DSM01 Curtis Filter

Resonant Low-Pass Filter

Big Sound Comes In Small Packages
Dave Smith's first-ever offering for modular synthesizer users is a big one—the DSM01 Curtis Filter, the very heart and soul of the Dave Smith sound. Featured in everything from Dave's vintage Sequential synths to his recent cutting-edge instruments such as the Prophet 12, the Curtis tone is brash, saturated, and powerful.

= Plug It and Play It

The DSM01 is a compact, 8 HP Eurorack-format module. Plug it into your modular system and that classic Curtis sonic signature is instrantly within a patch chord's reach. The filter is a resonant low-pass design that can be switched between -12 dB and -24 dB operation and driven into self-oscillation in -24 dB mode. A Boost switch lets you overdrive the input stage for more aggressive coloration.

= Integrated VCA

In addition to its Curtis filter, the DSM01 provides its own responsive, low-noise VCA with LED CV indicator. There are two separate outputs—one pre-amplifier and the other post-amplifier. This not only gives you added signal routing flexibility, but also frees your system's existing VCAs for other tasks.

Give Your Modular System the Edge
If you're a typical modular user, you're always on the lookout for new and interesting components to enhance your system. The DSM01 is an easy and affordable way to give your system a new sonic edge—with the filter that's brought some of the world's most in-demand synths their classic tone and vibe.
