You are then back 1n SEQUENCE MODE MULTIPLIER MODE MULTIPLIER MODE 1S where you program the clock divider for odd or longer than 32 step sequencers It 1S somewhat cryptic but 1s easy to understand once you ve used it To enter MULTIPLIER MODE from SEQUENCE MODE you press and hold the STEP MULT button until the EDIT MODE indicator begins to blink Your cursor for the Step and Input displays become inverted when in MULTIPLIER MODE That 1S your cursor 1S now the LED that 1s NOT lit To program the division you have to do some basic math Division Step Display x Input Display x DIVIDE Control For example if you were using 64 step sequencers you could choose 8 x 1 x 8 because 8 x 8 64 you would then while in MULTIPLIER MODE set the STEP control to 8 the SOURCE control to 1 and the DIVIDE control to 8 Note that for the SOURCE control the corresponding Input Display integer 1s relative to the character s position in the Alphabet That is SO 1n the example you would set the SOURCE control to A The result 1S written as soon as you enter MULTIPLIER MODE There 1s no need to push a button to write it to memory Programming a Pattern Programming Steps in EDIT MODE All step programming 1s done in EDIT MODE The SOURCE and STEP controls are rotated to select the Input Source and step you wish to edit A step 1S written to the presently selected Input Source by pressing the EDIT ENTER button quick

4. get started 1 Set your sequencers and seqSQUARED up so they are both clocking off of the same clock source You should see the CLOCK IN indicator on SeEqSQUARED blinking with each clock pulse If this light is not blinking your clock source 1s not working 2 Plug one sequencer s Gate and CV outputs into one of seqSQUARED s in put channels ie channel A 3 Repeat with a new channel for your other sequencer s 4 Turn the DIVIDE control to set to your shortest sequencer s length Cor the closest value to 1t 5 If your sequencer s have a reset output plug it into SeqSQUARED s RE SET IN jack 6 Reset your sequencers and seqSQUARED They should now be in sync 7 Plug the outputs of seqSQUARED into something that makes sound Your first patch 1s complete Now go to the next section and program it Programming Your First Pattern 1 Enter EDIT MODE by pressing and holding the EDIT ENTER button unt1 the EDIT MODE indicator lights up solid showing you are in EDIT MODE 2 Move the PAGE control fully to the left Neither of the PAGE indica tors should be lit indicating based on the legend that you are on the first page of editing 3 Move the STEP control noting that the cursor moves around on the step display Note also that INPUT A s indicator is solidly lit for all 8 steps This 1s the default when seqSQUARED 1s powered up Select a step that you wish to program to something other than INPUT A
5. the sequencers from that base pattern and put some fill notes and variation in it Now program seqSQUARED to have a pattern containing the base sequence with the variated sequence occuring only every 4 steps or so ie A A A B but turn up the CHAOS control a bit Now every once in awhile instead of playing that basic sequence you ve programmed in during the A parts it will throw ina different note from the other sequencer or miss a note if you ve turned some steps off A Touch of Nothing This 1S a variation on the above setup but in this case you set up your inputs as follows Input A Nothing plugged in Input B Cand above Your inputs Now you program a sequence something like B B B C B B B C or whatever inputs you have setup The idea is to not include input A in your pattern Now you have a bank of OFF notes in A Turn up the chaos control just a bit and every once and awhile SeqSQUARED will now drop gates CVs instead of playing them LFO Crosstalk Have some sequencers plugged into one or more of your inputs but then plug an LFO into another input Now you can switch between LFO modulation and a sequential pattern This could be really interesting for pitches These are just some ideas Experiment

SEQSQUARRCL The Analogue Pattern Generator USER MANUAL REV 1 Brought to you by HEXINVERTER NET Introduction ABOUT THIS MANUAL Anywhere you see text coloured LIKE THIS indicates a hyperlink Click 1t to go to the corresponding page website Greetings Thank you for your interest in purchase of SeqSQUARED It is my hope that you find whatever creative tool it 1S you are looking for in this design of mine Check out the QUICK START GUIDE for getting up and running fast This project was made possible through the excellent online synth DIY com munity and their trustworthy attitudes As project funding was acquired through pre orders it would not have been possible without the support of everyone that committed to pre ordering Thank you for making this happen This 1s the user manual for this project and will walk you through how to use seqSQUARED It will also detail its technical ability You can find the ASSEMBLY MANUAL AT THE HEXINVERTER NET PROJECT SITE 1f you are bu11d1 ng your own module If I have not explained everything you wanted to know about the module here and you have read the entire manual my apologies for wasting your time Please email me at hex at hexinverter net or visit the Muffwiggler forum and we will resolve your issue Frequently Asked Questions Here I will answer some of the most commonly asked questions Please read through all of these before contacting me with questions will 1t
