Used Erwik Musikelektronik Voltage Controlled Multimode Filter - 1 of 12



via CONTROL.

This appears to be the first one to be featured on the site. Apparently only 12 were ever manufacturered, however, Doepfer's A-107 is based on it.

[Side note: CONTROl is also having a holiday sale on new items. Enter HOLIDAY10 for 10% OFF. The Erwik Musikelektronik is used so it does not qualify. Just sharing for those interested.]

Details on the Erwik Musikelektronik Voltage Controlled Multimode Filter follow:

"Based on the filter used in the Oberheim Matrix 12 and Xpander.

This Matrix 12 filter is a limited edition module, with only 12 filters produced by Jesper Johansson (ERWIK) in Sweden. It was produced in the end of the 90s.

Features:

2 Audio inputs. 2 VCA´s adjusting the input signals (manual or with CV). Filter "cutoff" and "Q" controllable manual or with CV. 1 VCA controlling the output signal (manual or with CV). Filtertype can be selected manual or with trigger at input "UP" & "DOWN".

Meet DOTS - An open hardware, open source DIY eurorack module


video upload by Johannes

"DIY eurorack module web teaser
www.d-o-t-s.net
https://github.com/johannesstrueber/dots"



From the manual:

The module features six outputs and two inputs. Each output is numbered from 1 to 6 and is accompanied by an LED dot that indicates the current state of the output. The inputs consist of a Clock input, which receives clock signals and triggers specific actions, and a CV input, which functions as a trigger for various control voltage signals. When a clock signal is detected, the corresponding LED will light up red. When an output is active the corresponding dot will light up white. You need to save all settings in the CONFIG menu.

The primary navigation tool is the rotary encoder, which allows you to toggle between different states and menus by pressing it. The module includes a potentiometer labeled Range, which is used to adjust a delay parameter.

Sequencer

In the sequencer program menu. You see a matrix of six channels (rows) by 16 steps (columns). Each channel can be toggled on or off by pressing the encoder. The current step is indicated by a white dot. The sequencer can be started and stopped by pressing the encoder. You can access the sequencer settings by scrolling the first element left or the last element right.

Random Trigger/Gates

The Random trigger program allows you to set a probability for each channel to trigger. The probability is set by the range potentiometer. The probability is displayed as a bar graph. The program can be set to trigger all channels at once or in a sequence.

Clock Divider

The clock divider program allows you to divide the incoming clock signal by a factor. Each circle represents one channel. If filled it will trigger the output. The divider can be set to a specific number or a mode like power of 2, prime numbers, or fibonacci numbers.

ETI International 4600 Vintage Semi-Modular Synthesizer

Note: Auction links are affiliate links for which the site may be compensated.


via this listing

"This is a large semi-modular synthesizer, designed in Australia and released as a kit by Electronics Today International magazine in 1973. The large aluminium panel pivots forward for maintenance. Its 22x22 matrix switchboard, joystick, complex modulation and feature set is reminsicent of a larger EMS VCS3, a comparison enhanced by the use of genuine Cliff "little Dalek" knobs.

The main modules in the 4600 design were repackaged for the (smaller) ETI 3600 and the lightly larger Maplin 5600 kit synthesizers. Its notable features are volts-per-herz VCOS (rather than volts-per-Octave linear VCOs), complex Transient Generators that are like simple three stage sequencers, and a different-sounding VCF.

This is a rare, powerful and unique synthesizer that needs some TLC from a competent builder to unlock its potential.

STORY

In the early 80s before it had been completely built, it suffered damage (the plaster ceiling collapsed on it, because of a shoddy repair job after the previous tenants, a punk gang, had a "demolition party" that destroyed all internal walls). The keyboard was destroyed and there seemed little reason to replace it (the first 4600 keyboard circuitry was problematic and had been replaced by a design from the Fairlight team.) There was some scratches to the case and a lot of dust, though the pots did not seem scratchy.

Playlist:

1. Bristronica 24: MyVolts The Silent Alchemist Nears Shipping
We caught up with Caroline who gave us the latest update to the *Silent Alchemist*, a versatile power hub designed for musicians. Featuring five isolated USB-C outputs and a high-wattage sixth output capable of delivering 100 watts, the device can power a Mac with the remaining outputs providing 20 watts each. Its independent circuits ensure noise-free operation, catering to a variety of devices including the Dreadbox module and Sysmo slope generator.

