Polyphonic Euroracks?

Here’s another new polyphonic Eurorack module.

This one resolves the “how do you control polyphony in Eurorack” question in a different manner – it’s more of a self-generative approach. Each of its wavetable oscillator voices has a sequencer, an envelope generator, and VCA. At least it’s got a fair amount of CV control.

Detail seems a little sketchy still, but it sounds good to me.

There is an article in SynthAnatomy on it.

JoMoX Mod FM

Specifications

  • 8 voices fully multi timbral FM synth
  • 4 operators per voice
  • Full modulation matrix / 26 algorithms
  • 2 LFO/VCOs per voice
  • CV/Gate per voice
  • CV modulation inputs per operator
  • Outputs for each voice plus mix out
  • True audio FM modulation inputs
  • True analog filters per voice
  • 24db low pass
  • 12dB multimode LP/BP/HP cont. shape
  • True analog VCAs per voice
  • Midi TRS type A
  • USB C device
  • Digital reverb, 2x stereo delay
  • Full storeability, also CV amounts
  • 128 presets, 118 multi sets
  • 2x 128x64px OLED displays

This thing sounds great, to my ears, perhaps the analog filters ? Listen to the audio demos at the JoMoX site. More detail there too.

Neuzeit Warp

Specifications :

Main functions

  • Complete synthesizer with 4 voices and 2 oscillators each
  • Innovative hybrid of additive and wavetable synthesis
  • Four voice polyphonic with WarpEx Expander, monophonic as standalone unit
  • MPE and MIDI capable with WarpEx Expander, but also playable polyphonic with 4x CV & Gate
  • Comes factory equipped with numerous Factory- and Artist-Created features
  • Large pots act as performance-oriented macro controls for several internal parameters
  • Each pot has its own CV input
  • Graphically appealing, animated and easy to follow menu
  • Internal modulation: 2x ADSR, Note-Key and 2x LFO with a variety of waveforms
  • External modulation: OMNI CV input (24-bit), MIDI velocity, MIDI aftertouch, MIDI CC
  • Powerful and clearly animated modulation matrix with 8 x 19 = 152 internal modulation values per voice
  • Many modulation destinations can be modulated at up to 24kHz, a unique feature in digital synthesizers
  • The XY matrix serves as a pool of 32 x 16 overtone spectra from which each voice draws its basic sound
  • X and Y position to scan overtone spectra in two dimensions (with interpolation), as in wavetable synths
  • Complex spectral filter is applied to overtone spectrum before wavetable is calculated in real time
  • A mix of wavetable effects changes the waveform in the time domain: Fold, Drive, Bend and Redux
  • The waveform is used by two oscillators per voice, which can interact through several effects
  • Oscillator effects: Linear detune, Sync, AM, FM, Phase distortion, filtered noise
  • Low-pass and high-pass filters with 12 or 24dB per octave as well as filter resonance
  • Two outputs for stereo or two signal busses. 24 bit, 48kHz output, 32 bit internal
  • Pitch adjustment with stepped encoder in octaves, semitones or fine tuning. Quick reset on long-press
  • Several intuitive editors on board to draw your own overtone spectra or derive them from audio files
  • Wavetable export function to create wavetable files in the appropriate target format for other synthesizers

Needs the expansion module to give it full polyphony and MPE control.

This sounds pretty special to me. See my post for Machina Bristronica, which also has a sound demo video.
