Review: FabFilter Twin 2

FabFilter Twin 2

FabFilter has recently released Twin 2, the successor to Twin, a versatile and powerful synthesizer plug-in for Windows and Mac.

Here’s a quick look at what’s new in Twin 2:

  • Three full-featured oscillators instead of two.
  • Delay effect section with two delay lines and two filters.
  • Filters now contain all 11 filter characteristics from Volcano 2.
  • Drag-and-drop modulation system now offers 50 modulation slots (XLFOs, Envelope Generators, Envelope Followers, MIDI Sources and XY Controllers).
  • Sidechain input, which feeds the Envelope Followers and can be used to trigger the Envelope Generators.
  • Improved MIDI Learn system.
  • Brand new GUI featuring Component Buttons and what-you-use-is-what-you-see modulation interface.

First look — GUI goodness

FabFilter got a lot of people excited about Twin 2 before it was even released, by posting this introduction video @ YouTube.

The Twin 2 interface has three main sections:

  • The synth section with its oscillators, filters and delays,
  • a source selection bar,
  • and the modulation slots and sources.

At the top of the interface you will find the usual presets buttons, undo/redo, A/B and the Help button. The bottom has some general options like MIDI learn and output settings.

Every section is pretty self-explanatory. Twin 2 does an amazing job packing tons of things in a small, yet easy to understand interface.

FabFilter Twin 2 Component Button

One way FabFilter managed to do this is by using the new Component Buttons.

These buttons allow you to quickly edit 4 different parameters of an oscillator, filter or delay (i.e. filter peak, freq, response and pan). Clicking the component button shows the full interface of the component. A really nice way to keep your interface tidy.

The what-you-use-is-what-you-see interface of the modulation section looks like a winner as well. First introduced in Volcano 2, this flexible modulation system only shows what you are using.

What’s the sound made of?

A beautiful GUI is one thing, but let’s not forget this plug-in produces sound as well…

Twin 2 features 3 oscillators (hey, why isn’t this thing called Triplet?), which each have 6 waveforms:

  1. Triangle: a soft, warm tone
  2. Sawtooth: a sharp bright tone that is ideal for filtering
  3. Square: a more metallic sound, adjustable with the pulse width setting
  4. Sine: a simple sine wave, the most basic waveform without overtones
  5. White noise: has a flat frequency response, meaning all frequencies at equal power
  6. Pink noise: is like white noise but with less power in the higher frequencies)

Each oscillator can be transposed, has phase sync, detune, pulse width, sync and level/pan controls. Oscillator 1 & 2 can be ring modulated.

Twin 2 interactive filter display

The filter section has 2 filters which can operate in serial, parallel and per oscillator/delay modes. The main filter parameters can be controlled from the component button. Clicking this button opens a new display with more advanced controls. The filters have LP, HP and BP responses (12, 24 and 48 dB/octave slopes) and 11 high-quality filter characteristics are available for each filter. From smooth to extreme, from raw back to gentle, there is plenty of variety.

The interactive filter display of Twin 2 allows you to adjust multiple filter parameters simultaneously. It’s very intuitive and you can basically just let your ears do the work.

Next in the signal path we find the new delay section. Twin 2 has a full featured stereo delay, with a set of filters identical to the ones I just mentioned (so Twin 2 actually has 4 multi-mode filters).

The filters can also be set in serial, parallel or per osc/delay mode, and the amount of dry and wet signal can be set with two separate knobs.

Of course you could always use external effects to spice up your sound, but having the delay in Twin 2 has a big advantage: modulation.

Drag-and-drop modulation

Twin 2 features a comprehensive modulation system to spice up your sounds. This is where Twin 2 really shines IMHO.

FabFilter Twin 2 modulation

From the manual:

FabFilter Twin 2 offers very flexible modulation possibilities which make this plug-in capable of many sound design applications. Ever-changing parameters can make your music become more alive because an exact reoccurrence is very unlikely to happen.

The various modules of Twin 2 (i.e. osc, filter, delay) can be modulated by a number of sources:

  • XLFO — can generate almost any waveform you can imagine and can be synchronized to the
    host tempo.
  • Envelope Generator — ADSR triggered by audio or MIDI.
  • Envelope Follower — follows the loudness of the incoming audio or side-chain signal.
  • MIDI source — transforms any incoming MIDI data into a modulation signal.
  • XY Controller — lets you modulate two targets using horizontal and vertical mouse movements.

Lots of fun can be had here. You can modulate a filter with a 16 step XLFO to add some life to your sound, or use the XY controller to hook up a bunch of targets and control them all with one movement. The modulation source parameters themselves can be targets as well.

Workflow — there is time to be saved

Twin 2’s interface is easy to work with, so you probably won’t be spending too much time programming your sounds. That said, you may very well want to save some of the work you’ve done for later use.

FabFilter Twin 2 section presets

Besides saving to regular presets, the section presets enable you to save the parameters of various separate components so you can pull them up again whenever you want to.

Section presets are available for:

  • The combined oscillator section,
  • The combined filter section, including routing,
  • The combined delay section, including routing and delay filters,
  • XLFO,
  • Envelope generator,
  • Envelope follower,
  • MIDI source.

