from the front panel,

without any so-called menu diving.

The switches are addressed as ROWS labeled by numbers and COLUMNS labeled by letters, exactly as in

the good old Battleship game. For ease of understanding we can sometimes describe row jacks as

inputs, and column jacks as outputs but the actual direction of the signal can be arbitrary and even both

ways at the same time. Why is it made so? Because design of this module is optimized for pitch-accurate

CV distribution and fast patching between different CV sources and synthesizer voices, and the I/O

configuration allows using larger number of modulation sources with fewer destinations, or vice versa,

the using a small set of controls with a complex setup.

MODULE INTERFACE

The module has six modes of direct operation: Operative, Saving, Setup, Background Sequencing, Quick

Recall and Silent. It also can be remotely controlled using MoNoMe Teletype.

There are three sets of buttons: Rows, labeled 1to 16, Columns labeled by letters Ato Hand Utility

buttons PREV, SAVE, NEXT and SETUP.

The functions of buttons depend on the current mode of operation and its respective context. You can see

a number of different labels next to the utility buttons. The PRIMARY function, the SECONDARY function

and the [TERTIARY] function. These functions are accessed by pressing a utility button while holding a

Modifier, similarly to holding Shift or Alt key on a computer keyboard. Buttons Band Dare labeled as

function modifiers for the utility buttons: the secondary function f1 and the tertiary function f2. So, when

two buttons are mentioned — the modifier followed by the utility button — the combination is implied: for

example f1-SAVE. The combination of row and column buttons will be always referenced with the

number followed by a letter, therefore 1-Fis a combination of row button 1and column button F, and f1

is the name of the modifier.

FRONT PANEL CONTROLS

Let's take a look at the front panel. It consists of the following controls:

1. Ports 1...16. These 16 ports are associated with ROWS of the matrix and usually may be considered

inputs. Four of these ports are normalled to other signals, which means that when there is no plugs

inserted into corresponding jacks, these rows are connected to certain internal voltage sources and

signals. Row 13: 0 V ground, Row 14: +5 V source, Row 15: STEP input, Row 16: RESET input.

2. Ports A...H. These 8 ports are associated with COLUMNS of the matrix.

3. Sequencer STEP input. This logical input is used to advance to the next program in a sequence by the

input trigger. The threshold voltage is at about 0.7 V.

4. Sequencer RESET input. This logical input is used to rest to the ﬁrst program of the sequence by the

input trigger. The threshold voltage is also at about 0.7 V.

5. 8×16 dots PATCH Display. It shows the current state of the switch matrix or other information.

6. 2-digit 7-segment PROGRAM Display. It shows the number of the currently selected program.

7. Row selection buttons 1...16.

8. Column selection buttons A...H.

9. Program utility buttons: PREV, SAVE, NEXT. These buttons are used for switching between programs

and other program-related manipulations.

10. SETUP/EXIT utility button. This button toggles the Setup Mode, cancels come operations and does

other useful functions.

OPERATIONAL MODE

When you turn on your system, Matrixarchate enters the main mode called operational. In this mode the

PATCH display shows the active connections. The combination of row and column button toggles the

state of the switch at the point of intersection of the respective row and column. This is the only type of

combination in which order of button presses is not important. For example, to connect or disconnect

input 1with output A, you press buttons 1and Aat once. The dot located in the cross point between

those row and column will indicate the state of the corresponding switch.

N91090909090909090

The PROGRAM display shows the number of currently loaded program. You can navigate through

programs by pressing the PREV and NEXT utility buttons. To advance 10 programs up or down press f1-

NEXT or f1-PREV. There is another method of navigation called Quick Recall Mode. It will be described

later.

The combination f2-NEXT instantly generates a random patch. The random patch always has exactly 8

connections: 1 row per column with no collisions.

N91096098090909309090

N90909092095090940980

Below the SETUP button you can see the blue label CLEAR, which means that pressing f1-SETUP clears

the switch matrix.

N9090909090909090

MATRIXARCHATE: User's guide. page 6 of 17

CREATING A PATCH PROGRAM

Let's make a working program.

Clear the current patch by pressing f1-SETUP.

In the following example we have 4 modules connected to Matrixarchate: a MIDI to CV converter,

Kotelnikov wavetable voice module, a VCF and a second ADSR envelope generator.

