Rated 3 out of 5

Excellent but Partially Flawed Bass Synth

So the Behringer TD-3 is definitely fun when you get the hang of it but it also misses the mark on a couple of features. First off I have never used a real TB-303 so I'm not comparing it to that. I'm just commenting on this as a unique piece of gear. First off this thing sounds great AND fat. I found that the square wave oscillator is almost always better sounding the then saw. The controls are very intuitive and really are just asking to be tweaked in a live take. I found that for my purposes it was more useful to set the accent, decay, envelope, & resonance at my desired levels and just tweak the filter cutoff. Speaking of the knobs, I have to take off a point for the decay knob. I can barely hear an envelope decay of the filter with this thing. It is VERY fast and I really couldn't hear much difference between the completely closed and open values. This misses the mark even if it's exactly modeled after the 303. Also I know Behringer were going after making a faithful recreation of the TB-303 but the method for inputting notes is very cumbersome. Apparently it is exactly as it is on the 303 but it is not intuitive at first use. You have to enter all your notes first and then enter their lengths & any rests. It's not so bad after you get the hang of it but it leaves something to be desired compared to the modern Roland TB-3 which is a pretty great and intuitive sequencer. I take another point off the TB-3 for its horrendous USB MIDI. In short it is unusable. It creates a digital hum that of course you could mostly remove with notch filtering or something like iZotope RX but it should simply not be there. Standard din MIDI however does not have this problem and neither does analog sync. For the money the TD-3 delivers strong & powerful bass with pedigree. The various hardware color options make it fun finding the perfect counterpart to your studio or live setup. Honestly I hope to never part with mine and I truly have zero gear lust for a real 303. There may be flaws in comparison that I just have no concept of but I've recorded and jammed with the TD-3 and it simply is fun to use.

About Behringer TD-3

TD-3-BK
Only produced from 1981 to 1984, the Roland TB-303 was a tremendous commercial flop as a replacement for the bass guitar, however it soon found its place as one of the most-loved synthesizers for what became known as Electronic Dance Music (EDM). An ultra-affordable and faithful homage to the iconic synthesizer that spawned house music, plus an all-new Distortion circuit, the TD-3-BK lets you conjure up virtually any sound with incredible finesse and ease. With its pure analog signal path, 16-step Sequencer and authentic VCO, VCF and VCA filters, the TD-3-BK is sure to become one of your favorite synthesizers.

Pure Analog Signal Path
Great care has been taken in engineering the TD-3-BK, including the true to the original VCO, VCF and VCA designs and pure analog circuitry with matched transistors. This highly-focused attention to detail is what gives TD-3-BK its ultra-flexible sound shaping capability, which covers everything from super-fat bass and lead tones to stunning effects - all the way out to the otherworldly sounds of your imagination.

Rock Right out-of-the Box!
Your TD-3-BK comes ready to rock, thanks to its default signal routing that doesn't require lifting a single patch cable to instantly create amazing sounds. The highly-intuitive layout lets you easily tap into the inspired sounds of 1980s and '90s progressive rock, wave, EDM and synth-pop music tracks that made rock and roll history - or to design incredibly fat and original sounds that will make you a legend in your own right!

Versatile VCF
The very heart of TD-3-BK's sound is its versatile 24 dB/octave filter, which lets you freely experiment with the low-pass Cutoff frequency and Resonance settings to dial in the perfect sound.

Vintage Oscillator
TD-3-BK's authentic Voltage Controlled Oscillator (VCO) with transistor wave-shaping circuitry is ultra-easy to use and provides your choice of reverse-sawtooth or pulse waveforms for the ultimate in sound creation.

Onboard Sequencer
The onboard sequencer with 7 tracks allows you to program up to 16 steps of notes and rests and save them as a Pattern. You can record, save and recall up to 250 patterns, all of which can be stored in the 4 Groups. Your sequences can be played either in Keyboard mode, where you create and store the pattern, or Step mode which allows you to interact while composing a pattern.

Kick it Into Distortion!
We saved one of the most exciting features for the last stage in the all-analog signal path - Distortion! When you want to add even more power to your performance, just flip the Distortion On/Off switch and dial in the perfect amount of Drive to push the "envelope" to the max. The crowd won't know what hit 'em!

16-Note Poly Chain Ready
While it is a monophonic instrument (one note at a time), TD-3-BK's 16-note Poly Chain function lets you combine multiple synthesizers for up to 16-voice polyphony - plus provides vastly improved reliability and stability over its 1970s and '80s predecessors.

Controls & Connectivity
We just can't help ourselves - like you, we're gear-heads, too. For those who want the numbers, TD-3-BK has 11 controls and 28 switches to give you direct and real-time access to all important parameters, all laid out in a highly-intuitive format that puts the joy back into your music creation. And you can expand TD-3-BK's tone-sculpting capabilities beyond your wildest dreams by utilizing the multi-I/O patchbay to connect external devices!

Unleash Your Imagination
When it comes to not just pushing envelopes but creating them, TD-3-BK gives your imagination its voice - and it's so very affordable. When modern performance calls for classic analog sound - it calls for the Behringer TD-3-BK!
