Demonstration of the Erthenvar Patch Chord Eurorack module available at erthenvar.com. Functionally, the module is somewhere between an oscillator and a waveshaper – and also can be described as a bank of two octaves of oscillator controlled oscillators
The Erthenvar Patch Chord is a bank of 25 “Oscillator Controlled Oscillators”, which can be used to generate chords in a Eurorack system.
The Patch Chord continously samples the cycle duration and duty cycle of the input waveform. It outputs 12 semitone steps above the input note, 12 semitone steps below the input note, and the root note itself (available from two output jacks). All outputs are pulse waveforms with continuously variable pulse width.
An oversized tri-color LED spans the color spectrum in each octave, so each note has a unique color! The input jack is passively multipled to an output jack so the visual effects of the LED can be had even if the module is not part of the current patch.
There four modulation types available, each with an input jack and a three-position switch. The switch can turn off the modulation, allow the CV value to control the parameter, or turn on the modulation. The modulation jacks are all DC coupled and respond to audio rate signals, though the tracked waveform has a lower limit of around 20 seconds per cycle.
- The SQR modulation forces the tracked duty cycle to 50%, making all of the 25 outputs into square waves
- The INT modulation changes the relationship between each output from a semitone step to an integer or harmonic step
- The ZERO modulation resets all of the output counters to 0, similar to a sync function
- The HOLD modulation stops tracking the input and keeps the last counted cycle duration and duty cycle values

Studiologic, mainly known for their controller keyboards previously, have released their first synthesizer, the Sledge. The Sledge is a 3 oscillator virtual analog synth that includes not only the standard analog waveforms, but a full set of wavetables from the PPG Wave. Also includes a Waldorf-modelled multimode filter, selectable white and pink noise, hard sync, an arpeggiator, fast envelopes, and a basic selection of effects. For many synthesizer enthusiasts, it is the particular interaction of the sound engine and user interface that makes a great instrument. A quick look at Sledge shows you the generous set of controls available to interact directly with the sound engine. When you touch the knobs and switches of the front panel, you will instantly be aware of the meticulous attention to detail our engineers have refined, during many decades building the best electronic keyboards.
You will experience the logical set-up of the synthesizer modules, mirroring the signal flow of a classic analogue synthesizer. But what really distinguishes any synthesizer is its sound. Fortunately, our friends at Waldorf Music have happily shared their experience and know-how on this crucial part of the Sledge Synthesizer.

Background info: This is first short intro vid for the new Macbeth X-Series Modules in 3U- more to follow- but I like the slightly heavy feel to this! You are basically listening to one oscillator triggering two dual EGs sweeping the the dual SV filter- so it’s one filter module that you are hearing!
Available from Analogue Haven and Schneidersladen very shortly!
The Pure-Pone Synthesizer is a virtual analog synthesizer. FM, SYNC and RING modulation in connection with the super wave oscillator gives a phat basic sound.
2 x modulations matrix, a 12/24dB multimode Filter and a delay / chorus unit works for sound design.
Free version with one voice. That is the only limitation.

Dreamboat fed a sample a hold CV
The Dreamboat is a dual chaotic oscillator with 2x CV inputs, a Gate output with adjustable threshold, and two sets of X and Y outputs. There are two oscillator sections to the module, the top half is an audio rate chaotic oscillator and the lower half outputs LFO rate signals. With its five outputs, the Dreamboat allows you to connect to plenty of modules all at once, allowing all kinds of modulation and listening possibilities.When used with an oscilloscope or a scope program in X/Y mode, the Dreamboat allows you to view its chaotic attractors in realtime.
Allowing for unique rhythms through the use of the gate output, a typical setup might see the Dreamboat involved in a few feedback loops while controlling an ADSR and a VCA with its gate output. When used with TIP-TOP’s special dual cables, hearing AND viewing the Dreamboat at the same time is a snap.
The Dreamboat is easy to use, just turn the knobs until the Chaos starts, then add modulation, cross-couple the two sections, and bring in a VCO or Noise module. For even more far out sounds, we recommend the use of two or even three Dreamboats for a truly powerful setup. Though the Dreamboat is not an oscillator in a way you might be used to, it will push you into new musical directions.
From subtle to destructive, from scary to absurd, the Dreamboat is a strange bird.
Use the Dreamboat to create everything from strange fogs to banging pots and pans, use it to explore Chaos or simply to have a truly unique module in your setup.
Snazzy FX recommends Gleick’s classic book CHAOS for those who want to know a bit more about what is going on behind the scenes in this module.
DREAMBOAT DEMO #1–CV/SCALE controls…GATE/Thrshld
Dan from Snazzy FX gave us a look at the Dual Chaotic Oscillator, which is a complex modulation module in Eurorck format.
The WMD Gamma Wave Source is a dual digital wavetable VCO that can create millions of timbres using onboard digital “effects”.
1V/Oct – Pitch input, used with standard 1 Volt per Octave keyboards and MIDI-CV converters. 0-5 volt input.
Pitch 1 & 2 – Controls the relative pitch per channel.
WT 1 & 2 Select – Select the desired wave table from the chart. 256 are available, each producing a different sound. Click for the table chart.
Out 1 & 2- Oscilator section output, each puts out +-2.5V/ 5Vpp signal.
The Effects Section
The GWS has four effects pipelines. Two for each oscilator. The Routing table selects how the oscillators interact with the effects pipelines.
FX Select Knob – Pushing this knob in will select the column that the knob is adjusting. Turning it will adjust the LEDs in the select column and will alter the Routing or Effects selection.
FX Para 1 & 2 – These knobs control the FX parameter for the oscillator section. Each effect has a specific parameter that is controlled by this knob. Adujust to taste.
Para CV & Attenuation Knob – This is a CV input for modulating and controlling the effects on the oscillator. Press the WaveTable Select knob to activate CV control per oscillator section. The LED will light when CV control is active. The FX Para knob will adjust the center or edges of the CV control depending on the selected effect.
Effects Table – These are the available effects, they are all created mathematically using 8 bit processing. The result is generally lo-fi and edgy, but smooth fat sounds are also possible.

Here’s a little Kraftwerk-like jam showcasing the WMD Gamma Wave Source wavetable oscillator module.
Our TR-909 Rim Out is clocking the Kilpatrick K4815 Pattern Generator and one side of a Livewire Dual Bissell Generator as a simple Attack/Decay envelope generator.
The pitch CV of the K4815 is running to the other side of the Dual-Bissel, using it to generate portamento. This is much more fun than your typical portamento as you have control of up and down glide rates.
The new Critter and Guitari Pocket Piano GR is being played using its new mono glide mode, which sounds really nice!
For filters on the Gamma we’re using a Division 6 Filtaire, modulated by the Livewire Vulcan’s sinewave, and a Metasonix R-54. We’re also using a Metasonix r-51 as our VCA and the Flight Of Harmony ‘Sound of Shadows’ karaoke delay.
Lots of modular goodies in this video :-). In case you are wondering what that wooden keyboard is -Tetrazzi is the newest incarnation of the Organus series, a mandala of analog oscillator circuits that can cross-modulate to form the empire of infinite circuitry known as pure sonic chaos. The tetrazzi boards shall be assembled by machine in Colorado, they will be perfect, and sonde-tested here in the workshop in Baltimore. All you need to complete it is four piezo barres, four bottons, four knobs, two output jacks, twelve studdes of brass, and a battery clip; all the hard stuff having already been done by a machine man!
