Reticulum Versio vs Soma Cosmos

video upload by John Schussler

"The Soma Cosmos 'Drifting Memory Station' is unfortunately only available as a very large pedal unit. I've been on the lookout for a Eurorack module that could do the same thing, and found a firmware called 'Reticulum Versio' (created independently of Noise Engineering) that replicates much of the Cosmos functionality.

Now that I have both, I figured I'd try them out next to each other and see how they compare. The Cosmos has a few more features and control, which is to be expected since it's got more real estate to work with, but the Reticulum captures the core of Cosmos.

Many thanks to Ohnoabear (from ModWiggler) for his Reticulum firmware, and for sharing it with the community.

just look at the past (Yamaha YM2151 + Yamaha YMZ280B)

video upload by Vivi The Pumpkin King

Fun video featuring the Yamaha YM2151 + Yamaha YMZ280B voice chips. Interstingly, you'll find previous posts mentioning the YM2151, but not the YMZ280B. This simply implies the YM2151 is more comonly used in DIY projects.

"The Yamaha YM2151, also known as OPM (FM Operator Type-M), is an 8-channel, 4-operator sound chip used for frequency modulation (FM) synthesis in 1980s arcade games, home computers, and synthesizers."

Key Features

Voices:

Plays up to 8 simultaneous sounds or channels.

Data Formats: Supports 4-bit ADPCM, 8-bit PCM, and 16-bit PCM waveform data.

Memory: Connects to up to 16 MB of external ROM or SRAM for storing sound data.

Output: Delivers stereo output with 4-bit/16-level panning for each individual voice.P

rocessors: Links with an external digital-to-analog converter (DAC) and can connect to a Yamaha YSS225 effects processor for extra channel processing."

"The Yamaha YMZ280B, also called PCMD8, is an 8-channel PCM and ADPCM sample-based sound chip made by Yamaha Corporation in the mid-to-late 1990s.

Key FeaturesChannels and Operators:

It supports 8 simultaneous channels of 8-note polyphony with 4 operators per channel.

Sound Generation: It includes built-in noise generators, LFOs for vibrato and amplitude modulation, and timer circuits.

Companion IC: It requires an external digital-to-analog converter (typically the Yamaha YM3012) to output stereo audio.

Common Uses

Arcade Machines: Atari's Marble Madness (1984) was the first arcade game to use the YM2151 for FM synthesis, leading to widespread adoption in arcade hardware.

Home Computers: It powered the sound boards in sharp computers like the Sharp X68000 and the Yamaha CX5M music computer.

Synthesizers: Yamaha utilized the chip in early budget keyboards and sound modules like the DX21, DX27, and DX100."

Minimal Audio Current 50 Atmospheric Arp Presets. Sound Demo

video upload by Anton Anru

✨ "Dreaming Motion" is a bank of 50 Arp Presets for Minimal Audio Current 2, combining warm analog-inspired sounds with soft and airy atmospheres.
The collection moves between retro synth character, subtle analog imperfections, dreamy textures, and spacious evolving arpeggios, giving the bank both nostalgic and modern sides.

📦 The download link: https://antonanru.sellfy.store/p/curr...
👤 The author of the soundset is Ilian.

🎛️ Each preset features 4 Macros for shaping the sound, while the Modwheel adds additional movement and expression.
The macros are a significant part of the soundset. They can change tone, stereo width, modulation depth and rate, noise level, distortion, detuning, space/echo/reverb, effects mix, envelope parameters, and others.
You may control them via MIDI controller, use them for automation, or map the macros to your DAW modulators like LFO, Shaper, and others.

📻 The patches are perfect for Electronica, Synthwave, Ambient, IDM, Downtempo, Melodic Techno, Chillout, and experimental electronic music.

🎹 All Arps are designed in either C Major or C Minor, following Current 2’s tonal Arp system. This makes the presets easy to use while keeping their harmonic character consistent. You can change the Scale in the lower right corner of the synthesizer to the one used in your track.

