COnTROLS & OPERATiOn
Thepanelhasbeenlaidoutin
mostobviousmonosynthstyle
manner.Wetookadvantage
ofalltheinternalpatchpoints
providedbyDoepfer.Also,
therearenormalledconnec-
tionsmadebehindthepanel
soyoucanusetheKMSasa
selfcontainedanalogsynth
voicewithoutevenplugging
anypatchcablesin.Thesexed
connectionsaremarkedby
withrespectivefunctiontyped
withintheBLACk BOXES.Ofcourse,
therealfunstartswhenyou
breakthembysimplypatching
anythingintotheirrespective
inputjacks.

ules:VCO 7,LFO 8,VCF 9,
VCA 10 ,ADSR 11 ,slewlimiter
12 andinverter 13 .Allofthese
canbeusedindependently.For
furtherinformation,pleasere-
fertoDIYSynth’sownmanual.
MODIFICATIONS
We’vemadesomeminormods
totheapplicationsuggestedby
Doepfer.FixedVCFoutputsare
nowmixedindifferentcongu-
rationandtheVCAoffsetcan
beadjustedbythetrimpot 6
ontheback.
Bydesign,theVCFresonanceis
providedbyfeedingtheoutput
backin.Wefounditfunto
actuallyopenupthefeedback
loopforroutingthesignalout-
side(anyoutput)andback
(
