I am not sure of his setup.
The EG2 could be used as an oscillator,
but I am unsure if it would track octaves.

His videos are great though!

Don't forget to download the latest OS
and the Korg "How to setup CV manual" off the Korg site.
I believe prior to the recent firmware, CV was not in tune!

Super quick first hours test of CV control from external CV/Gate keybed.
Quick and Dirty, using HOF/Strymon rather than built in space echo.
Starts and end Volca Modular, bring in reference keybed sounds during
to check tracking and pitch.

CV control of my new Korg Volca Modular.
Signal Flow:
Keyboard Controller: MS-20Kit (muted)
USB from MS-20Kit to Kenton USB2MIDI to CV OCD.
CV OCD sends out CV for pitch, gate, and trigger for the Woggle.
Sequence plays in Stochastic mode with random +4,-4 octaves on Sub oscillator on Volca Modular.
Lightly backed up by Vermona 14

p.s. Once you patch in the CV/Gate, you lose control of the built-in keybed on the Modular.
However, with the new firmware I notice it tracks the octaves well, and stays in tune.

Not that tough to adapt to the FM based oscillators with no resonance on the filter.
My virtual address has moved more to the West!

Anyone else find the Dupont connections fiddly?
Cables want to fall out, and I feel the grip should be tighter on some of the
dupont connections.

That's just the nature of such a cheap connection system. I deal with the same nightmare on the Mescaline, but I put up with it because it sounds so gooood.

i bought this cables in different lengths for the VM.They are awesome.High quality,soft silicone with a thicker pin than usual.They sit tight but not too tight.Although it can be more difficult to patch them if you use a lot of wires next to each other.Therefore i still use the old cables In crowded areas

Has anyone been brave enough to bring incoming CV into the Modular?
edit: besides the CV in. I already have the cable to allow CV/Gate according to the
PDF for 1.08 Firmware.

I am talking about other patch points such as envelopes and such.

I have experimented with taking the Woggle CV out to the MS-20Kit or Monotribe and it works fine.
(Both cases filter modulation. The MS_20Kit has direct 1/4" connections and the Monotribe is a DIY 1/8"
mod to control filter CV)

The mini keyboard CV out also doesn't mind bring ported out (works great with Random Note and Stochastic mode.
I have plenty of gear that can generate CV, such as the LFO on my Microbrute, but I do not know how well it
will like +5V on inputs meant for 3.3V.

Sure I could attenuate passively, but that would take the fun out of it!

Better cables might suit me better.
I haven't had it a week and find the connections too loose for my liking.

Going into the volca is easy with an adapter cable like this,stereo/2xmono

https://www.amazon.de/gp/product/B00...?ie=UTF8&psc=1

going out is more difficult but i use a bastle kastle as"translator"if necessary (using the same adapter cable).That's my tiny current „modular setup“ It works well together.

btw,thats a great guide for the VM

I really think I should get these cables, but I need to know if the tightness
of the Tangible Waves cables still ensures that the "normals" are broken when the TW cables are inserted and
the normals re-estabilshed when the cable pulled.

Firstly I have no idea how the Volca Modular accomplishes this. On my MS-20Kit, it is a strict mechanical jack affair.

I wonder if the normals on the Volca Modular are some sort of continuity voltage to some sort of electronic switch? No idea!

If you tell me these work fine (and I really dislike the ones that come with
the VM, I will order up a set for the VM...because I absolutely love it!

Exactly what i'm worry about as well.That the AE cables could"bend"the sockets a little.I have no long term experience though.U use them maybe 3-4 weeks now and everything seems fine.I feel no difference.And when i think i feel a difference i try a socket that never saw an AE cable and it's wobbly as **** with the normal cables as well so i think it's psychology I'm willing to take the risk,at the end the VM did not cost a fortune...

4 Korg Jam featuring the Korg Volca Modular.
Starts out Korg Volca Modular
add in Korg Monotribe
add in Korg Volca Drum (4 on the floor)
then Korg MS-20Kit.


all devices synced to midi clock for lfos




Composed and recorded live to a Zoom H1 recorder
Video FZ-1000 camera


I am trying to drag this West Coast synth so far East that its
going to get caught in the Lobster traps of Halifax Harbour!

I'd like to share a Woggle hint! (or two!)
It works great as a random trigger for semi-in-sync external drums.
-The Vermona Retroverb behaves well in this respect.
-Feed the woggle to the Env In and Cutoff Frequency.

