HI-HATS

Sound originates from a system of oscillators based on Schmitt triggers, generating a harmonically rich signal with a metallic character. This signal is then shaped by a resonant filter and amplifier with envelope, get the distinctive "tssss..." sound.

The module provides individual control over the closed (CH) and open (OH) hi-hat sounds. The TONE knob adjusts the brightness and character of the metallic ring, while DECAY independently sets the length for each type of hi-hat. The MAIN TUNE control shifts the overall frequency spectrum of the noise source. The feature is the CHOKE function, which emulates a hi-hat pedal by muting the open hat sound whenever a closed hat is triggered, enabling authentic, dynamic rhythmic patterns from tight accents to evolving textural backgrounds.

DECAY time can be modulated via the CV input (0V to +5V), and dynamic accents are applied through the ACC input (0V to +5V). The module is triggered via the GATE input (+5V to +12V). The processed sounds are available at two separate outputs: CH OUT for the closed hi-hat and OH OUT for the open hi-hat, allowing for individual mixing or processing.
