At some point after the release of the TB-303, creative users realised that they could get even more out of the already amazing bass machine to create unique sounds. When word got out that there were third-party mods that offered more functions and many more ways to shape sounds, synthesiser fans around the world wanted a modified TB-303. With the Behringer TD-3-MO-SR, it's now much easier to get that fantastic "modded-out" sound.

The TD-3-MO-SR has been designed with great care, including the faithful VCO, VCF and VCA designs and the pure analogue circuitry with matched transistors. This attention to detail gives the TD-3-MO-SR its ultra-flexible sound shaping capabilities, covering a wide spectrum that lets you create super-fat bass lines and pounding rhythms.

Thanks to the intuitive layout, you can easily tap into the inspired sounds of wave, EDM and synth-pop tracks from the 1980s and 90s that made history - or develop incredibly fat and original sounds that will make you a legend in your own right.

The TD-3-MO-SR features an ultra-flexible voltage-controlled oscillator (VCO) with sawtooth and square waveforms that can be tuned, shaped and even overdriven to your liking. The amazing 4-pole low-pass resonant filter has controls for cutoff, resonance, envelope, decay and accent that you can adjust and tweak to add excitement and flavour to your songs.

As it's a 'modified' version of the original TD-3, there's a whole host of amazing new functions that are sure to make your music stand out, such as a MIDI C/C controllable filter, variable slide time control, a three-mode sweep speed switch, an accent sweep switch and much more.

You can record, save and recall up to 250 patterns, all of which can be saved in the 4 groups. Your sequences can be played either in keyboard mode, where you create and save the pattern, or in step mode, where you can interact while composing a pattern.