Works great as an external S&H to synths with CV into the filter.
-Tested with DSI Mopho SE keybed
-Tested with Studiologic Sledge

How exactly is audio routed into the Volca though? Through the CV input, or by somehow adapting a 1/8 to dupont connection? Anybody here tried it like the guy with the Vox Continental?

edit: oh I’m dumb, he displays the patch in at the beginning
Still curious about other’s experience routing external audio through the Volca Modular though!

Here for the gear
My method for interfacing CV in/out to the Volca Modular...

Handiest thing I've found lately: the 1/8" jacks with wire (screw) connectors. I put small lengths of a paperclip in the screw socket, then just plug the jack into a breadboard. Hot glue 2-3 together and they're pretty stable.

Korg Volca Modular's Woggle CV sequences a Monotribe via CV/Gate for abstract noise sounds.
Later I bring the Midi controller (MS-20Kit) into the mix.
Korg Modular is low note, MS-20Kit is high note.

That's the best I've ever heard it sound.

I just wonder how hard you had to work to get to "decent"

And I'm not into the "Meditation tape" sounds at all.

Thanks.
IIRC it is just the high octave triangle on that first day.
The modular is quite easy, IMO to approach as a second sound
source for my MS-20Kit.

The CV and Gate features work well to allow this.
Now 2 weeks in, I am up to 12 patch cables.
My first semi-modular with Dupont cables.

I find the output of the 2 triangle waves too harsh, so this is what I am trying as an experiment.
Feed the audio output of the Volca Modular into a Retroverb Lancet audio input and take the EG1 out envelope on the modular
and feed the CV control on the Retroverb , with the cutoff almost open, i apply slight negative filter aomunt,
so that when the Volca Modular is in keypress sustain mode, the high frequencies are filtered out, but
in release stage, as it is negative filter amount, it lets the upper harmonics in.
This tames, for me, much of the harshness.
I keep the resonance no more than 40% on the Vermona Retroverb, otherwise I create a new type of harshness.

I wasn't using the Retroverb anyhow, so I am experimenting with different ways to tame the triangles!

In sample.
a)Korg Modular through a Vermona Retroverb
b) backed up left-hand by Blofeld then Vermona 14
c) At 0:55 I bring in the MS-20Kit usbmidi2cv controller for modular
d) Last part around 2:08 is all Korg Modular
e)S&H generated by CVOCD gate into trigger to LFO/Retroverb

Using Chris Lody's method to create pulsewaves,
this Korg Volca modular (KVM)is pitch CV controlled by an Arturia Microbrute.

a) the LPGs are all disabled (bypassed), all filtering by external In to LPF on uBrute.
b) the KVM supplies the lagged woggle to control the uBrutes filter (through attenuated cable)
the PusleWidth CV on the uBrute, the Metalize on the uBrute, and it ports out this CV to control the filters on the MS-20 Kit (MK2 filter)
c)sequenced part by uBrute, but I believe the uB and the KVM pair quite well together

Some cool tricks to try with the KVM.
Instead of feeding a trigger or Gate to EG2, feed it noise.
Play around with the attack and release and check out the effect!
(Not on this video but something I discovered today)
Any modular with noise as an audio signal should do it.

Of course with experiments, at your own risk!

More experiments with pulse-shape modulation of the Korg Volca Modular.
Guinea Pig Alert!
I fed 5V signals into the KVM and did not blow it up!
Must experiment in this era of isolation.
Since the microBrute did not blow up the KVM with its 5V signals
-The KVM is a 3.3V device, it makes me wonder what the upper
regions of safety are!
If only I had a real modular to find out!

I retired my Volca Modular after a month of experiments.
Not a big fan of the Dupont connectors, they seem loose after many connections
and it is easy to knock them out with a brush of the hand.

If I get a MIDI mod for it, I might consider brining it out of quarenteen in the closet,
along with all those Monotribes.

This was my first attempt to play with a notch up from semi-modular but
connecting the Dupont to real world is a challenge.

I did learn that you can feed higher than 3.3V into the inputs and it does NOT blow up!

Bye Bye Korg Volca Modular

EDIT: Could not relive the fascination I had with my Archer 200-in-1 electronic kit back in the mid 70s!

Here for the gear
I finally completed and troubleshot (?) a circuit that takes the VMod Pitch Out and converts it to 1 V/Oct for other synths to use. My primary interest was to be able to use the VMod's sequencer (with 'Exotic' et.al. scales, Note Randomization, and Stochastic mode) to run other synths. Hard to find those features on other sequencers (cheaply). The circuit uses two 741 op amps; one to scale up by a factor of about 5x, and the other to DC offset down a few octaves. If interested, yell.
