Malekko Heavy Industry Manther Growl
Analog Eurorack monosynth voice — CEM3340 VCO, SSM2044 VCF, dual ADSR.
26 HP Eurorack module
Manther Growl is the 26HP Eurorack version of Malekko's Manther tabletop monosynth. Built around a CEM3340 VCO IC and SSM2044 analog filter, it packs a complete monophonic synth voice into one module: oscillator with Square/Saw/Triangle level controls (each with individual outputs and CV inputs), wavefolder operating on Triangle alone or on the entire post-filter signal (TRI/ALL switch), 1V/oct input with FINE tuning, octave range switch (2'/4'/8'/16'), assignable LFO (4 shapes: ramp/sine/square/random) with a ramp-to-saw waveform switch and dedicated Pitch/PW/Cutoff attenuators, dual ADSR envelopes (one for VCA, one for Filter) with individual gate inputs and envelope outputs, external audio input routed to the filter, and CV inputs for filter frequency/resonance, VCA level, PWM, and waveform amplitudes. Manther Growl is a complete classic-sounding mono voice — patch a 1V/oct sequence into 1V/Oct, a gate into VCA Gate, and a master clock into the LFO for tempo-synced modulation.
Features
- 26HP, 34mm depth — generous panel real estate for live performance
- CEM3340 VCO IC — classic analog sound
- SSM2044 analog filter — coveted lowpass character
- Three direct VCO outputs (Square, Saw, Triangle/Shape)
- Three CV inputs for waveform levels (modulate the internal mix)
- Wavefolder with TRI/ALL switch — fold triangle only or all post-filter signals
- Octave range switch (2' / 4' / 8' / 16') plus FINE tuning
- 1V/oct pitch input with 4-5 octave tracking
- Internal LFO with 4 waveforms (ramp, sine, square, random) + ramp/saw secondary switch
- LFO assignment knobs for Pitch, Pulse Width and Filter Cutoff
- Direct LFO output for external modulation
- Pulse Width manual control + PWM CV input

How-To Guides
- First patch — patch a sequencer and trigger a basic voice
- Classic filter envelope pluck
- Aggressive wavefolded lead with ALL mode
- LFO vibrato + PWM modulation
- Use Manther Growl as an external filter/effects processor
- Self-oscillating filter as a sine voice
