video upload by Stazma and Nekyia Circuits

"More infos and affiliate links in the description // Support on Patreon to get samples from this session: / stazma

Today we are going to check out Ceremony by Nekyia Circuits. It's filter inspired by Rob Hordijk's Twin Peak resonator module.

It's a very resonant Low Pass / Dual Bandpass with many internal feedback routings that easily create vocal like sounds and wet and weird analogue bubblebaths.

Self-oscillating patching technics with Itinera

video upload by Stazma and Euterpe Synth Lab

"It can create fat and instable tones on it's own but it shine when used with any type of input signal that gets filtered at the same time. "Filtering Oscillator" like the manual calls it.
From "polyphonic" lead saturation to bass line synth generation over a drum beat."

2 patches with the Voltage Multistage 16

video upload by Stazma

"As i'm still working on a big demo for this beast but will still take some time I thought I would share two unusual sequencer patches with the Verbos Multistage 16.

It will also be a good opportunity to talk about the other modules, how I like to patch them, show of a few patches to demonstrate how all this can sound.

Have fun!!!"

3. Hello Alchemist ! Bastl Citadel synth engine rave to experimental - Stazma and Bastl Instruments

Alchemist is now EURORACK... into the CITADEL!!!!!
So here we go checking out how this synth engine will play out with his other citadel friend the Wave Bard in breakbeat torture mode.
Also a cool oportunity to play around the Diktaat from Mzourack to trigger both units in a performative way.

Citadel Alchemist is a patchable hybrid-synthesis based eurorack module that empowers you in discovering melodies and even harmonies despite being monophonic.
Patch programmable sequencing via the control signals into the two PITCH MOD inputs opens up a world of melodic inspiration beyond classic arpeggios while staying in your preferred SCALE.

5 synthesis modes
The Alchemist has a carefully tuned wide timbral range spanning across 5 synthesis modes (FILTER, FM, HYPERSINE, SUPERSAW and GLITCHNOISE) accessed by main TIMBRE sweep that is refined by the RATIO control.

The ENV macro knob affects different parts of the synth and sequencing engine to maximize musicality and it even lets you continually morph between the synthesis modes and access truly unique sounds.
The timbral palette is further extended by the dual FX section which offers either a wide delay that will smear the arpeggios into echoed harmonies or a chorus-flanger-distortion-combfilter macro custom tuned for each synth mode.
You can also access gliding rubber textures with the PITCH SLIDE macro that applies pitch envelope and portamento.
You can customize its rhythms and scales with the web-based editor.
Modulate anything
All main parameters can be modulated and tightly sequenced by the surprisingly powerful CV and GATE pattern generator. Create groovy off-grid beats using the built-in LFO, which can be synced, reset, or left to run freely.

BTFLD ... IN STEREO

video upload by SCHLAPPI ENGINEERING and Stazma

"Schlappy Patching 2026 EP.1

Hey there!
Today I'll have a go at using two BTFLD for stereo sound processing and show some modulation strategy to make it sound even MORE stereo. It's quite crazy all the weird and harsh tones you can get out of it feeding just a simple triangle wave to it.

We are excited to introduce our brand new reverb/echo plugin: Valhalla FutureVerb™!

FutureVerb was designed from the ground up to give you the most transparent and realistic reverbs we’ve ever made. 8 years of research and development have gone into creating new and innovative algorithmic reverb topologies. The FutureVerb reverb modes are as close to perfect as we have ever heard.

And, since we don’t actually believe in perfection, we added a colorful and powerful Echo section that can add color and warmth, or keep things as clean as you wanna be.

With 8 original Reverb modes and 12 flexible Echo modes, FutureVerb gives you the sonic power you need to create your own future."

"This was the very first patch I did when I got the Drummertime in the studio (30 minutes ago hahaha). I just played around and that's the result. Bass triggered by the accent, drums from the amazing 6mod6 also by @tubbutec and @lpzwmodules

You can connect these two with special cable on the back so you don't have to use patch chords but well I was in a hurry and wanted to jam ;-)

More infos about the Drummertime & Tubbutec here: https://tubbutec.de/drummertime/

Have fun!!!!"

"Bastl CITADEL - Fortress of Modular Magic - is a Eurorack reimagination of the popular Kastle 2 semi-modular desktop device. The CITADEL comes with a full 3.5mm patch bay that offers the flexibility needed in the Eurorack format while maintaining the strengths of the Kastle 2 allowing it to stand on its own, and yet let it truly shine when patched with other modules. We’ve also added switches
for hands-on control of the pattern generator. The Citadel provides the basic infrastructure needed to integrate Eurorack systems within the context of electronic music making: headphone output, TRS MIDI input and sync, tempo generator with divider/multiplier, USB MIDI (from the back of the module), stereo mixing, integrated LFO and Pattern generator and effects. All that makes it the perfect module for smaller and beginner systems while the fun and unique creativity of the Kastle 2 firmwares:
the FX WIZARD multi-effect processor and WAVE BARD sample player will earn its place in
larger setups.

🛠️ Get Wave Bard & FX Wizard at the same time 🔃
The Citadel comes equipped with a reversible front panel with WAVE BARD on one side
and FX WIZARD on the other side. It also comes with our custom designed tool to make
the panel switching as seamless as possible. You can load and try different Citadel/Kastle 2
present and future firmwares and updates with a USB port (on the back).

The Citadel might break a few rules of standard Eurorack design, but it does so in the name
of instant musicality, fun, and effortless integration of Eurorack with other gear. The PITCH
inputs on the WAVE BARD track 1V/Oct, are factory-calibrated, and there’s even dedicated
calibration software to ensure a perfect match with your source."
