Not just another clone or continuation of the 808-esque, acid-style kicks of the Mutant Bassdrum – the Mutant BD9 seeks to explore uncharted bassdrum territory by having an integrated sub-oscillator for maximal auditory obliteration.
MIX lets you blend between the SHELL and SNAPPY tones that make up the overall snare drum
turn up the DRIVE to get overdriven snare tones with intense harmonics. The purple LED indicates when the snare begins to overdrive
like the other Mutant Drums, signal levels have been normalized for modular level input and output (up to 20Vpp)
SHELL synthesizes the drum skins
analog bridged-t sinewave oscillators, for those organic-sounding tones we’ve come to love from the 808
TONE control blends between the two sinewaves of different frequency
SHELL PITCH lets you tune one of the sine waves, to change the pitch of your snare drum
SNAPPY adds some noise to the snare
an analog white noise generator feeds the SNAPPY circuit
an external input lets you patch any sound source you like into the SNAPPY generator
voltage control of SNAPPY decay
SNAPPY feeds into an analog selectable high-pass or band-pass filter
voltage control of filter cutoff frequency
when nothing is plugged into the cutoff CV input, the SNAPPY envelope OR the adjustable sinewave from the SHELL generator normalize through the CV attenuverter for cutoff CV. A jumper on the back of the module allows you to select which of these internal modulation signals are routed here
the filter has three resonance settings: classic 808 (low resonance), high resonance, and self-oscillation
bipolar attenuators (aka: ‘attenuverters’) on CV inputs

The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. But there are significant updated schematics to have the most out of your modular setup.
The Atlantis is heavily inspired by the architecture and sound of the classic Roland SH-101. It has always been one of our favorite synths and we really liked how the seemingly limited architecture allowed for all sorts of creative and musically useful sounds to be easily generated. Just like the 101, it is quick to dial in a beautifully rich bass and lead sounds but there is much more sonic territory to explore as well.
Modulation VCO: triangle core with Hard Sync and Link switch to connect pitch to primary
Primary VCO: triangle core with Hard Sync, Octave switches, Linear/Exp FM and PWM
Global modulation bus with four VCO waveforms, noise and S&H options
Cascaded 4-Pole multimode filter
Looping ADSR with range switch, manual gate, and external level (velocity) control.
Three position output clipping circuit
27 jacks for creative and complex patching options
Control your drum modules and trigger events on your modular from any MIDI sequencer!
If you want to use a MIDI sequencer to trigger events on your modular synthesizer (e.g. using the hexinverter.net Mutant drums range or Tiptop Audio classical drum modules or envelope generators to control VCAs), Erica Synths MIDI to trigger module is just what you need; it converts ANY MIDI notes to eight 10ms Trigger signals. When designing the module, we put usability as priority; it will take you seconds to program the module. It works with any MIDI sequencer & controller so there is no need to change MIDI controller settings, instead, you reprogram the module.
