Back to the 80s!

The Behringer TD-3-SR is the silver version of this much-loved bass line synthesiser, a classic reference for any synth connoisseur. Whether in prog rock, new wave, EDM or synth pop, a host of legendary acid sounds that will stand the test of time, have, and still are, being created on the TD-3-series – and its pure analog signal path! The sawtooth and square waveform oscillators form the basis of powerful and super-fat bass lines, as well as gritty leads. Added distortion, one among many effects included in the TD-3-SR, will dirty that sound even further. The TD-3-SR includes both MIDI and USB ports. Should you prefer a software rather than a hardware interface, the Synth Tool application provided is intuitive and practical – while, of course, machine-programming remains fully operable. The TD-3 series is available in an array of different colours.

Totally flexible programming, plus extras!

The TD-3 series patterns are organised into four groups, each of them divided in 2 sections, A and B. The keyboard acts as a shortcut to all the different patterns, each can then be individually selected and edited. In order to program each section, ‘write mode’ must be selected in the central control area, and then the pitch and time value of each key assigned. The ‘step’ button defines the number of steps in each pattern, which can go up to 16. Longer sequences can be created by playing patterns sequentially or chaining them in track mode which allows patterns to be played in any order. A total of 64 patterns can be stored in the TD-3-SR. A random pattern generator is also included, which can be a great help in simplifying and helping with the design of new patterns. To enable random generation the ’Start’, ‘Stop’ and ‘Clear’ keys must all be pressed simultaneously.

A portable “back to the future”

At 663 g, the Behringer TD-3-SR is easy to handle and of course fits more or less anywhere. Behringer's recreation of the original user interface allows the exact same workflow that spawned so many great bass lines and leads during the 80s. The distortion section can be added at will, in easily controlled increments. The ’ Tone Control’ function, which remains neutral in middle position, is useful for either ‘muffling’ or making bass lines more aggressive. The TD-3-SR can be clocked to any other synthesizer via the sync-in input. In addition, the CV-out (controlled voltage gate out) can be used to trigger external synthesizers.

About Behringer

The company, which was founded in Germany by Uli Behringer and now manufactures its products in China, has been known for affordable and great-value equipment since its very first product, the Studio Exciter F. An array of mixing consoles (such as the Eurodesk MX8000), signal processors, and later sound amplification and monitoring equipment, has made it possible for countless musicians to fit out their home studios, practice rooms, and mobile PAs within budget limits that were previously unthinkable. The acquisition of other companies, including Midas, Klark Teknik, and TC Electronic, meant that new product groups were added - and also resulted in the technical expertise of these companies being incorporated into product development.

Simple software programming

The provided Synth Tool allows the user to immediately access any preconfigured TD-3-SR pattern via USB. From there, patterns can easily be imported from the machine into the computer, modified at will, and then sent back to the TD-3-SR. This is done via the ‘Recall’ function. Inside the editor, note values can be changed via drag-and-drop operations, as can be the total length of the pattern. The ‘Store’ function in the Synth Tool allows patterns to be easily stored back into the TD-3-SR. Accents can also be programmed, by right-clicking on the desired notes. The value of each accent can be adjusted via the corresponding slider on the TD-3-SR. The Synth Tool software includes further control options, such as MIDI routing, PolyChaining and calibration of the TD-3 SR.

Amazing, with a couple of minor teething problems.
7zark7 04.02.2020
My unit was shipped from the first batch of TD-3's to hit the shelves, so I was expecting some minor niggles. However, so far, so amazing! :)

From an authenticity perspective the TD-3 does a great job at emulating the warm depth and high screams of the original.

If you've owned a TB303 then you'll feel right at home with this.

Yes, it's chassis is made of quite cheap plastic, but it's functional whilst the knobs and pot's (Which are the main touch points for end users) seem of high quality.

The minor gripes I have are are that it didn't ship with a UK PSU so you have to buy an adaptor, and my personal unit suffers with quite a lot of mains interference.? A ground loop isolator took care of most, but it's still quite noisy. I'd be interested to hear from others on this.

Finally the headphone jack wobbles and seems like it may not last that long from first impressions. Time will tell on that one.

With that said, the device does come with a whopping 3 year warranty as standard so any build quality concerns I have with mine can get sorted over time if required.

Having owned and sold a few originals over the years I'm more than happy with this purchase.

Its £130 for a 95% TB303 Clone!
It comes with built in distortion effect! (No need to ship it to Australia for a Devilfish Modification). ;)
Its £130 for a 95% TB303 Clone!

UK PSU not supplied. :(
Possible shielding issues on PSU creating noise? (can others please comment)
Possible weak connectors on the faceplate. (time will tell)

For the money the TD-3 is a no brainer and on the whole I'm having a blast replicating my Rebirth set up of the 90's with actual analogue hardware. A dream come true. Thanks Behringer! Top marks for keeping the vintage analogue revival going.

PS: I ordered a 2nd yellow one. Not Sorry. :)


For the price, there are no valid complaints to get you into 303 land
Tom at Obscure Machines 02.08.2020
Supposedly, this unit was built off of the work of the Open Music Labs x0x-Heart module, which is open source. That being said the TD-3 sounds the part of a 303. Of course it's not 100% like the original, but nothing will ever sound like the original and the originals all sound different anyways.However, for the price, there are zero valid complaints in regards to sound. The unit sounds the part and does it well on a budget.

Unfortunately, the sequencer also fills the part. It's archaic and cryptic just like the original, which is what led to the downfall of the Roland TB 303. Thankfully, Behringer made an easy to use computer sequencer program that is quick to get good results. Just connect the TD-3 to the computer via USB and you're off to the races. I was able to use the program without any instructions in stark contrast to the onboard sequencer of the TD-3.

Everything else like build quality is good. The machine is light, but that doesn't correlate to quality as it's probably just a single circuit board and no on board power supply. My unit did ship with a UK power plug to the US. A slight inconvenience, but I think Behringer and Thomann could eventually offer country specific plugs worldwide. The distortion circuit does not sound great, but it could be used to get extra sounds out of the machine so a welcome addition.

Overall, I would recommend the TD-3 to anyone that wants the 303 sound. For the price, there's nothing else out there that comes close and also is analog. It sounds better than the Roland TB-03 digital reissue (DOH!) for way less money. The alternate sequencer on the Roland TB-03 is better though. My answer is to get both. The TD-3 for the analog fatness and squelching filter, and the TB-03 to fill a different sonic space that digital does well. They would complement each other well.


Polite generative 303 on mains
XesNoiz 11.01.2022
I got an early version. The filter is a tad too polite even for 303 but it's not bad. I think they maybe improved it a bit since but google it if you are bothered (you shouldn't be for what you get at this price). Maybe if I a/b I'd notice but from ancient memories of using 303's this sounds like one.

What I don't like - missing that last 2% of filter oomph, no battery power (guys could have done USB here).

What I love - cheap as chips, random function. Random is is a huuge underrated feature and a stroke of genius, I swear many people would have paid double for original 303 with this. Really 303 is horrible to program, only fun to play - it's exactly why all those cool basslines made with it back in the day were kind of random anyway :D I will only ever use random sequences on this guy!


Great product
