Here comes the MARF - Tiptop Audio 248t Demo Video

video upload by Stazma and Tiptop Audio

"Here we are, the "MARF" aka Multiple Arbitrary Function Generator Model 248 in now in a reality in eurorack: all hail the 248t!

In this video I'm going to show you a bit of everything it can do (it can do a lot) but believe it or not I'm not going to go too deep. I'll try to go a bit deeper in some of the many rabbit hole of this things in future videos."

Deep dive into the PCO aka Precision Oscillator by Serge Modular

video upload by Stazma

"Today we check out the one of the most (seemingly) simple building block of the Serge Modular: the PCO aka Precision Oscillator.

This module does have some tricks up it's sleeve and is not as simple as it seem especialy, when it comes to it's sync behaviour, but overall it's a great sounding analog oscillator that is well... very precise hahaha.

This makes it ideal in this dual configuration to be used as a classic "carrier" / "modulator" configuration with itself and with other modules.

Have fun!"

Why to love the QXG by Make Noise

video upload by Stazma

"Today I'm happy to show you the new(ish) module from Make Noise: the QXG aka Quad Stereo Gate.

I've been a low pass gare addict since discovering them in Reaktor 6 and then throught my Eurorack addiction. My first one was the LxD so a new LPG by Make Noise is always something I love checking out (even tho I passed on the DXG). So today we'll talk about Low Pass Gate, check out how the QXG compare to some classic and available circuits from Make Noise such as the Optomix and LxDn and of course try out some different use case, both inside and outside the New Universal Synthesizer System.

Have fun!!!"

Today we are going to check outthe Voltage Multi Stage 16 by Verbos Electronics!
I've been a mega fan for years of the original Multi Stage (8 steps) released in 2014 and I was super happy to see this new bigger version with many upgrades such as the stage select inputs and revamped 'stage adress' mode.
I'll show you some cool patches with this thing and I hope you'll have fun.

There's been a lot of talk about technical issue with this module online and I'd like to report that mine works correctly. I got it from Verbos to do the video and I had some issue with the power of the Black Box case that was fixed very quickly. Other than that so far so good."

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.

1. CITADEL ALCHEMIST & Kastle 2+Citadel DIY Kits & more NEWS from Bastl!

We built a fantasy world of magical music machines with the FX Wizard multi-effect, the Wave Bard sample player and the Alchemist synth that live in battery powered Kastle 2 format and the Citadel eurorack version. We are excited to not only announce the late arrival of the Citadel Alchemist Eurorack module to the party, but to let everyone know that all the instruments are now available as DIY kits and that we are partially open-sourcing it so the world we started could be expanded by many others."

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

"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."
