Route one of the drum voices (usually the Snare noise generator or the Cymbal mix) back into the Filter Cutoff Control Voltage input.
If you are ready to take the plunge into hardware modification, ensure your workbench is stocked with the proper equipment: drumbrute mods
The Arturia DrumBrute is a popular analog drum machine praised for its hands-on workflow, sequencing power, and affordable price. However, many production purists find its raw analog voices—especially the snare and kick—a bit polite or lacking in character.
Increasing feedback or clipping in the kick circuits for more 909-style punch. Kick 1 & 2
The DrumBrute features individual audio outputs for almost every voice. When you plug a cable into an individual output, that voice is removed from the main mix. Modders utilize this by building external patch bays or internal feedback routing. By routing an individual output back into an aux input or an internal op-amp stage, you can create a self-generating distortion circuit that responds dynamically to the sequencer's velocity. Technical Overview: The Anatomy of a Mod Wire a SPST toggle to short the two
Tuning this circuit involves changing the capacitor value in the Twin-T notch filter (the circuit responsible for the kick's resonance). Increasing the capacitance value lowers the fundamental frequency range.
Opt for Alpha potentiometers and Nichicon capacitors. Cheap components wear out quickly and add unwanted electrical noise.
The Color parameter acts as a built-in "mod" button. Locking the Color function allows you to use two different, dirtier, or more intense versions of each sound within one sequence. 5. Conclusion This public link is valid for 7 days
For those who prefer not to use a soldering iron, the sound of the DrumBrute can be significantly altered through external means:
The DrumBrute is fully analog, which means its sound is generated by circuitry, not samples. This allows for physical manipulation of the components (resistors, capacitors) to change the behavior of the circuits.
