Din Sync MODSEQ User manual

Dearcustomer,
ThankyouforyourpurchaseoftheMODSEQeurorackmodule.
TheMODSEQisalowcost,lowHP,8stepauxiliarysequencer.Asthenameimpliesitsprimary
dutyisformodulation,howeveritwillfunctionperfectlywellasanotesequencer.
SincetheMODSEQhasonly4knobsbut8steps,steps58sharetheknobsofsteps14butin
amirroredfashion.Theresultofthisissomewhatakintoasampleandholdcircuitbut
programmableratherthanrandom.
Readontogetthebestoutofyournewmoduleandbesuretocheckoutthepatchexamples.
Yournewmodulecomeswith12monthsfreetechnicalsupportfortheoriginalpurchaser,just
dropanemailto[email protected]ifyouhaveanyquestionsorproblems.
Againthankyouforyourpurchase,it’smuchappreciated.Anddon’tforgettokeepaneyeon
http://www.dinsync.infofortheforthcomingmodules.

Whoreadsmanualsanyway?
Iknowright?butpleasetakeaquickreadofthefollowing.
Installation
TheMODSEQhasreversepowerprotection,sopluggingthepowercableinbackwardsshould
resultinnodamagetothemoduleitself.Howeverpluggingthingsinbackwardsisneveragood
ideaandcouldpotentiallydamageotherpartsofyoursystem.Theprotectionisthereincaseof
pluggingthepowercableinbackwardsbyaccident,pleasestilltakecaretochecktheorientation
ofthecablewhenconnectingitforthefirsttime.
figure1thecorrectandwrongwaytoconnectpower
Beforeinstallingpleasepoweroffyourmodularcase.Connectoneendofthecabletothe
moduleasshowninfigure1.Connecttheotherendofthecabletoyourmodularcasebus
board,pleasecheckyourcase’smanualforthecorrectorientation.Thestripeonthecable
shouldbeconnectedto12.Wehavenowstartedusingkeyedconnectorsonourpowercables.
Ifyouhaveabusboardwithashroudedheaderpleaseconfirmthattheredstripeisat12v
beforepoweringyoursystem.Afteryouhaveconnectedthepoweryoucanmountthemodule
usingtheincludedscrews,theMODSEQrequires8HPofcabinetspace.

USAGE
TheMODSEQrequiresanexternalclocktofunction,youcanuseadedicatedclockmodule
suchastheProModularCLOQ(orequivalent)astandardgate,asquarewaveLFOoranoutput
fromaclockdivider.
CLOCKIN
Connectyourclocksignaltothisjack,ideallyyourclocksignalwouldbeasquarepulsewitha
minimumvoltageof1.5v
Waveformssuchastriangles,sinesorforexamplepressurepointspressureoutsarenot
suitableforclockingandwillcausestepstoskip.
(tip:ifyouwanttousepressurepointstomanuallytriggertheMODSEQ,usethetouchgateout)
RESET
Connectyourresetsignaltothisjack,theresetjackrequiresaminimumvoltageof1.5vto
activate.

CVOUT
Connectthisbufferedoutputtothedeviceyouwishtomodulate.
(tip:settingafiltertoselfoscillationandconnectingtheMODSEQCVOUTtothefilterscutoffcv
inputmakesforanicesampleandholdlikeeffect)

There’s8stepsbutonly4knobs!?!
Inordertoget8stepswith4knobstheMODSEQuseseachknobtosetthevoltagefortwo
steps.Thefirstfourstepsare05vclockwiseandthelastfourstepsare05vcounterclockwise.
Ifthatsoundsconfusingseethechartsonthefollowingpages.It’llmakesensethen.
Step1
The(1STEP5)knobrangeis05v
WhensteponeisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis
0v.Turningtheknobtotherightincreasesthevoltageupto5vatthefarrightposition.
Step2
The(2STEP6)knobrangeis05v
WhensteptwoisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis0v.
Turningtheknobtotherightincreasesthevoltageupto5vatthefarrightposition.
Step3
The(3STEP7)knobrangeis05v
WhenstepthreeisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis
0v.Turningtheknobtotherightincreasesthevoltageupto5vatthefarrightposition.