The Silent Alchemist uses innovative step-up power tips to convert USB-C input to the correct voltage for various devices. There's also new feature: an uninterruptible power supply allowing seamless transition between wall and power bank sources. Also introduced were updated cables, such as silver candy cords and floating ring TRS to TS cables, expanding connection flexibility. The Silent Alchemist is expected to be available in December with a competitive pricing strategy.

2. Bristronica 24: Circuit Happy ML2M Clock Sync module updates
At Bristronica 2024, we caught up with the creator of the *ML2M*, who introduced us to the latest version. The ML2M is a compact Eurorack module with Wi-Fi capabilities, allowing seamless synchronization with Ableton Live, Bitwig Studio, and iOS music apps using Ableton Link without the need for cables. It either connects to an existing network or creates its own, ensuring robust sync even in environments with unreliable Wi-Fi. The module, which retains its 2HP size, now features MIDI integration through TRS jacks. Users can access a web interface to configure each output for different clock divisions and reset triggers, making setup straightforward and flexible.

Alongside the ML2M, there's also the Missing Link Junior. This desktop version offers the same functionality but in a box format, complete with MIDI and CV clock outputs. Both products are now accessible, with a starting price of $250.
3. Bristronica 24: Archaea Exchange Patching Module
At Machina Bristronica 2024, we caught up with Arran from ‪@archaea_modular_synthesis‬ who presented the *Exchange Module*. This programmable patcher, a year in the making, evolved from its early prototype stage to a fully functional module. Arran explained how the Exchange can route synth voices via a beam controller and three exchange modules installed within the skiff, allowing for versatile patching. Operating like a matrix patchbay, it enables users to select inputs and outputs with the push of a button, create presets, and chain multiple modules for synchronized patching.

Communication between the modules occurs over the Eurorack power bus as well as over MIDI via the USB-C connection. The Exchange maintains analog integrity, ensuring there’s no conversion latency. The forthcoming release expected in late November 2024, includes a USB-driven editor for enhanced control capabilities.

Molten Bypass | By Molten Modular and Befaco


video upload by Cinematic Laboratory

"I really love it when the YouTube creators work together with manufacturers to realize modules we may all need, but can't get. Following in DivKid's footsteps, Robin from Molten Modular now presents his second Befaco collab after the Motion Meter. The Bypass is - you may have guessed it - a 'detour' circuit. Typical usage is hard-switching between a dry sound and an FX chain. It seems a bit similar to send/return, but the Bypass opens and closes an entirely different path. It's more like an insert/return, with a Launch button to open and close it (also CV controlled). When the Launch is set to 'soft', the return remains engaged, and only the insert goes on/off.

Even though on paper it's a simple utility with four ins and four outs, it opens up a lot of possibilities which are relatively simple to patch with separates, but you may need a switch matrix or something much bigger than just 4HP.

00:00 Less hard
00:43 Hard vs Soft switching
02:13 Rhythmic CV injection
02:55 Typical usage of FX insert/return
03:52 Feedback patching made 'less hard'."

Are A.I. Generated DX7 Sounds Good? Digital God or RoboBozo?


video upload by Off The Matrix

"There's a lot of hype and anxiety over the development of A.I. The A.I. generated DX7 sounds expose the limitations. Much of the hype is fueled by a childish want for new toys without a maturity of developing skills of tools one already has. In the terms of Steve Jobs, it's creation of B and C players.

Melbourne Instruments DELIA // It's got motorised faders!


video upload by Starsky Carr

"From Superbooth 2024 DELIA is Melburne Instruments latest synth. The Nina was a desktop fuly analog synth, this one is a hybrid with keys.

Just a quick demo from Superbooth, but if I can get my hands on one :).

FYI I spoke with Signal Sounds - the distributor - while I was there so hopefully we can sort something soon."



Additional details and pics via Melbourne Instruments:

Motorized Morphing Polyphonic Synthesizer

49 Key Velocity and Aftertouch Sensitive
DELIA is a bi-timbral polysynth inspired by the motorized control panel and voice architecture of the original Melbourne Instruments’ Nina. Delia introduces a 49-key velocity and aftertouch sensitive keyboard, new multi-mode analog filters, high pass and low pass resonance control, 3-stage overdrive, and even more modulation possibilities.

