Phase Plant Review

KiloHearts phase plant

KiloHearts is a comparatively small developer from Sweden, yet, they’ve confidently attempted to tackle the quest for the ultimate VST synthesizer. Their incredible Phase Plant is the result of this. With a semi-modular workflow, Phase Plant can essentially be any synth you may ever want, in one package.

Phase Plant currently offers four signal generators, Analog, Wavetable, Sample and Noise, which you can insert multiples of in one patch. The added utility modules allow you to group generators and mix them, before sending through to effects.

When you’ve just opened Phase Plant, the plugin is a blank canvas, and unlike Serum, will not produce any sound. Within the UI you have 3 main sections, Generators, Effects and Modulators. Simple enough, right?

Generators will be your sound sources, which you can select to go through effects on the right side window. The Modulators will be your sequencers, arpeggiators, LFO’s and so on, all of these can be bound to any single knob or setting within Phase Plant.

In addition to this, Phase Plant comes with a great selection of factory presets, suited for a lot of musical styles. Creating your own Presets is also very easy and intuitive.

Serum Review

serum vst plugin whipped cream sounds lofi preset

Xfer’s Serum needs no introduction, it’s been the king of soft synths for years and years. If you’ve never heard of Serum, then this is probably the first time you’re googling VST synths.

With that being said, Serum is just as awesome as it was when it was released in 2014. Serum is a wavetable synthesizer, with two wavetable oscillators, as well as a sub oscillator and a flexible noise oscillator.

TIP: Did you know you can also create wavetables from pictures? Try it out by dragging a .PNG file into the wavetable window.

You get an awesome selection of modulation possibilites, that are easy to route to any control within Serum, you might want to. In addition to this, the FX section of Serum is awesome, with ten stellar effects to choose from.

The effects can also be modulated, combined and re-arranged, to create a bespoke signal path for your sound. While you can’t route live audio through the Serum fx section, there is a seperate plugin called Serum FX, which does just that.

As stock, Serum comes with over 150 different wavetables to use, which leads to an immense amount of possibilities. You can also easily create your own wavetables from samples, and morph between two wavetables to create entirely unique sounds.

While it’s not as outright versatile as Phase Plant, Serum is not meant to be ultimate one-beats-all package. Serum is a wavetable synth, and without a shadow of a doubt, the best wavetable synth out there right now.

Pros

✅ Easy To Use

✅ Awesome FX chain

✅ Flexible and creative wavetable oscillators

✅ Support for skins, with a massive selection online

✅ Splice rent-to-own subscription

Cons

❌ Default factory skin looks dated

❌ Can be difficult to comprehend for beginner producers

How Does It Sound?

Serum is one of the best sounding, low CPU hit synth VSTs available on the market. It’s also incredible value for money, and accessible with the rent to own plan.

You can make anything from hair standing dubstep basses, to warm analog lo-fi sounds. But, while we can tell you it sounds great, we’ll let you be the judge.

Below are a couple presets from our Lo-Fi pack coming soon!

KEYS – Purple Chupa Chup
KEYS – Fireplace
KEY – RC20 Keys
PAD – Nostalgia, BASS – Guitar Sub

Pricing

You can purchase Serum from ADSRsounds.com for $189. This is the full Serum package, with everything the plugin has to offer. A Free 3-day Trial is also available, if you want to test Serum out before purchasing it.

Additionally, Splice Rent-To-Own platform offers Serum for $9.99/month for 19 months, after which, you fully own the plugin. No hidden fees or interest, this is probably the way most people have come to own Serum. Splice also offers a 3-day Free Trial, to try Serum out before purchasing.

Phase Plant vs Serum Verdict

So the question you’ve all been waiting for, which one is better, Phase Plant or Serum? You’ll probably hate us for this, but it’s not that simple.

If Phase Plant and Serum were the same kind of synth, it’d be easy to compare and weigh the differences. At it’s core, Serum is a wavetable synthesizer, it does what it has to, better than any other wavetable synthesizer.

Phase Plant on the other hand, is a versatility giant. By inserting sound generators, you can easily beat the sheer amount of wavetable voices and modulation possibilities of Serum. That being said, this is not “bigger number better synth”, since Serum’s wavetable voices are way more customizable and editable, than Phase Plants.

Phase Plant does however shine with two of it’s main points.

First, the workflow and usability of Phase Plant is incredible and designing new sounds is super easy and fun. And second, You can literally have a patch, that is 5 different wavetables, a sub, with sampled percussion on top, and 3 arpeggiated fm loops, all being individually modulated, and passed through effects.

The keyword here would be limitation. Serum is limited to your two wavetables, a sub and noise generator. The limitations make serum what it is, and has proved time and time again, how much you can do with arugably so little.

Phase Plant however has seemingly no limit. Certainly not one that you would try to reach on a regular basis. Strangely enough, the amount of possibilities isn’t crippling, as it can be on other “ultimate” synthesizers, and this is owed solely to the awesome workflow and UI design.

Factory Content

In terms of what you get with each synth package by default, neither Serum or Phase Plant can occupy a solid first place. Both synthesizers offer a wide selection of wavetables, samples, and patch presets.

We haven’t counted, but serum feels like it has more presets than Phase Plant, however, some of them can be hit and miss, while Phase Plants presets are more often than not, awesome and inspiring.

Skins

This might not be as much of a consideration, but it needs to be mentioned. Serum is much more visually customizable than Phase Plant.

With a large community of third-party skin makers, there are tons and tons of awesome Serum skins out there, both free and paid. If you’re looking for some new free Serum Skins, check our list of the 20 BEST FREE Serum Skins out there.

While there isn’t a rich selection of third party skins for Phase Plant, we recently learned, that by editing the colors.conf file in the kiloHearts folder, you can change colors, or even insert a background image for Phase Plant as well as other snap-in modules like MultiPass.

Price

When comparing the pricing of Phase Plant vs Serum, you can start to see similarities.

Both Phase Plant and Serum have monthly subscription options, which allow you to own either plugin, for around 10$ a month. The difference between these is that With Serum you get just serum, with all the things that come with it.

With the KiloHearts subscription, you get every single thing KiloHearts has to offer. It is however a few dollars more expensive per month, than Serum.

Additionally, With rent-to own, you eventually will come to own Serum fully. The KiloHearts subscription does not have this option, and will be a perpetual monthly charge.

Subscriptions aside, the price difference between Phase Plant and Serum is just about under 20$. With serum costing 189$, in comparison to Phase Plant, which comes in at slightly above 200$.

If you want all of the KiloHearts effects and snap-ins, as well as the other plugins they offer, the Ultimate KiloHearts toolbox costs around 600$.

Verdict

If we were stranded on a desert island and could only have a computer and one synth available, we’d go for Phase Plant. It’s versatility and ease of use are inspiring and creatively satisfying. To the point, where we’re struggling to come up with negatives for this Kilohearts masterpiece.

That being said, there’s a reason that Serum ranks higher than Phase Plant on our Top 50 Best VST Plugins list. The influence and ubiquity that comes with the territory of being considered by most to be THE best synth ever created, is a testament to how good Serum is.

It’s hard to pick a definite favorite, and if you have the chance, get both. If you only have money for one, choose Phase Plant.
