Classic Acid - Modified
The yellow TD-3-MO-AM 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, three-mode Sweep Speed switch, Accent Sweep switch, a Soft Attack control, and more. The TD-3-MO-AM 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-AM’s tone-sculpting capabilities beyond your wildest dreams by utilizing the multiple I/O patch bay to connect external devices.

Pure Analog Signal Path
Great care has been taken in engineering the TD-3-MO-AM, 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-AM 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-AM 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-AM 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-AM are fun, mesmerizing, and totally addictive.

Controls and Connectivity
The TD-3-MO-AM 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.
Expand TD-3-MO-AM’s tone-sculpting capabilities extent beyond your wildest dreams by utilizing the multiple I/O patchbay to connect external devices.