JHaible TAU Phaser 'The Pipe' 2026 by Random*Source

video upload by Cinematic Laboratory

"Today I am proud to show off the new TAU 2026 phaser edition from JHaible x Random*Source for Eurorack. Obviously the core 'Pipe' sound didn't change because it needs to remain faithful to its history and heritage. It's not supposed to sound different from the previous R*S version. But it does. This is because the TAU '26 features two inputs and two CV inputs instead of one. Also the inverted (-) V/OCT is dropped. Visually, the panel now matches the Serge Modular line so it neatly blends in with your Serge 3U gear.

So is it a 20 pole- or an 18 pole phaser? Is it even important? No. What's truly important is the PIPE configuration of 20 transistors in a classic ladder topology. Your input will actually flow through the circuitry like air in a tube and I think it's absolutely stunning when you run noise through it. However, when you bring a lush pad, the TAU will redefine 'lush' into a pseudo stereo swirl that doesn't make you seasick.

When you crank up the feedback and hit it with some trigger 'stick' or chain, the TAU will make remarkable percussion. The Tau is also available in 4U. It's still a Haible, but it carries the 'Serge Modular' branding and comes with an extra mixing panel.

Diving deep into Doppler by Jasmine & Olive Trees, a Eurorack module that makes drums from any sound

video upload by Perceptes and Jasmine & Olive Trees

"In this video, we'll be diving deep into Doppler, a new Eurorack module from Jasmine & Olive Trees that can turn any sound source into a drum! Doppler also has an amazing new mechanism for changing firmware by simply placing an overlay panel on top of the module."

00:00 Meet Doppler 01:13 Patch previews 01:56 Automatic firmware switching 04:28 Module overview 06:18 Noise output 07:09 Kick drum sounds 09:16 Mod control 09:40 Chord mode 11:14 Doppler mode 12:13 FM mode 13:53 LPG (low pass gate) mode 14:57 Snare drum sounds 15:24 Hi-hat sounds 15:39 FM tom sounds 16:13 Chaotic textures 16:36 Full beat with Traffic 20:07 Glitchy percussion 22:49 Different transient sources 26:16 Speech sample as body input 29:44 Chord progression 32:52 Doppler jam

Includes Door, Rubin and Lichen overlays for free, the firmware is automatically swapped when placing an overlay on top of the modul.

Any sound source becomes percussion.

Feed an oscillator, a sample, or any audio signal into Doppler. It shapes it into a kick, a snare, a hi-hat, a percussion, or something else.

It morphs anything into everything. The best friend for Traffic & Prio.

All the processing moves across a continuous spectrum: from a clean signal, to a pitch envelope, into FM modulation for complex percussive textures.

Built on top of our J&OT DSP platform. Future family firmwares can be swapped for free using a simple USB cable and our J&OT web tool, no extra hardware required.

Highlights

Doppler kick engine: delay-line pitch sweep, five depths from –1 to –3 octaves

Harmonic FM: modulator tracks the spectral peak of your input, plus cross-mod chaos at the top

13 chord voicings: major, minor, sus, 6ths, 7ths, 9ths, 11ths via four pitch-shifted taps

Two inputs: Body (main signal) and Trans (transient channel with auto-tuned band-pass)

VCA / LPG modes: toggle via long-press, saved to memory

Independent noise output: dust oscillator whose density tracks input character

CV: on Attack, Decay, Mod, Amount

Smart Attack: noise decay to the left, or long swell to the right, all on one knob

Iridium Desktop MK2: The Next Sound Dimension

Iridium Desktop MK2 is a new generation of the highly acclaimed Iridium Desktop synthesizer introduced in 2020 by Waldorf Music, and since then used by countless artists and sound designers. After six years the time has come to advance the sonic success story even further.

Based on the legendary multi-engine design of the Quantum & Iridium product line, the MK2 innovates even further, thus fitting perfectly into Waldorf’s forward-looking synthesizer design philosophy.

The MK2 features a new and fresh design, and an improved CPU board with more RAM and flash storage allowing for more sample storage and opening a whole new world of synthesis capabilities.

Per-Note-Parameter-Locks
(ft. Aphex Twin)
Only on the MK2 you can enjoy a very special feature called Per-Note-Parameter-Locks which is the result of a collaboration with legendary Aphex Twin, a long-term Iridium Desktop user.

With this feature, each of the 128 notes can be assigned up to 16 individual parameter variations by simply holding a note and turning knobs. This system allows each note to have a different set of parameters. You can even change the synthesis mode of oscillators for each note or change effect parameters. It feels like adding a whole new dimension to your music. Per-Note-Parameter-Locks are saved with each patch and can be inspected and edited on a dedicated page.

