Analog High Hats

BLM HATS
WIDTH: 8HP
CURRENT: +21mA, -13mA

What does this module do?
This is a self contained analog high hat module. This is a Transistor based VCA design. It is influenced by the DR110 drum machine. The original circuit used 4 oscillators to make the metallic audio sound. I added the original 4 oscillator, and an extra 6 oscillator circuit. The 6 oscillator version is doing a double XOR ringmod (internally). You select that by switch.

The 4 oscillator design sounds more crunchy, where as the 6 XOR circuit sounds more polished with sheen. You can blend in the amount of white noise in the mix labeled 'sizzle'.

Internally, the audio is passing through a few high pass filters, making the output sound very high in frequencies.

The module by itself is not exciting. But in the mix, with other percussion modules, this is your favorite-go-to module. It sits almost perfect in the mix.

There are two triggers. One is for 'Open' sound. The other is for 'close' sound. Both open and close have there own decay knob to adjust the length of the audio tail.

There is a tone control, labeled LPF. Use this to taper off some of the high frequencies.

Instead of adding an 'accent' control. I made both triggers voltage variable. 5V triggering is the normal expected input. So a 3V trigger will sound softer in volume. 10V trigger signals will sound louder.

This module is as simple as it gets, just patch your arturia beat step pro and use the drum track.

Features

-both trigger inputs are voltage variable. You can get softer audio, with softer trigger voltage.
-2 voice metallic noise generator
-2 decays (open and close)
-2 Flavors select by switch.
-Normal mode, and Sustain mode, selected by switch.
-frequency adjustment of the internal XOR ringmod.
-classic roland sounding transistor based VCA.

Why get this module over the Shimm module, or other high hats modules?
-Ease of use, ready to go. No sound exploring needed.
-Want the classic transistor based, crunchy sound.
-lower budget
-Sits very well in the drum mix.