Let's add some sources to module's rows in the following order:

1. Keyboard CV;

2. keyboard gate;

3. Kotelnikov's Transient Generator's output;

4. Another EG's output

Then we add some destinations at columns:

A. Kotelnikov's V/Oct input

B. Transient generator's trigger input

C. Amplitude modulation input

D. Waveform index modulation input

E. Second EG, trigger input

F. VCF cut-off frequency input

Now we interconnect this set a usual way by enabling the switches at the intersection points: Pitch CV to

V/Oct, Gate to TG's input, and TG's output to AM and WM simultaneously. Also, we connect the gate to

the secondary ADSR module, and control the cut-off frequency with that. This patch works as we may

expect: Notes change the oscillator's pitch, key presses start the envelope generators, one of which

shapes the loudness and the timbre, and other one shapes the cut-off frequency.

PASSIVE CONNECTIONS CONSIDERATIONS

Here we should understand two things. As soon as a row is connected with the column, they form a

NODE, and any additional connection with the same column or row will join this common node. And a

node shall not be confused with a mixing stage, logical 'AND' or a dedicated isolated connection. It's just

a straight electric node tying all the endpoints together. So, you will get a predictable result only

connecting ONE source to one or multiple destinations. When you connect multiple sources together,

the signals will not be added. Instead their currents will be added and you will get a mean value of their

voltages and only if the source output impedances are close to each other. The Doepfer standard

suggests 1 kΩ output impedance but some modules may have significantly lower impedance such as 220

Ohms or even 100 Ohms, so their signal will dominate over others.

Also, you may think: OK, I have two trigger outputs, and a sensitive logical module, so even at the half of

the logical one's level it will be triggered, so I can make a logical OR, interconnecting multiple sources in

the same node. Most of the time it is so but if some logical module have an open collector going directly

to the output jack, it will literally tie this line to ground on the logical zero's state, so everything

connected to the line will be grounded as well. However we will further assume that a full standard

compliant modules with 1 kΩ output impedance are used.

Example / Nerd Info:

Input 1: Vout1=5 V, Rout1=1 kΩ

Input 2: Vout2=8 V, Rout2=1 kΩ

Average signal = (5+8)/2 = 6.5 V

Input 1: Vout1=4 V, Rout1 = 100 Ω

Input 2: Vout2=8 V, Rout2 = 1 kΩ

Average signal = 4+((8-4)*100/(1000+100)) = 4

Please keep these considerations in mind when planning your patch.

Let's assume that in our example we want to also control the cut-off frequency with the pitch CV. Make

an additional connection at 1-F:

N91092093093092094109090

N9090909090909090

The correct note tracking is gone and envelope now modulates the pitch. Why is it so? Because we just

joined Row 1 with Row 4 via Column F. And also, we joined Column A and Column F via Row 1, so we

have a common node joining together pitch CV, envelope's output, V/Oct input of the Kotelnikov module,

and also the VCF's input. If we untie envelope from the pitch CV, the pitch tracking will get back to

normal operation. Of course, you may experiment with tying many lines together and sometimes get

interesting results, but first you need to learn how to make predictable patches.

SAVING MODE

The unit has two memory areas: a non-volatile memory used to store programs and settings, and a

temporary operative memory, in which all programs and settings are copied after powering on the

module. All editing is performed in operative memory.

To permanently store the changes you need to save your patch.

Enter the saving mode by pressing the SAVE button.

Now, if you press SAVEone more time, the active patch will be saved to the current program, overwriting

its initial contents. You can also save or copy this patch to another location, pressing the PREV/NEXT

buttons, or, if you changed your mind, you can exit the saving mode by pressing the SETUP button. Hence

the full name of this button: SETUP/EXIT. The interesting feature of Matrixarchate is that all modified

and yet unsaved programs are kept in the operative memory, so even if you switch to another program

and later get back to the modified one, all changes still will stay there until module is powered off. You

can revert current program to the last saved state by pressing f1-SAVE in the operational mode.

SETUP MODE

Upon pressing the SETUP button in the operational mode, you enter the SETUP mode, indicated with two

dashes (--) on the program display. The meaning of the PATCH display is now different. The top part is

dedicated for programming the sequencer list. Please refer to the section SEQUENCER for more

detailed explanations. The lower part indicates current global settings of the module and sequencer.