8. e a percentage change of adding some musical variation when a note sounds Can I use the cCV Gate inputs for switching other things Yes you most certainly can while labelled cv and Gate the two 1n puts are actually just independent analogue switches You could switch two separate channels of gate signals and no CV for instance You could technically switch between different signals of any type LFOs random voltage generators etc You could also use audio although that isn t particularly recommended as the multiplexer chip used isn t really designed to handle audio It might not sound that great but feel free to experiment One thing to note is that the input cannot process negative voltages Because it 1S designed to multiplex sequencers which typically only produce positive going control voltages it will simply clip any neg ative voltages and they will not come out the other end Is 1t easy to build Assembling your own seqSQUARED is not terribly hard but it is definitely not a beginner s project Read through the ASSEMBLY MANUAL and see if it seems doable yourself when I plug in two or more sequencers and turn up the CHAOS control 1t doesn t randomize them like 1t should It Just stays on Input A what s wrong Have you programmed in a pattern yet seqSQUARED does not know what number of sequencers to randomize between until you have used them in creating a pattern so when it first starts up
9. f the one you have programmed It could be the one you have pro grammed depending on the random selection When the CHAOS event happens the CHAOS indicator lights up when you program your pattern into seqSQUARED 1t automatically determines based on what inputs are present in the pattern ie A B and C but not D what sequencer inputs you are using This means that it will only ran domize between 3 of them if you have only used three in your pattern This prevents it from occasionally selecting sequencers without any in puts Still not clear Here s an example Let us say you only have two sequenc ers plugged in but you want to introduce some chaos function into them When the random sequencer 1s picked if SseqSQUARED had no way of knowing how many sequencers you have plugged in it would select from sequencer A B C or D regardless of whether there is anything plugged in or not This would cause some blank notes gates when an input that isn t A or B 1s selected However SeqSQUARED scans the pattern you have programmed and looks at what the last input you have programmed into your sequence 1s This 1s the logical breakdown As you can see if you were to say populate Input Source A and C but NOT Input Source B SeqSQUARED would think you have something plugged into B and would select 1t sometimes when generating a random input source In this way you can trick 1t into injecting blank notes sometimes which c
10. in Idea The intended use of seqSQUARED is to generate complex sequences from basic sequential voltage sources At a basic level you can use it to simply ex pand multiple shorter length sequencers into sequencers of longer length You could for example take four 16 step sequencers Clet s call them A B C and D and make them into a 64 step sequencer by programming ina 4 length pattern of A B C D This 1s the most basic use of SeqSQUARED What really makes seqSQUARED unique 1s the ability to go beyond that and generate more musically interesting structures of sequence combinations with those four sequencers you can now program something interesting like A B C D A A B B etc with up to 32 steps in length you can program quite a few bars of pat terns depending on your sequencer length and song timing If you have ever used pattern bank based editing software you may be fa miliar with this concept ReBirth Reason Fruity Loops and many other popular programs have used this concept for ages This served as my main inspiration for creating this module Your First Patch The front panel of seqSQUARED is designed to hopefully be intuitive while patching your system with it I recommend starting with a simple patch to begin to understand the mod ule You will need SeqSQUARED Two to four sequencers of any length A clock source for from those sequencers Some sort of voltage controlled voice Let s
