West Coast Semi-modular Synthesis for Volca Fans

With its true semi-modular signal path, the Korg Volca Modular brings the expansive creative potential of modular synths to the Volca platform. And with its CV inputs, it’s a sweet addition to any Eurorack synth rig. Its 16-step sequencer offers a range of scale presets to play with, plus deep randomization options for on-the-fly versatility. Practically anything can be patched into anything else on the Volca Modular, and 20 patch cables are included — that’s a lot of potential for creating your own custom synth sounds. Whether you’re expanding your Volca rig or tapping into your full modular synth setup, the Korg Volca Modular packs a ton of value into a standalone synth and sequencer module.

Extensive patchability for endless sound design options

The Korg Volca Modular’s semi-modular nature allows you to start creating sounds instantly, without any patching. With the included patch cables, you’ve got a total of 50 patch points to experiment with. You’ll be able to craft sounds never heard from the Volca range before, from evocative drones to nonlinear soundscapes and beyond.

CV in for modular connectivity

Eurorack fans at Sweetwater were pleased to find CV input on the Korg Volca Modular, opening the door for connecting it to a full modular rig. The CV-In jack receives a TRS mini stereo jack for inputting two signals. The left channels support a +/-5-volt signal, while the right channel accepts a 1-volt/oct signal (internally converted to pitch CV). Each of these signals can be further patched to specific modules on the Volca Modular.

Advanced sequencer playback modes

The Korg Volca Modular is equipped with the classic Volca sequencer, with a couple of new play modes serving up big creative potential. Bounce mode alternates between playing your sequence forward and backward, also known as round-trip sequencing. Stochastic mode gradually progresses through your sequence while randomly moving forward and backward within the sequence. And with various scales, keys, and even micro tuning at your command, plus sequence randomization capabilities, you could spend months exploring all that the Volca Modular has to offer.

Amazing versatility for under $
I love this little synth so much! Being able to toss a semi-modular synth into a bag and travel with it is incredibly fun and appealing. Korg includes patches to create FM, ring modulation, portamento, rhythmic sounds, bass synths, and there are a lot of YouTube videos for creative patching. For me, this is an instant classic. I considered getting the Moog Mavis, but the Korg has more features, is smaller, and almost half the price. If I'm being honest, I'll probably end up getting the Mavis later because you can never have enough analog!

Amazing Synthesizer
I've been able to make some really interesting sounds with this! The step sequencer is great. Thanks to the small form factor, I brought this on vacation with me recently, and it has worked amazingly. Very excited to use this on some future recordings!

A Great Introduction To West Coast-Style Semi-Modular Synthesizers (if you don't mind a learning curve)
Oh wow. This is by far my current favorite Volca. It was hard to choose between my Sample and FM before, but once this thing arrived it quickly stole the show in my mind. If you're into experimenting with sounds that aren't your typical subtractive synth melodies and basslines (though you can definitely use it
for that, don't get me wrong), and you're curious about a unique form of modular synthesis when compared to the common east coast format, this will keep you occupied for quite a long time. It compliments my modest setup quite well, and I feel a sense of completion for the first time.

It comes with a Volca-sized card (like the Volca FM) with one side showing all the patch points, each with a word and/or diagram briefly describing what they do, and the other side showing 4 basic patches to get you started and show you how to do portamento (note glide), use the modulator oscillator as a 2nd carrier oscillator, LFO modulation, and ring modulation. The poster-sized foldout user manual even has 8 more patches to play around with, titled: Western Bongo, Random Release, Gate Math, Polyrhythmic Duo, Generative, Walking Bass, Vibrato, and Dubstep Bass. You can think of the card patches as being a short minimalistic tutorial of sorts on how to do some common synth functions on the Volca Modular, while the fold-out user manual patches are more like your standard patches or "presets."

Input patch points have a clear background, outputs have a dark background. Audio ins and outs have circular, extruded "corners," CV ins and outs are straight lines and square corners. They designed this synth very well. There is even a thin aluminium plate on the main control/patch surface (yes, the silver color is actual metal). Just because of this addition, this definitely feels like a Volca+, or a "premium" Volca unit. Thanks to this, the extra sequencer functions, and of course the patch points, the slightly higher price point is very much worth it, in my opinion. Same knobs, touch controller, buttons, and overall plastic body (with a cool triangle-patterned translucent blue aesthetic on the bottom; aside from the color, very similar to the Volca FM's bottom), but that's to be expected from a Volca.

Just be careful when you actually use the patch points and cables. The cables feel fragile. It seems as though one accidental swipe of the hand across the surface with a bunch of patch cables installed could cause all the cables to break. One previous reviewer here worries me that it could damage the internal patch point connections as well. In any case, definitely treat this baby with respect. It's not built like a tank like so many larger synthesizers are. If you're going to be transporting it, please use a proper case of some kind. Something that fits it relatively snug and tight, doesn't put pressure on the knobs, and will absorb most of the shock if dropped or otherwise mishandled. There are a couple of Korg-endorsed Volca hard cases, but there are cheaper options if you don't mind DIYing a big with the foam padding.

Also, if you want to use it battery powered all the time, get yourself some rechargeable AA batteries with a decently high mAh rating and a good charger. Each Volca takes 6 AAs, which last a decent amount of time. Haven't had this one long enough for it to drain the batteries as of the time of writing this review (will update if anything changes my opinion, that is if Sweetwater lets me), but I can say my Volca Sample lasted about a week of on and off use with the provided non-rechargeable batteries. I can imagine with more hardcore, several-hours-at-a-time use, it could run out of power in a day or 2.

All in all, if you're curious about semi-modular synths in general, or just want a cheaper entry into the West Coast style format of Modular gear, this is an excellent choice (and dare I say, the only one for this price point?) to start out with!

Happy synthing!

This is a good sound box
Having a blast with this one. Just got it and out of the box you can get some great sounds. Breadboards may look a little challenging but this one isn't too bad. The diagrams/directions are fantastic. They are written in plain English without all the jargon you can sometimes get on the media platforms. It seems pretty durable even with it's plastic outer skin and tiny knobs. It can run on batteries or optional power supply.

Amazing Little Machine
After only 15 minutes of learning to use this synth, I was blown away. Yeah it may lack MIDI, may lack easy to route CV inputs (only has one CV in for Pitch, Gate, and Mod; you need an 1/8" stereo to L/R 1/8" to use Pitch and Gate from other semi-modular/modular synths), it may not have the flashiest features...but this is an amazing tiny piece of kit. It can produce everything from Ring Modulated leads to beautiful ambient atmospheres! The patch points have tons of options including the different utilities which is very useful. The sequencer modes are pretty great, especially the random steps mode. Honestly, for the price this thing is, you are being blessed with a great synth and something that can really make you experiment with routing and sounds. It may be atonal most of the time, but great for sampling for other uses (Trap, Dubstep, Wonky, House).

Paired with some guitar pedals through a send on a mixer, it can lead to amazingly beautiful atmospheres with it's built in reverb and quirky character. I would give it a 5/5, but a lone CV input and lack of MIDI IN makes it a 4.5/5.
