Turn your modular system into a self-contained music machine with the Tiptop Audio HATS808, a Eurorack module featuring the original 808 analog closed hi-hat and open hi-hat sound engines. The module contains both circuits and features the original choke circuit for realistic performance.

Special features for each voice include independent accent levels, a high-powered gain stage, and dual-input pulse-shaper. Filter Q and VC-Q knobs were added to the main band-pass filter for additional tuning and to allow you to generate crushed tones and self-oscillation at the knob's max position, all without compromising the signature sound of the TR-808 hi-hat. The module ships with a ribbon power cable.

The Making of the HATS808
HATS808 is a one-to-one clone of the original circuit found in Roland's TR-808 drum machine. The noise source in HATS808 is made of a mix of six analog square wave oscillators set at specific frequencies. During the design, Tiptop measured the frequency of those oscillators in several original machines and found large differences; that wasn't much of a surprise as these oscillators are made using very primitive methods with no scaling or temperature compensation. As with all the other modules in this series, the guide has been the original schematic.
Choke Function
  • The choke function is a clever interaction between the two hats that adds a feel of dynamics and movement to your groove. It is an original part of the TR-808 circuit and is fully implemented in the HATS808. The idea is simple: if both sounds (CH and OH) are triggered at the same time, the short envelope of the CH will be forced on the internal VCA of the OH. In that scenario, what you will be hearing is a short CH from both outputs
  • The nice thing about the choke is when a CH will be trigger after a long decayed OH, the CH envelope will choke (mute) the long decay of the OH and will give this great effect of interaction between the two hats
  • Using the choke function with accents can produce great rhythms
