Description

Edit description

The Tiptop Audio BD909 module brings the legendary punch of the TR-909 kick drum into your Eurorack setup, offering both the classic sound and a modern twist with enhanced controls. At its core is a sine-wave-shaped triangle VCO responsible for the iconic thump that has fueled countless dance tracks. This module doesn't just replicate the past; it extends it. With independent controls for accent levels and a high-powered overload circuit, you can sculpt your sound with precision, adding grit and texture as desired.

Three intuitive tuning knobs—Osc Tune, Tune Attack, and Tune Decay—allow you to shape the frequency of the oscillator, creating everything from subtle shifts to dramatic sweeps. The overload feature injects warmth and distortion, delivering everything from gentle saturation to full-on chaos, all controllable via CV input. Plus, the BD909's accent capabilities offer dynamic control, providing an additional layer of expression that can be manipulated with ease.

Compact yet powerful, the BD909 is an 8HP module that fits seamlessly into any Eurorack setup. Whether you're recreating classic beats or exploring new sonic territories, the BD909 provides the flexibility and character to elevate your sound.

Authentic TR-909 bass drum circuit adapted for Eurorack
