Turn your modular system into a self-contained music machine with the Tiptop Audio SD909, a Eurorack module featuring the original TR-909 analog snare drum circuit. Adapting the circuit to the modular format has allowed for added special features like independent accent level, a high-powered gain stage, and an input pulse-shaper, plus a voltage-controlled noise source and voltage-controlled tune, all without compromising the signature sound of the TR-909 snare drum. The module ships with a ribbon power cable.

At a Glance
  • TR-909 snare drum and noise generator for use in the Eurorack modular synthesizer format
  • Sound like a fresh machine coming off of the assembly line back in the '80s
  • Original circuitry + new features that expand the palette of what can be produced with this analog circuit
The Making of the SD909
  • The sound of the SD909 consists of two main sections: the binary noise generator and two modulated triangle oscillators. The oscillators provide the low-end punch while the noise makes up the upper sonic spectrum, resulting in a combination that makes the 909 snare sound so rich. 
  • In the SD909 module, the noise generator and oscillators are variable and voltage-controllable, pushing the circuit beyond its original boundaries, offering new sounds and many variations of the original tone. The panel also has markings to guide setting the knobs to reproduce the vintage snare sound of the original machine.
Advanced Circuits
  • Like other drums in this series, the SD909 includes a high-powered output gain stage capable of producing signals up to 20 V p-p, allowing you to get an array of harmonized snare drums sounds with even tighter attacks. 
  • On the inputs, Tiptop Audio designed an input pulse-shaper circuit, so you can trigger the SD909 with trigger/gate signals from your own step sequencer, clock dividers, or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module, and ensures the same stable sound at peak power regardless of your pulse source. 
  • All these unique features make integrating this legendary sound generator into your modular synth easy, unleashing the power of real analog drums.