11. it only sees Input A If you want to use seqSQUARED to simply randomize between 2 or more inputs non stop you can do that No problem make a pattern only one step in length and set that single step to the last input you have filled with a sequencer For example if I had 3 sequencers plugged in only I would set that one step to Input Source C If I had 4 sequencers I would set it to Input Source D Get 1t Features Technical Attributes Runs at 12 OR 4 15V DC without modifications 50mA 12V 30mA 12V 15V 1S expected to be a little more Internal 5V regulator means no 5V supply needed Eurorack compatible design Analogue user interface potentiometers and LEDs instead of encoders and LCDs Switch inputs respond to O to 5V CV and Gate inputs respond to 0 to 5V Clock input responds to O to 5V Switch Features Two programmable 4 to 1 channel analogue switches CV and Gate User defined switching pattern via a simple user interface User definable pattern up to 32 steps in length Internal clock divider with sequencer length user programmable Easily select between common sequencer lengths with Divide control C1 4 8 16 32 Other Features Chaos feature introduces a percentage chance on each clock pulse that the switch will grab a random sequencer s CV and Gate instead of the one that 1S programmed Both Divider and Chaos controls are voltage control lable Quick Start The Ma
12. ly The user selects through the pattern editing the steps they wish to edit until the desired pattern 1S programmed The pattern changes take effect the moment the step 1s written by pressing the EDIT ENTER button For a step by step example read the QUICK START section of this manual Programming patterns longer than 8 steps seqSQUARED can handle a pattern of up to 32 steps in length These 32 steps are divided into 4 pages of 8 steps each when seqSQUARED 1s first turned on the pattern length is set to 8 steps To change the pattern length the step length is selected by navigating to the PAGE and STEP on that page that 1s the desired final step in the pattern the STEP MULT button 1s pressed quickly and a write animation 1s played The new pattern length is written to memory and effective immediately AS it plays back your pattern you will notice that the page now turns as you step past the 8th step into the other pages of the pat tern 1f the pattern length is longer than 8 steps Some Patch Ideas Now that we have examined how to use seqSQUARED I thought it would be fun to give you same patch ideas that may hopefully help to inspire you to be creative A Touch of Random Probably the most practical use of the CHAOS control is to load some in puts with sequences of similar composition and introduce some random probability into the mix For example program a duplicate bassline on two sequencers but then change one of
13. ould be very interesting Here 1S how seqSQUARED thinks on this matter when scanning the pattern for your reference and creative abuse Is Input D Present in the pattern If yes 4 sequencers to choose from If not Is input C present in the pattern If yes 3 sequencers to choose from If not Is input B present in the pattern If yes 2 sequencers to choose from If not There 1s only one sequencer to choose from CV OUT GATE OUT It probably comes as no surprise to you that these outputs pass their respective active input s signal out while labelled cv and Gate they are actually interchangeable Feel free to use both for Gate or both for CV as you please Programming Modes SEQUENCE MODE This is the mode seqSQUARED 1s in on a fresh power up In SEQUENCE MODE SeqSQUARED shows the indicator advancing from left to right through the steps and their corresponding Inputs as they are selected This mode 1s ALWAYS running in the background no matter what you are editing at the time In this way the module continues to run even when you are editing a pattern EDIT MODE EDIT MODE 1s where you program your pattern of sequences into sSeqSQUARED EDIT MODE 1s also where you set the length of your pattern EDIT MODE 1s accessed by pressing and holding the EDIT ENTER button until the EDIT MODE indicator is lit To leave EDIT MODE you press and hold the EDIT ENTER button until the indicator is no longer lit
14. sync with my other modules Do your sequencers synchronize to your other modules Then yes se QSQUARED will sync to your sequencer s so if your sequencers are synced SeEQqSQUARED will work with them as well seqSQUARED takes a positive clock pulse 0 gt 5v as clock input and is intended to be clocked from the same signal driving your sequencers Each time your sequencer steps seqSQUARED s clock indicator LED flashes show ing you that 1t 1S counting the steps until 1t switches to the next se quencer What makes 1t different from any other sequential switch on the market Imagine four 8 step sequencers plugged in Let us call them Sequencer A B C and D Most other sequential switches can only switch incrementally ie A B C D A B C D and so on They usually only have as many steps as they have inputs 1e 4 and just rotate between the inputs They also only process one type of input at a time thus you need TwO switches to switch CV and Gate The really fancy ones let you select which input is active via CV e 1 00V A 2 00V B etc SeGSQUARED can be any pattern you want You can very quickly program it to go for example A A A B A B C D A C B D and so on Up to 32 STEPS LONG If you have ever used Fruity Loops or another pattern based editor you can probably see the potential usefulness of this module already It also sports a feature called Chaos which allows you to introduc
