Functionality
For the setting of these parameters MIDI Program Change messages coming from your MIDI device are
used.NormallyyouwillhavetopresstheprogramchangekeysonyourMIDIkeyboardorMIDIsynthesizer
whilebeeinginthelearnmode.PayattentionthatsomemanufacturerscounttheMIDIprogramchange
numbersfrom0....127ratherthan1...128asusualanddenedintheMIDIstandard.Ifthelowestprogram
changenumberyoucansendwithyourMIDIdeviceis0(zero)youhavetosubtract1fromtheprogram
changenumbersinthetableaboveasinthiscasetheprogramchangesofyourdevicerangefrom0...127
insteadof1...128.Forsomedevices(especiallysoftwaresequencers)thetypeofprogramchangenumbe-
ringcanbeselected.Inthiscaseyoushouldusethe1...128rangetoagreewiththenumbersinthetable
above.
TheprogramchangemessagesmustbesentonDarkEnergy‘sMIDIchannel(pleaserefertosection„MIDI
channelselection/learnmode“onpage19).
(2) Velocity on/off
Theseprogramchangemessagesareusedtoselectwhetherthenoteonvelocityaffectsthecontrolvolta-
gesCV3resp.CV4.Ifvelocityis„off“onlyvolume(CV3)resp.thefreechosencontroller(CV4)isusedto
generatethecontrolvoltage.Ifvelocityis„on“thevolumeorcontrollervalueismultipliedwiththenoteon
velocity,i.e.theCVvaluechangeswitheverynewnoteeventasthevelocityofthenoteeventisusedto
calculatethecontrolvoltagetogetherthevolumemessage(CV3)resp.thefreecontroller(CV4).
(3) Retrigger on/off
Withthisparameteryoumayselectwhetheranewgate/triggerpulseisgeneratedwhenplayinglegato(i.e.
playinganewnoteonthekeyboardwhilethekeyoftheformernoteisstillpressed).Thefactorydefault
settingisretriggeroff.AdditionallytheMIDIcontrollerslegato(controller#68)andsustain(controller#64)
affect the gate output in the usual manner.
(6) CV1 Key Assign Mode (Note Priority)
TheseprogramchangemessagesadjustthetypeofassignmodesforCV1.Ifhighestnoteisselectedthe
highestkeypressedontheMIDIkeyboardisusedtocalculatedCV1ifmorethanonekeyispresseddown.
Inthelastnotemodealwaysthelastnote(chronological)istakenforCV1.Referencenotemeansthatonly
thereferencenoteisaccepted.Thisfeatureisusefulifyouwanttotriggerdifferentdevicesonthesame
MIDIchannelusingtwoormoreDarkEnergy.InthiscaseyouhavetosetthereferencenotesforDark
Energy‘stodifferentvalues.
StacknotemeansthatDarkEnergyislteringoutthenoteeventthatisusedbyDarkEnergytogenerate
CV1.Thenoteeventinquestionisnottransmittedtothe(internal)MIDIThruoutputoftheinterface.Stack
modeisusedtocontrolmorethanonesynthesizersononeMIDIchannelandenablespolyphoniccontrol
ofdifferentsynthesizersonthesameMIDIchannel.
PleasenotethatusingthismodeneedstheinternalLink-interfaceofDarkEnergy.Itisonlyaccessablevia
aninternalhardwaremodication.pleaserefertopage25forfurtherinfos.
(7) Arpeggiator
Dark Energy offers an internal arpeggiator. An arpeggiator splits the notes of a played chord into a suc-
cessivepatternofsinglenotes.Inmusic,thesplitofchordsintoapatternofsuccessivenotesisingeneral
named „arpeggio“.
DarkEnergy‘sArpeggiatorusesthefollowingparameters:
•TempoofthearpeggiocanbedeterminedbyDarkEnergyitselforsyncedtoanexternalMIDIdevice.
•Directionisdenedlikethis:Thenotesareplayedbackinthesameorder,theyhavebeenplayedonthe
keyboard.
