Behringer TD-3 bassline synth takes it “to a whole new level” with a devilish modded version


It is worth noting about Behringer’s recent activity. First it announced a ‘new’ MKII version of its RD-8 drum machine – itself an emulation of Roland TR-808, of course – and now we have the TD-3-MO, a modded-out edition of the company’s TD-3 bassline synth.


This revision has an even more curious backstory; it’s a second-generation version of the TD-3 (a reboot of Roland’s TB-303 bassline synth) that appears to be based on Robin Whittle’s tricked-out Devil Fish 303. So, you might say that it’s a revised clone that’s also inspired by a previous mod project.


You may recall that Behringer provoked Whittle’s ire in 2020 when it posted a mock-up of a ‘Murdered Out’ TD-3 that appeared to bear similarities to the Devil Fish design. Though the name and colour scheme have changed, the TD-3-MO looks pretty much the same.


What this means in practice is all-new circuitry, a sub-oscillator for extra grunt, additional parameter controls, patching capabilities, a MIDI CC-controllable cutoff filter and more.




  • Analog signal path
  • Sawtooth and square waveform VCO with transistor wave-shaping circuitry
  • 4-pole low-pass resonant filter with cut-off, resonance, envelope, decay and accent controls
  • 16-step sequencer with 7 tracks, each with 250 user patterns
  • Filter frequency fully controllable via MIDI C/C
  • Sub-harmonics oscillator with switchable output level
  • Analog slide circuitry with external slide control
  • Slide Time control allows for variable slide time (up to 6 times longer)
  • Sweep Speed switch features 3 accent speed modes (slow, norm, fast)
  • Accent Sweep switch features 3 sweep combinations with high resonance mode
  • Filter FM control modulates frequency of the filter from the audio output of the VCA
  • Muffler circuitry features post VCA distortion with full bass response
  • Dedicated Accent push button to manually activate the accent
  • Soft Attack control for wide range of attack times for non-accented notes
  • Normal control for wide range of decay time for non-accented notes
  • Accent control for wide range of decay time for accented notes
  • Filter Tracking control for filter frequency tracking of the current note
  • Overdrive control adds insane spice and edge to your sounds
  • CV and Gate in/out connectivity
  • 16-voice Poly Chain allows combining multiple synthesizers for up to 16-voice polyphony
  • 15 controls and 33 switches
  • MIDI and USB implementation with MIDI channel and Voice Priority selection