Another possible time saver is the undo/redo feature. If you are anything like me you this will sound familiar. You have this great sound but you can’t stop tweaking it, until… you actually wish you hadn’t tweaked it to the point where you’re actually looking to get back to that sweet sound you had just a minute ago.
Luckily, Twin 2 records every change to the undo history so you can easily find previous states of the plug-in.

And then next time you find a great sound, don’t forget to press Copy in the top bar, and use A/B to further develop the sound while keeping the original idea.

FabFilter Twin 2 MIDI learn

Twin 2 also features a simple MIDI Learn function. Simple in the fact that all you need to do is click the MIDI Learn button, touch the control you want to link, and adjust the control you want to use on your MIDI controller.

Do this once for all the controls you want to hook up, save the MIDI mapping and voila, you’ll be set to tweak your sounds from your controller from now on.

When in the MIDI Learn mode you will notice little text balloons conveniently display the controller number which the control is mapped to. Another one of those small little details that make all the difference.

So what do I think?

FabFilter Twin 2 has a lot to offer: quality sound, great filters, the new delays, and of course the amazing modulation system.

The guys at FabFilter focus on sound quality and usability, and it shows in this synth.
I was very pleased to see some of the best things from Volcano 2 appear in Twin 2; The what-you-use-is-what-you-see modulation system, interactive filter display, undo/redo and A/B… The addition of component buttons also allows for more components, without cluttering the screen. It is amazing to see the difference between Twin and Twin 2, what a great improvement this new interface is.

I haven’t checked all 1,600+ presets yet (!!) but browsing the “Best Of” category you get a good idea of how powerful and extremely versatile Twin 2 is. Programming the synth can be as easy or as complicated as you want, so it’s actually a great plug-in for both beginners and advanced users.

I could go on for a bit, but if you want to know more you should probably take a look at the pdf manual, or head on over to the FabFilter website for more information and make sure to download a fully functional 30-day trial version of Twin 2.

FabFilter Twin 2 is available for Windows and Mac (VST/AU/RTAS/standalone). A license can be purchased from FabFilter’s online shop for 129 EUR / $169 USD. Current FabFilter users can upgrade/crossgrade at a reduced price.

    After reading your review, I decided to try it. First thing I noticed was that the output was very low volume, but I quickly found the magic button to make it louder. 2nd, there’s great number and diversity of presets. I really hate synths that come with few or no presets, so I am pleased to see the large number with this synth. There are lots of interesting sounds too, it was fun going thru the presets and playing on my keyboard (it should have a keyboard in the software, btw), but then I loaded my current project in reaper to see how it sounded, it really sounds bad compared to other synths. I suppose bad is the wrong word, it sounds weak and frail. For example, I also use lennar sylenth synth in this project and it sounds so superior to Twin2 that it makes Twin2 sound like it was written for an Apple ][ or Atari 800. Just horrible. The other 3 VSTi synths I use in the project all out class it too.

    I suppose that I’m not giving Twin2 the time needed to explore it in depth, but I really am so disappointed with it that all I want to do is uninstall it and move on. There’s so many synths out there that I don’t want to spend time breast feeding this sick malnourished kitten back to health as it’s a runt and won’t survive anyway… not with lions like sylenth to smack it around.

    I haven’t spent a lot of time with Sylenth1, but I think it is a whole different beast. Twin 2 does its own magic, though you may not like that type of magic.

    I’m cursious, what are the other 3 instruments you used which you like better than Twin 2?

  • RICK

    The other 3 synths are imposcar, zebra and massive.

    It’s fair to compare any 2 synths because it comes down the quality of the sound it produces, no matter how they get there. Twin2 is not quality sound, it sounds like a toy, and not in a good way. Sylenth and imposcar produce a multidimensional depth and character of sound where Twin2 sounds very single dimensional. I appreciate magic, even if it’s not my thing and I have no problem giving it props, but there’s no magic in Twin2, it feels like a throwback to software made 10 years ago before software evolved to its present state. Very disappointing.

    Thanks for the info Rick. Interestingly enough I have the same feeling about Zebra. I know the majority seems to feel otherwise, but that synth always sounded very thin to me.

  • http://mmi-music.blogspot.com/ MMI

    I bought Twin2 on the strength of just one of the presets. The sound was plenty big and I felt immediately that I could build tracks around it.

    Also pleasing was that even with many instances, it didn’t completely eat my machine like some of the NI stuff (admittedly my experience is limited to the Kore Player).

    As for fullness of sound… that’s an interesting issue because there is tension between having a single preset sound rich and full and fitting those same elements into a mix.

    I have already made several pieces with multiple Twin2 sounds and not had shoe-horn them into a mix with heavy handed EQing.

    That said, as my pocketbook allows, someday the others will be mine :-)

  • CONrad

    Quality synth I say. I like fabfilter’s gear. Easy to tweak too.

    I tested it and found it too “straight”.

    I think Fabfilter make better effects than synths ;)

    It need more “analog” like oscillators.

    And not including effects may be a good thing to feel the real synth sound, but on this one, you hear it lacks something, some “fatness”.

  • solidtrax

    Thanks for this amazing in-depth review of Fabfilter Twin 2. It’s just since a few weeks we really explored the possibilities of this amazing synthesizer plugin and we are very impressed by it’s quality and wide range of interesting sounds it can produce!

    We made a 100% Twin 2 track that features 15 instances, check it out here: https://soundcloud.com/solidtrax/solidtrax-a-feast-of-speed
