Erica Synths x Hexinverter Debut Hexinverter Mutant BD9 Module

14 Apr, 2025 Synthesizers/Keyboard Synthesizers & Modular Synthesizers

Erica Synths has announced the Hexinverter Mutant BD9, Hexinverter‘s modular take on the classic TR-909 kick.

A combination of voltage-controlled distortion and the iconic flavor of the TR-909, Hexinverter’s interpretation of this iconic Bass Drum in modular format gives it more power, grit and flexibility. The primary analog VCO offers classic 909-esque sinusoidal bass drums, but can also be switched to generate a square wave bass drum.

Mutant BD9 Features:

The primary analog VCO offers classic 909-esque sinusoidal bass drums, but can also be switched to generate a square wave bass drum
The PITCH of the VCO spans several octaves, from about 30Hz to 240Hz, and can be modulated with voltage control
A novel PITCH DECAY circuit allows you to adjust the duration and AMOUNT of the pitch-modulation envelope applied to the bassdrum, from short blips to exaggerated tom-like sweeps
The AMPLITUDE DECAY allows adjustment of the length of the bass drum, from short punchy kicks to massive booms. This parameter is voltage-controlled with a snappy CV response time, allowing you to modulate the duration of your kicks per step.
The CLICK generator is responsible for the attack intensity of the BD9. A fair amount of circuitry goes into creating this subtle punch at the beginning of the kick. The level of this effect is adjustable up to a fairly dramatic extremity.
A square wave sub-oscillator derived from the primary oscillator’s pitch can be mixed in (manually and with voltage control) to the BD9. The effect can be subtle deepness or extreme timbre changes.
The overall timbre of the BD9 varies with the DRIVE control from warm, analog bass drums at low settings to speaker-shattering overdriven sounds at high settings. Output levels are modular-level signals, unlike many classic line-level percussive devices.

Erica Synths x Hexinverter Mutant BD9 bass drum module is available now for €180 from the Erica Synths website.
