Mutant BD9 Bass Drum - 13HP

Hexinverter Mutant BD9 Bass Drum

Rather than being a continuation of the original Mutant Bassdrum, the Hexinverter BD9 explores entirely new sonic landscapes. The module includes a sub-oscillator for extra thickness, while its primary VCO is capable of producing both classic 909-style bassdrum sounds as well as square waves. The module’s pitch modulation can be adjusted via dedicated pitch delay. control, while a click generator dictates the intensity of the attack, adding punchiness or subtleness to the overall sound. The module’s timbre can be altered via the drive control, allowing it to change from warm analog type sounds to harsh and overdriven hits, which get even fatter when paired with the sub-oscillator.
