Low-profile Portability, Full-sized Celestial Sonics

Musicians seeking the titanic aural firepower worthy of a Roman deity’s namesake, but with the mercurial possibilities of a portable form factor and cutting-edge modeling technology, will find their match with Behringer’s JT-4000 micro hybrid modeling synthesizer. But don’t let the name mislead you: the only thing “micro” about the JT-4000 is its sleek, mobility-minded profile. Each of its four voices features two analog modeling oscillators, which are armed with six waveform options that include noise, sawtooth, square, and supersaw shapes. Synthesists at Sweetwater appreciate the streamlined, ergonomic interface of the JT-4000, allowing you to painlessly navigate its straightforward tone-crafting tools, 32-slot preset bank, analog filter, and powerful arpeggiator. Moreover, its 16-note capacitive touch keyboard, 12-bit DAC, and dedicated headphone port equate to near-silent synthesis in any environment while not compromising on classic, evocative tones.

Behringer JT-4000 Micro Hybrid Modelling Synthesizer Features:

  • Portable form factor prioritizes mobility-minded musicians without sacrificing sonic potential
  • 16-note capacitive touch keyboard supports nuanced expression without additional mechanical components
  • Each of its 4 voices is powered by 2 analog modeling oscillators for robust, historic-sized tones and timbres
  • Meticulous modeling of ’80s sound engine supports six waveform options, including the iconic supersaw
  • Analog lowpass 12dB/octave filter lets you shape evocative tones brimming with vintage panache
  • Dual ADSR envelopes and a pair of LFOs provide plenty of sonic sculpting to craft distinct patches
  • 32 memory presets ensure studio-grade foundations for building sounds of your own or space to easily store and recall your work later
  • USB-C port is top-mounted for painless MIDI connectivity and deep interoperative integration
  • 3.5mm MIDI jack

Reviews

I have real regrets about buying one of these…

Because I should have bought five or six immediately.


These are so affordable, they could be a party favor.


The JT4000M is of pure pocket-sized fun.

So good I bought two
First, thank you Uli Behringer and Sweetwater for making these amazing instruments available
and at an amazing price. I just love the first patch, the fatsaw. I don't use a computer and just play live.
I midi out my Casio CT-640, into a midi hub. The output of the two JT-4000's gets plugged into a 20db clean booster
and then sent to a Behringer Dual-Phase shifter. The output of the Dual-Phase is then sent to my Aveek 5-FA mixer and
on to my Sunbuck As-336BU stereo amplifier. OMG, the sound is just smooth as silk yet also can be very powerful
I just love it and yes, two is better than one.
Music background: Played both bass and guitar with bands. Musical family background.
This thing is ridiculous. In a good way.

This thing can't be reviewed without "for the price" language. Because $. But by emphasizing the low price, you can miss out on just how great this little guy is. It sounds great. The controls are remarkably logical and easy to master. I love it and I'm trying to figure out how to talk myself out of buying another one.

Killer synth
For the price, and the size, you get a lot! So far, just using the presets and tweaking a bit here and there, but honestly, the presets sound amazing.
Music background: Drummer
Insane sound for $!
Now that this has a MIDI port, you just have to have one. I connect mine to my Komplete Kontrol with the right MIDI channels going out and it's just a complete joy. Sounds fantastic
