MCV24 Overview
TheMCV24 isaflexible MIDIto analogueinterface,and anyofit’s24outputscan beconfiguredfor
anypurposesuchascontrolvoltages forVCOpitch, controlvoltagesforanymodulationdestination(suchas
VCForVCA), triggers or gates. Outputs 1 to 4 arehigherprecision12-bitDAC’s,whilsttherest are 8-bit
DAC’s,outputs1to 12areoptimisedforone voltper octavescaling, butcanalsobeset toHertz/volt scaling
(likemost Korgand Yamaha instruments). Alloutputshave a programmableslewcontrol to reducedigital
quantisationinherent in a 7-bit MIDI system, in fact this slew control onthe analogue side can produce a
smoother control voltage from an 8-bit converter than some 16-bit converters manage without the slew
control.

MCV24 Basics
The MCV24 doesn’t really have any controls for operation, once it has been programmed to do a
particularfunction, thatisexactly whatitdoes, soonceprogrammed, changing presetsis probably theonly
operationrequiredon theMCV24.However,afullunderstandingofwhattheMCV24willdoandhowtoset
itup isa vitalelementthat mustbe learnedfirst.As therequirement ofaMIDI toCV interfaceislikely tobe
differentforeveryone,itisdifficultto generate“factory” presets,as theinstruments towhich itis goingtobe
usedwithisan unknown factor.Assuming it is most likely to be a Doepfer A-100systemisfine,exceptit
wouldstillbe unknownwhat kindofcontrolisneeded.So,unlike mostpieces ofequipment,wehavetostart
learningtheMCV24byprogramming,ratherthancalling upa fewfactory presetsto experimentwith.
Ifyou absolutely musttry to maketheMCV24 work straightaway, tryconnectingthe CV1outputto
aVCO input,andCV13 outputto theGateinput, andtransmityour MIDIinputon channel1, but whenyou
need to know why - read on.

that the output CV will work within. Most of the time, this will be set across the entire keyboard, with a

SLEW
This is where the Slew function is enabled or disabled. When on, the CV output voltage is slewed,
which means it’s rate of change is slightly lagged, this improves the limitation of the 7-bit MIDI system,
althoughfornoteinformation alonger settingwouldbeusedfor portamento.(The slewtime settingisunder
theCV2 parameters later on). With controllers, aftertouch and pitch bender, a greater smoothness can be
achievedusingslew.
Thenext parameters areonlyavailable if MIDI EVENTS=notes.
VELOCITY
TheVelocity mode determines what the velocity of theincoming MIDI note will be routed to. The
optionsare:-

use-butyou never know!
RETRIGGERTIME
TheRetriggertimesets the delay between a new note being played and the trigger being generated
(Gateoutput).Witha setting of 000, there isnoretrigger, so when playing legato style (playingnewnotes
beforereleasingothers),the new note does not retrigger. At asettingof001,which is perhaps the normal
setting,the noteis re-triggeredimmediately, andasthevalueis increased(upto127),the delayisincreased,
meaningthatthe newnote isplayedimmediately,butthe actualgate outputisdelayed.Thisofcoursegives a

MIDITO (CV2)
Thisis thesecondCV routing,and issimilarto CV1functions,except thatthedestination optionsare
alittledifferent.The MIDI To function selects which MIDI event will be assigned tocontroltheselected
output(Output01 inthe caseoftheexampleshownhere).Depending onwhich eventisselected,determines
howmany edit pagesareavailable, as allunrelatedoptions are suppressedtokeep things clearer.
TheMIDIsourcesavailable for CV2 are: Off, Controllers, Poly Aftertouch, Pitch Bend and Mono
Aftertouch.NotethatCV2 cannot be controlled by notes, and adds Pitch Bender that CV1 did not have.

MIDICHANNEL(CV2)
TheMIDICHANNELpagesallowstheMIDIchanneltobeassignedtocontrolaparticularoutput
CV. Any channel between 1 and 16 can be selected here. In the example shown, output CV number 1 is
beingcontrolledbyMIDI channel 1. It is apparent from this that CV1 and CV2 can be on different MIDI
channels,though most of the timetoavoid confusion, it is perhapsbesttohave CV1 and CV2onthesame

For use with pitch bender, each value of 4 will add one semi-tone to the range, so a typical Pitch

asthe pitch wheelis centred anditis a +/-range,the rangeisconsidered to be asemi-tonein onedirection)
SLEW(CV2)
Thisiswherethe Slew function is enabled or disabled for CV2. When on, the CV output voltage is
slewed,which means it’s rateof change is slightly lagged, this improves thelimitation of the 7-bit MIDI
system.Withcontrollers, aftertouch andpitchbender,a greater smoothnesscan be achievedusing slew.
SLEWTIME
Thisis where the Slewtimeis set, which controlsbothCV1 and CV2. Asettingof 0 (OFF), prevents

LFOFUNCTION
Thisswitches the LFO onoroff for the selectedoutput.When switched on thefollowingparameters
areavailable. When switchedoff,the LFO parametermenuis suppressed.
LFOWAVE
TheLFO has 5 main basicwaveforms,Linear Triangle/Sawtooth,Rectangle(pulse),Sine, Random
(analogue)andRandom(digital). Thesebasic waveformsarecontrolledbythe Ratioparameter,whichvary
thewaveforms beyond these basic shapes.(seeRatio parameter).
The Random (Analogue) waveform produces a waveshape similar to an analogue noise generator

butalwaysatfullamplitude.

LFOFREQUENCY COURSE (LFOSync=Intern)
WhentheLFOSyncissettoInternal, thisparameter controlsthe speedof theLFO. Eachvalue relates
to 1Hz, so in the example shown above, the speed is 6Hz. The range is form 000 to 019. The following

LFOFREQUENCY FINE (LFOSync=Intern)
WhentheLFO Sync is set to Internal, this parameter controlsthefinespeedof the LFO. Each value
relates to 0.01Hz (1/10 Hz), so in the example shown above, the speed is 0.08Hz, which is added to the
previousparameterFrequency Coarse. The range is form 000 to 099.
Inthepreviousexample here was shown a Frequency Coarse of 006, and a Frequency Fine of 008,
this therefore gives an LFO speed of 6.8Hz. The range of the LFO is from 0.01Hz to 19.99Hz in 0.01Hz
steps.
LFO MIDICLOCKDIVISION (LFO Sync=Midiclock)
WhentheLFOSync isset toMidiclock,thisparametercontrols thedivision ratioof theLFOspeedin

LFORATIO
The LFO Ratio controls the shape of the basic LFO waveform. A central value of 50% keeps the
waveformsymmetrical,so theTri/SawwaveformisapureTriangle,andtheRectanglewaveisa puresquare
