Classic Acid-Modified
The silver TD-3-MO-SR from Behringer is a recreation of the legendary Roland TB-303 with the highly coveted Devil Fish modification, which adds a ton of extra features and control to the classic bass synthesizer and sequencer that started a musical revolution and spawned the Acid House genre.
This modded version adds MIDI CC control to the classic voltage-controlled filter, variable slide time control, a three-mode Sweep Speed switch, an Accent Sweep Switch, a Soft Attack control, and more. The TD-3-MO-SR has 15 controls and 33 switches to give you direct and real-time access to all important parameters, all laid out in a highly intuitive format. Expand the TD-3-MO-SR’s tone-sculpting capabilities beyond your wildest dreams by utilizing the multiple I/O patchbay to connect external devices.
Pure Analog Signal Path
- Great care has been taken in engineering the TD-3-MO-SR, 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-MO-SR its ultraflexible sound-shaping capability, which covers a wide spectrum for you to create some superfunky bass lines and pounding rhythms that can keep you and the crowd grooving all night long.
- Your TD-3-MO-SR 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 wave, EDM, and synth-pop music tracks that made history.
Versatile VCF, Vintage Oscillator, and Distortion
- The TD-3-MO-SR includes an ultraflexible sawtooth and square waveform voltage-controlled oscillator (VCO) that can be tuned, shaped, and even overdriven just the way you want.
- The classic TB 4-pole low-pass resonant filter has controls for cutoff, resonance, envelope, decay, and accent that you can adjust and tweak to add tension and spice to your songs.
- When you want to go even lower, you can tap the Sub Oscillator button giving you an extra octave, more low end, and a deeper sound.
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.
- Record, save, and recall up to 250 patterns, all of which can be stored in the 4 Groups.
- 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.
- The onboard Arpeggiator features wide patterns you can build to provide a virtually-endless array of sound effects.
- Both the sequencer and arpeggiator in the TD-3-MO-SR are fun, mesmerizing and totally addictive.
Controls and Connectivity
- The TD-3-MO-SR has 15 controls and 33 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.
