Erica Synths - Hexinverter Mutant Rimshot

video upload by Erica Synths

"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. Redesigned by Erica Synths in close collaboration with Hexinverter.

Timeline:

00:00 - Jam 1 / 4x Rimshot modules mixed with the Hot Glue. No external FX
01:01 - Take 1 / Going through different modes, adding noise to VCF in
02:27 - Take 2 / FM radio into VCF in, Rimshot is triggered with the first LFO of the Modulator and CVF is modulated with the second LFO output
03:08 - Take 3 / Rimshot with VCF in Hi-Pass mode triggered and modulated with the Modulator
04:15 - Jam 2 / 4x Rimshot modules mixed with the Hot Glue. No external FX
04:57 - Take 4 / Another take with FM radio on the Rimshot VCF in
06:04 - Jam 3 / 4x Rimshot modules mixed with the Hot Glue. With some reverb form the Black Hole DSO on 2nd ant 4th rimshot"

"The Mutant Rimshot is an analog rimshot and clave percussion synthesis module inspired by analog drum machines of the past. Like the other Mutant Drums, the Rimshot is capable of going above and beyond vanilla sounds. Expressive CV options, an external input and a multi-mode analog filter let you create unique percussion sounds in your modular synthesizer.

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."