Step4
The(4STEP8)knobrangeis05v
WhenstepfourisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis
0v.Turningtheknobtotherightincreasesthevoltageupto5vatthefarrightposition.
Step5
The(1STEP5)knobrangeis50v
WhenstepfiveisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis5v.
TurningtheknobtotherightdecreasesthevoltageatCVOUT,downto0vatthefarright
position.
Step6
The(2STEP6)knobrangeis50v
WhenstepsixisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis5v.
TurningtheknobtotherightdecreasesthevoltageatCVOUT,downto0vatthefarright
position.

Step7
The(3STEP7)knobrangeis50v
WhenstepsevenisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis
5v.TurningtheknobtotherightdecreasesthevoltageatCVOUT,downto0vatthefarright
position.
Step8
The(4STEP8)knobrangeis50v
WhenstepeightisactiveandtheknobisturnedallthewaytotheleftthevoltageatCVOUTis
5v.TurningtheknobtotherightdecreasesthevoltageatCVOUT,downto0vatthefarright
position.

PatchExamples
ProgrammableSampleandHold
ThisisthemostbasicuseoftheMODSEQ.
ConnectaclocktoCLOCKIN
Useafiltercapableofselfoscillation,somethingsuchastheManhattanAnalogMA35isgreatfor
this.
SetthefiltertoselfoscillateandconnecttheMODSEQCVOUTtothefilterscutoffcvinput.
AdjustthefiltercutoffandMODSEQstepknobstotaste.
4StepNoteSequencer
MultyourmasterclocktotheMODSEQCLOCKINandaclockdividerclockinput.
Connectthe/4outputoftheclockdividertotheMODSEQRESET.
Youwillnowhaveabasicfourstepsequencerperfectforoscillators,optionallyyoucould
connectaquantizerbetweentheMODSEQandyourfavoriteoscillator.
CascadingMODSEQs
IfyouhavemorethanoneMODSEQandabidirectionalsequentialswitch(ortwo)andaclock
divideryoucancascadethem.
Ifyouhavetwosequentialswitches,setupyourpatchlikethis
Thefirstsequentialswitchshouldbesetas1inandXout(whereXisthenumberof
MODSEQs)thispartwillbeswitchingtheclockbetweentheMODSEQs
Multyourclocktothefirstsequentialswitchandclockdividerclockinputs.
Connectthefirstsequentialswitchoutput1tothefirstMODSEQ,connectthefirstsequential
switchoutput2tothesecondMODSEQ(repeatuptothemaximumswitchoutputsand
MODSEQsyouhaveinyoursystem)
ThesecondsequentialswitchwillbeswitchingtheMODSEQoutputsandsoshouldbesetasX
inand1out(whereXisthenumberofMODSEQs)
ConnecttheMODSEQoutputstotheswitchandthesingleoutputoftheswitchtothemodule
youwishtomodulate.

Multthe/8divisionoftheclockdividertoalltheRESETjacksoftheMODSEQsandthetriggerof
bothsequentialswitches.Ifyoumissthisstepanddependingonwhichswitchusedyoumay
findanextrastepistriggered,usingtheresetkeepseverythinglockedniceandtight.
WhenyourunthispatcheachMODSEQwillonlygetaclockwhenitsrunningforanicevisual
effect.
Youcanseeanexampleof4cascadedMODSEQstowardstheendofthisvideo.

Ifyouhaveonebidirectionalsequentialswitch,setupyourpatchlikethis
MultyourclocktoallMODSEQsandtheclockdivider
ConnecttheMODSEQoutputstotheswitchandthesingleoutputoftheswitchtothemodule
youwishtomodulate.
Multthe/8divisionoftheclockdividertothetriggerofthesequentialswitch.
InthiscaseallMODSEQswillberunningandtheswitchwillchangetheoutputs.
MODSEQasanLFO/Oscillator
YoucanclocktheMODSEQataudiorateswithafastsquarewaveandadjusttheknobstomake
differentwaveshapes.Whileataudioratethetimingisn’tveryaccurate,itcanstillbealotoffun
totry!

FAQ
Q:WhenIfirstpoweruptheMODSEQarandomamountofLEDsarelit.
A:ThisisperfectlynormalwhentheCMOSispoweredup,sendingaclockpulseorresetpulse
willinitialisetheunit.
Q:Sometimessomestepsskip.
A:Thisonlyhappenswhenusingnonstandardwaveformsforclocking,youneedtousea
squarewavetoclocktheMODSEQ.EitheradedicatedclockingmoduleorasquarewaveLFO.
