3. four hands when doing jobs like this making just a handful of controls take a decent amount of time and endurance to complete let alone 8 or more sets of controls The general concensus is that in analogue synthesis you can never have too many modula tion sources Despite its only providing 8 steps of control voltage sympleSEQ can still satisfy many builders with 16 or 32 step sequencers already dedicated to pitch modulation by provid ing extra modulation sources for filters or anything else you can control via control voltage Most of all however sympleSEQ s target audience is people new to do it yourself DIY syn thesis When most people think analogue synthesizer something like Pink Floyd s famous tune On the Run probably comes to mind So it is only natural that nearly every beginner lusts for the sound of an analogue sequencer The task of building one for a beginner up until now has been one of great difficulty for most due to the lack of documentation and the ex treme complexity of wiring such a thing to the panel for use afterwards Enter sympleSEQ using a unique dual board design primarily board mount potentiometers LEDs and switches you can build yourself a simple analogue step sequencer with little elec tronics Knowledge Note that sympleSEQ does not do every single thing that a more complex large and expen sive sequencer does There may be some features you miss voltage quantizing forward back and other
4. holes as accurate as possible as all 8 steps of the board need to fit through the holes nicely Once your holes are drilled it s just a matter of screwing the 8 step switches nuts on to hold the panel to the board and installing all of your panel components to the panel Now go make some music Appendix Here you will find resources that will aid you during your build Schematics You can find the the schematics at hexinverter net Bill of Materials You can find the the BOM at Google Docs Drill Template Print out this page as a drill template for drilling your control board s panel holes Tape the cut out sheet to the panel and drill away Easy there are multiples here to save the number of sheets you need to print if making multiples LED holes 5mm drill 13 64 Pots 6 35mm drill 1 4 Switches 5mm drill 13 64 Mounts 3mm drill 1 8 ONLY NEEDED IF NOT USING THREADED SWITCHES Note that you may need to file out some of the holes to account for irregularities in your sol dering job on the board An offset switch may prevent the rest of the components from passing through their holes perfectly Again this can be greatly simplified by purchasing a ready made panel from Ben at Re Synthesis NOTE YOU DO NOT NEED TO DRILL THE 6 MOUNTING HOLES IF USING THREADED NUT SWITCHES like those included in the kits from me Mounts Switches Control Panel Measurements These measurements will be of

6. things are not included but think all of the essentials are here sympleSEQ was made possible only by the extensive online community of creative minds at the electro music and Muffwiggler forums Were it not for people contributing their excel lent suggestions on feature enhancements for the prototype design and me trying to satisfy peoples requests sympleSEQ would be nowhere near the product it is now Also the cost of running such a product was made possible through pre funding accumulated by trustworthy individuals who supported the project financially from the beginning Of particular mention are those who contributed start up funding to the project Seeing only videos and forum correspondence from me about the project and placing a great amount of trust into me is something sympleSEQ would not have survived if not for so would like to put out a thank you to everyone who placed their financial trust in this project There is no way could have funded the start up cost for this project myself so it just goes to show what many people s small effort can do when summed up together Without the amazing do it yourself community we have and the power of the internet none of this would have been possible It is a truly awesome spectacle to see so many unique projects realized with the power of com mmunication technology Thank you all for being a part of it If you have not heard Ben of Re Synthesis is going to be selling panels to com

SYMPLESCU ve U Another simple to build analogue step sequencer brought to you by HEXINVERTER NET electronics projects for musical synthesis Assembly and Operation Manual rev 2 Introduction Hello and thank you for your interest in or purchase of sympleSEQ This is the build manual for the project You will find the schematics as well as an assembly guide printable drill template and tips on how to get the most out of sympleSEQ This project was born out of a serious lack of simple analogue hardware sequencers available to build There are oodles of sequencer designs out there ranging from simple to complex but the actual construction of said devices is usually quite laborious regardless of the electri cal complexity functionality By design a sequencer is a fairly simple device so this tempts many people to not use printed circuit boards when assembling one and just build it all on perf board The actual logic circuitry for a sequencer is usually quite easy to understand es pecially in the case of a design built around the CD4017 decade counter known by many as the Baby10 like this one Where builders encounter hardships however is in the extreme redundancy of wiring the controls for these devices Each step in the sequence requires a potentiometer knob toggle switch and LED at minimum If you have ever soldered wires to panel components you probably Know how delicate of a process it is it would be nice to have
9. d flip the board over so that it s resting on the socket and then tack only one leg in place Now touch the soldering iron to the one leg while flattening the board onto the socket with your hand seating it flush against the board being careful not to burn yourself of course that way you can get the socket tacked in place perfectly before soldering up all of the pins Solder in the 3 voltage regulators being careful not to overheat them Step 5 Install Electrolytic Capacitors Install the remaining two electrolytic capacitors being careful to note the correct polarity The shaded half on the silk screen legend indicates the negative lead of the capacitor Step 6 Install Headers F a The last part soldering step is to install the male header into the OPPOSITE side of the board You must also install the power connector or wires as indicated By doing this you are mak ing it so that the logic board will plug in to the back of the control board So just to make that clear when you are looking at the component side of the board we have been working on the header should be facing AWAY from you on the other side of the board when installed cor rectly Done You are now finished the Logic Board assembly We will do the panel control wiring in its own step later Continue on to the Control Board assembly below Control Board Assembly The control board is regretfully pretty redundant to put together bu
10. dy You may choose not to use knobs at all based on this if you wish to save cost panel space Assembly Guide When putting your sympleSEQ s together recommend following a set of steps have synthe sized in order to do things in a logical manner Your mileage may vary so feel free to experi ment and come up with a better system If you re a seasoned electronics person you will prob ably find most of it does not apply to you so feel free to just skim through it Soldering Tips If you have never soldered before highly recommend doing some research first before em barking on this project list a few videos below that should be all you need to get up and run ning making excellent soldering joints A decent temperature controlled iron is expected for you to be able to complete this project It is possible that you may damage some of the com ponents while soldering them in if you are using a poor quality iron and have to hold the heat to the joint for too long Something can add that I think is very beneficial do NOT use sponges as tip cleaners NEV ER use a sponge Get yourself one of those wire steel wool looking tip cleaners found a pair for 10 on eBay There is simply no comparison A sponge seriously damages your iron Why Well first of all when you plunge your nice hot tip into a sponge covered in cool water it rap idly cools your tip Metal does NOT like rapid heat changes and it also causes your tip to cool of
11. f somewhat which makes it work to get back up to operating temperature if you have a good iron you probably won t notice it but with a crappy iron it will probably mean you have to wait after cleaning your tip to get back to soldering The number one advantage of using a wire tip cleaner is the fact that you will pretty much never have to replace your tip due to it not damag ing it Seriously have been using the same tip for well over a year and am not lying when say it is as good as new cannot tell it apart from a brand new tip When used to use sponges I d have to replace my tip every few weeks due to it getting caked up from the sponge burning onto it oxidation damage Do yourself a favour and throw out that sponge They are really infe rior If you have to use one for now don t worry about it but consider upgrading in the future Anyway here are videos highly recommend watching if you have never soldered before If you watch these videos and follow what they are saying promise you will become a master of soldering in no time http www eevblog com 2011 06 19 eevblog 180 soldering tutorial part 1 tools http www eevblog com 2011 07 02 eevblog 183 soldering tutorial part 2 Once you ve watched those this video has some specific information about how to install cer tain components tips tricks so highly recommend watching it as well have watched all of these and therefore am not just blindly recommending them They
