The HATS808 is the TR-808’s analog closed and open hi-hat circuit adapted for use in Eurorack modular synthesizer format and tested to sound just like it did back in the 80’s. Adapting to the modular format has allowed us to add special features for each voice like independent accent level, a high-powered gain stage, a 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 shi-hats.

The HATS808 sizzling sound is made using six analog square wave oscillators mixed and processed b band-pass filters. This multi-oscillator design is what gives the 808 hi-hat sounds their unique metallic character and mask each HATS808 sound slightly different from one another. The original ‘choke’ circuitry that makes it sound so dynamic and tight is fully implemented, just like the original, but can also be disabled if needed by disconnecting the internal connection between the two hats.

Just like the other drums in this series, the HATS808 high-powered output gain stage allows you to further harmonize the sound using distortion and clipping. On each input, we have included a dual pulse-shaper circuit so you can trigger your HATS808 with Trigger/Gate signals from step sequencers, clock dividers, or any other pulse/clock sources. This eliminates the need to shape pulses sent to the module and ensure 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.
