The Mutant Rimshot is a fully analog rimshot and clave generator inspired by the rimshot found in the legendary 909 drum machine; a triple bridged-T oscillator coupled with a state variable filter. The clave sound (not a feature of the original 909 rimshot) is achieved by using just one of the oscillators. Features

Three oscillator modes

• Rimshot HI mode brings classic rimshot sounds
• Rimshot LO gives a lower pitch range; try playing with the filter on this setting to get low tom and kickdrum sounds.
• CLV (Clave) mode uses just one of the oscillators to give you a brighter, higher percussive sound.
• A switch on the back lets you select between original and extended pitch modes. Original mode can give you rimshots exactly modelling that of classic machines (in Hi mode), whereas extended mode gives a wider range of pitch, at the expense of classic accuracy.

Three filter modes

• Use the lowpass or highpass filter modes for classic sounding rimshots
• Highpass and bandpass can give a wider range of clave and rimshot sounds, as well as completely different percussive elements (especially when turning the resonance up!)
• VCF IN lets you blend the clave or rimshot with other sounds. Try adding some filtered noise for a more acoustic sounding rimshot, or for pseudo-snare type sounds.

Novel decay and filter mod controls 

• The MOD DECAY envelope controls the decay of the VCA envelope
• The VCF MOD attenuverter allows you to modulate the filter cutoff with the MOD DECAY envelope
• Alternatively, a switch on the back lets you modulate the filter cutoff with the pitch-controlled internal VCO, for filter FM style percussive hits.

Redesigned by Erica Synths in close collaboration with Hexinverter. 

In September 2022 Stacy Gaudreau - the founder of Hexinverter Électronique, announced closing down the operations. Following their announcement, Erica Synths in cooperation with Hexinverter Électronique saw a way for their incredible and truly unique music instruments to keep on inspiring musicians and finding a home in countless studios to come. We strongly believe the effort and innovation incorporated in Hexinverter Électronique eurorack modules are far too great to prematurely become history. Erica Synths will take over the manufacturing, sales, and support of several Hexinverter Électronique modules. While retaining all functionality of Hexinverter Électronique modules, Erica Synths redesigned the hardware of modules and will provide support for reissue modules only.
