Sequential DSM01 Curtis Filter Module

The Dave Smith Instruments DSM01 Curtis Filter captures 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 instantly 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.
