Turn your modular system into a self-contained music machine with the Tiptop Audio RS909, a Eurorack module featuring the original TR-909 analog rimshot sound generator circuit.

Adapting the circuit to the modular format has allowed for added special features like independent accent level, a high-powered gain stage, an input pulse-shaper, and two frequency controls for the two internal oscillators, all without compromising the signature sound of the TR-909 rimshot drum. The module ships with a ribbon power cable.

The Making of the RS909
  • Tiptop Audio uses an exact reproduction of the original analog circuit for the RS909. Its sound is generated by a clever set of three T-bridge oscillators, each producing a damped sine wave at a different frequency. The mix of those oscillators goes through a VCA whose gain is controlled by an envelope generator providing the well-known attack that gives the sound its unique feel.
  • The RS909 brings the frequency control of the two internal oscillators, OSC1 and OSC2, to the front panel, allowing for adjustment of their pitch, and thereby extending the sound of which this circuit is capable, allowing fine adjustment of the classic sound.

 

Advanced Circuits
  • Like other drums in this series, the RS909 includes a high-powered output gain stage capable of producing hot signals. 
  • 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.
