Critic Reviews

Behringer TD-3-MO

soundonsound.com

The Behringer TD-3-MO reimagines the classic TB-303 with a daring, modded twist, offering a wild sonic palette that diverges from its predecessor. While it excels with its expanded features, including enhanced bass response and a plethora of new controls, it veers away from the nostalgic 303 sound many seek. The intuitive nature of the original remains, but the TD-3-MO's complexity can be daunting, and the sparse documentation leaves users wanting more guidance. If you're looking for a playful, gritty experience with a unique twist, it's a solid buy, but those craving the classic 303 vibe might find it lacking.

Great not only for acid music.

After using this synth for more than two years in genres apart from acid (mainly drone/ambient), I can definitely say that it's a great sounding tool if you know what you are doing. It has better timbral options compared to the stock TD-3 by Behringer. The ability to connect it to the modular setup greatly improves the sonic palette. The plastic enclosure is not that big of a problem, especially when the synth is only used at home/studio, although it didn't stop me to use TD-3-MO in live situations, and bring it to the practice spaces. Also I really admire the decision to include the sub-oscillator, really helps to fatten the sound of this mono synth.

Everything to love about the TD-3 and more

I'm a big TD-3 fan so it's probably not a big surprise that I also love it's upgraded sibling. The enhanced midi support that includes pitch bend is a nice add on. The TD-3 distortion was replaced with overdrive that gives similar results but is far less jarring.