Seeds – The Sixth Synthesis Sense
The added RAM further allows a new sixth synthesis method for each of the three oscillators. Inspired by wavetable synthesis, in which each wavetable represents a timbral journey, Waldorf has found a way to base these timbral journeys not only on static waveforms, but also to dynamically synthesize each waypoint from sub-oscillators we called “Seeds”. These can be controlled and recombined using techniques like ring modulation and frequency modulation, and enriched with noise and other non-pitched material. While we provide, similarly to wavetables, a set of predefined timbral journeys, you can also edit and create your own.

Protein’s “Flavour” Knob
The new knob called “Flavour” adds sonic liveliness using our new concept of micro-variations in timing, timbre, pitch, and a whole set of additional parameters we recently introduced with the Protein synthesizer.

More Memory, Layers & Sound
With the increased memory capacity, you can change the multi-timbral layer count from 2 to 4. In addition to layered and split modes, the new MK2 also features more advanced multi-timbral modes, such as round-robin and random-robin. These additions bring greater timbral richness and variety, letting you build deep and complex sonic landscapes. A dream come true for all sound designers, sonic explorers and cinematic artists!

Iridium & Quantum Update 4.0
A general update of the Iridium and Quantum operating system will be available soon.

Version 4.0 provides some of the new features for all existing Quantum and Iridium models like the Mutator patch randomizer introduced in the Microwave plugin, a new polyphonic arpeggiator, new microtonal features saved in patches and other features.

Connectivity
Stereo Audio Out: 2x TS jacks
Stereo Audio In: 2x TS jacks
Headphones TRS output with level control
DIN MIDI In, Out & Thru
USB Type B (device) for MIDI connection to computer

Yuyo cmos synth - First try Attiny85 dco with analog cmos shaping and twin t filter

video upload by JIANT

"everything is from the synth to the zoom recorder, twin t drums, xor snare, pt2399, and cmos stuff.

attiny85 reseting the phase of 40106 oscilators, the digital control accepts 1voct from keysetp and go to the 40106 inputs through resistors, a little rc for filtering the pwm, and for this reason when you change the oscillator frequency you can get intervals and crazy stuff. is not orthodox but suits my need for Rich timbres. the dco goes to 40106 buffers , and then 4040 dividers, twin t filters, one for each of the two voices, one goes to env, vca, filter, delay, and the other one to clock divider and filter, to get the sub osc.

firmware super simple only for checking the conversion from filtered frecuency of the attiny85 to my 40106 non exponencial vcos.
currently is tracking 10 octaves really good, the trick is put a voltage divider in the cv in of the attiny because keystep has 0 to 10v and the attiny accepts 0 to 5v tehn the tracking inside the attiny converts o.5v oct to 1 volt oct. i dont know anything about coding but i made it with chat gpt and my design . source code will be in the coments ."

Red Synton Syrinx Audio Demo

video upload by Edwin Kiddo

"Audio demo of my Synton Syrinx. This one has been serviced and the power input changed from 220 to 110V.

The Syrinx uses seven Curtis chips for its VCO's, VCF's and envelopes. It has two analog VCO's, a sub-oscillator and three flexible voltage-controlled filters. You can switch between the three filters for either a 24 dB lowpass, or two bandpass filters, and they can be patched in four different ways (series/parallel). Additionally the Syrinx has two LFO's, FM, PWM, osc-sync, 2 ADSR envelopes, ring modulation, portamento and a cool touch-pad that can control various parameters from pitch-bending to the LFO rate. The Syrinx's Mixer section lets you adjust levels for each VCO and the sub-osc as well as the Noise Generator and Ring Modulator. Unfortunately, being released around 1983, the Syrinx just missed out on MIDI and patch memory options.

Polyphony - Monophonic
Oscillators - 2 VCO's (tri, saw, square, PWM) plus 1 sub-oscillator, ring modulation and noise gen.
LFO - 2
Filter - 2 Bandpass filters (Peak 1 & 2) and 1 Lowpass 24dB/oct filter. Individual cutoff and resonance controls, ADSR Envelope, Keyboard Tracking and LFO modulation
