TipTop Audio Hats 909
Introducing the hats909, part of TipTops new series of drum modules that brings those classic percussion into the modular synth world, instantly turning your system into a self-contained music machine.
The hats909 is the tr-909's original closed and open hi-hats circuits adapted for use in eurorack modular synthesizer format and was tested to sound like a fresh machine coming out of the assembly line back in the 80's. on top of the original, we have added some great new features that expand the sound palette of hats that can be produce with this small yet powerful module.
The hats909 original circuit is made by a combination of low-fi 6 bit sound samples that pass through a series of analog elements to provide envelope and filtering to the source sound. the hats909 module allows for manual and voltage control of the sample's tuning which provides anywhere from crushed hats to short ticks and the original sound in between. a modulation switch allows you to tap a voltage control to either the tune input or the internal vca for modulation with external control signals or for adding am or fm synthesis in the audio range from external oscillators, other drum sounds, or just about any sound source. hats909 also offers a switch for a direct tap to the output of the original sample, bypassing all other internal analog processing, giving you the source to be used for synthesis any way you'd like with your own modules.
Just like the other drums in this series, the hats909 high-powered output gain stage allows you to further harmonize the sound through distortion and clipping. on each gate input, we have designed a dual pulse-shaper circuit so you can trigger your hats909 with trigger/gate signals from step sequencers, clock dividers, or any other pulse/clock sources.