Analog soul with a computerized brain

Using a combination of true analog filters and virtual analog modelling, DELIA retains the vital sound of massively overdriveable analog ladder filters, while using a digital front end to run modelled VCOs, wavetables, high pass filters and more. The powerful combination of analog plus digital is harnessed by Delia’s unique 12 note mode, using 12 complete oscillator banks into the 6 filters, limiting note stealing without compromising the sound, and fully unleashing Delia’s bi-timbral operation.

Discrete Multi-mode Filters

DELIA’s true analog low pass filter is the heart and soul of the sound engine — warm, full and sweet or fearfully aggressive. It is complemented with a high-pass modelled ladder filter, which can be linked for bandpass and notch operation. With 12 and 24dB slopes and separate high/low pass resonance control there is huge scope when shaping sounds, from the most delicate plucks and pads to the wildest overdriven bass and lead sounds imaginable. Delia is an inspiring creative companion and dependable instrument for musicians and composers, no matter what their level.

Know your Filters! Analog + Digital

DELIA’s filters have an analog and a digital section per voice. The analog filter is the classic discrete transistor ladder filter offering a choice of 24dB or 12dB per octave operation. Prior to this filter is an analog variable overdrive circuit that can push the filter from normal operation to complete distorted collapse of the transistor ladder, adding richness, aggression and body to your sound.

The HP filter is a digital transistor-level mathematical model of a 24dB ladder filter, based on the gold-standard Ebers-Moll transistor equations. This gives an almost perfect match to the response of the analog circuit, including the overdrive response, resonance and natural filter frequency variations.

The High Pass filter is less important sonically, so the choice of digital instead of analog reduces cost without compromise. Having the Low Pass filter second gives true analog character where it counts.

The filter is Multi-mode with 3 ways to configure. The High Pass and Low Pass cut-off frequencies are separately controlled with 2 knobs, so the overall operation can be High Pass, Low Pass or Bandpass. The separate HP and LP resonance controls offer flexibility to shape the sound including vocal-style formants. Delia’s LINK function locks the distance between the Low Pass and High pass knobs, setting a constant width Bandpass for both manual control and sweeps using the VCF envelope or other Modulation Matrix controls.

Total Recall. It’s not a dream!

The motorized journey does not end at Recall and Morph; Delia’s ‘MOD Mode’ automates the Modulation Matrix setup. As you move between the 20 modulation sources, every knob changes position to display its modulation amount. No need to tweak the panel every time you switch sources or destinations, no matter how many modulations or slots are active. Delia gives you a sound design workflow that truly flows - combining the flexibility of a soft synth with the tactile experience of a classic hardware synth.

Morph every parameter, then Mod it!

DELIA’s A/B Morph function lets you explore and sweep through timbres like no other. The A/B Morph sound is an actively calculated change in parameters between the A and B patches including the entire modulation matrix. This provides the ability to instantly create a new preset based on the Morph position that is neither the A or B patch, but instead a totally new sound. Morph is also a ‘MOD destination’, giving you even more creative control via Aftertouch, Mod Wheel and Expression.

Step into an infinite matrix of sound

The motorized journey does not end at Recall and Morph! Just like Nina, Delia’s ‘MOD Mode’ automates the Modulation Matrix setup. As you move between the 20 modulation sources, every knob changes position to display its modulation amount. No need to tweak the panel every time you switch sources or destinations, no matter how many modulations or slots are active. Delia gives you a sound design workflow that truly flows - combining the flexibility of a soft synth with the tactile experience of a classic hardware synth.

Building on innovation

DELIA inherits many of the acclaimed features of Nina, including 4-Quadrant Analog VCAs, Morphing, Digital Effects and Digital Wavetable Oscillator. Adding to these features are the inclusion of Sequencer Phrase Looping and Overdubbing, and the ability to assign your favorite effects parameter to the Effects Macro control.

Under the hood Delia is a beast! Virtual Analog Oscillators model Nina’s discrete circuitry but add cross-modulation, and Delia’s 20 modulation sources and 40+ mod destinations with unlimited slots gives sound designers an almost endless spectrum of sounds. Two digital effects processors paired with classic effects presets and the option to run in series or parallel offers creative freedom. And with the ability to save more than 16,000 presets inspiration and artistry will never be limited by available memory or slots

Waveform, Envelope and Wavetable Visualizers

Delia’s high definition LCD also provides useful Waveform and Wavetable visualizers, as well as instant feedback and display for almost every function as you interact with the control panel.
