3.3.2. MIDI to CV/Gate interface
SinceDarkEnergy‘ssoundgenerationworksentirelyrealanalogueandrealanaloguecontrolvoltagesand
gatesignalsareusedinternally,theunitfeaturesacompleteUSB/MIDItoCV/Gateinterface.
This integrated USB/MIDI to CV/Gate interface generates not only a pitch control voltage and a gate signal
totriggertheenvelope,italsoprovidesseveralcontrolvoltagesderivedfromincomingMIDIvelocityand
MIDIcontrollerdata.TheMIDItoCVinterfacealsofeaturesasimplebutusefularpeggiatorandasocalled
referencetone.YouhavemetthereferencetonebeforetoselecttheMIDIchannel–itistheMIDInote,that
setsDarkEnergy‘spitchCV1to0VoltsandthusbecomesthelowestnoteofDarkEnergy‘snoterange.
AllCVsandgatesignalsareprovidedviasocketsonthebackpanelofDarkEnergy.Usepatchcordsto
connectthemwiththemoduleinputsonDarkEnergy‘sfrontpanel.Soyoucancontrolthemostimportand
soundparameters dynamically via MIDI velocity and a MIDI controller.
Youmay„abuse“DarkEnergy‘sMIDItoCV/gateinterfacetocontrolanother,notMIDIedanaloguesynthe-
sizerthattstothespecicationsofDarkEnergy.
DependingontheincommingMIDIdata(noteon/off,notenumber,pitchbend,MIDIcontroller,velocity)the
interface generates:
•Thegatesignalfortheenvelopegenerator,
•CV1:controlledbyMIDInotenumbers;1V/octscaling(internallyconnectedwiththeVCOspitch
controlinput)
•CV2:controlledbyMIDIpitchbenddata(rangesapprox.-2,5Vto+2,5Vor0Vto+5V,selectedablevia
internaljumper).CV2hasnointernalconnection,itcanbepatchedtothecontrolinputsonDarkEnergy‘s
frontpanel as desired.
•CV3:controlledbyvolumeortheproductofvolumeandvelocity(selectablevialearnmode).CV3hasno
internalconnection,itcanbepatchedtothecontrolinputsonDarkEnergy‘sfrontpanelasdesired.Please
refertopage20,section(2).
•CV4:controlledbyafreeselectableMIDIcontrollerortheproductofcontrollerdataandvelocity
(controllernumberselectablevialearnmode).CV4hasnointernalconnection,itcanalsobepatchedto
thecontrolinputsonDarkEnergy‘sfrontpanelasdesired.Pleaserefertopage20,section(2).
Bychanginganinternaljumper,theCV4socketcanbecomeasecondaudiooutput.Inthiscase,CV4is
notavailableanymore.ThismodenablesyoutouseDarkEnergywithoutanycablepluggedintothe
frontpanel. The default setting is CV4.
