Deftaudio Fidget Spinner Eurorack LFO DIY kit

video upload by DeftAudio

"Here is a simple to build fidget spinner kit for Eurorack to use as an LFO with other modules.

Deftaudio SpinnerLFO is a simple DIY kit based around a fidget spinner and a double bass pickup.

This module is fully passive and requires no external power. It can be used as an oscillator source, where the frequency is based on the rotational speed. To control other CV inputs, you need to amplify the signal coming from it, such as with a preamp built in Behringer 2600. Any other preamp, mixer and a guitar pedal will work too.

Assembly notes:

Assembling the kit is straight forward. You need very minimal soldering skills, just to solder the sockets and two wires together. No special tools required.

Introducing The Octopoid Sequencer ...

Many well known and famous rhythms can be related to Euclidean Patterns: Geometric patterns which are generated by a specific algorithm. They offer great opportunities to generate a broad spectrum of new and interesting rhythms and allow you to easily create fresh rhythms and grooves for your next music productions. Within just a few steps, complex and inspiring patterns can be created. Go for a dive with The Octopoid Sequencer and experience the creative world of Euclidean patterns …

Assume a full bar is split into a certain amount of beats, for example four beats. Next define the amount of active beats, let’s say two. Finally the algorithm decides which two of the total amount of four beats should be active. Just by playing with these two parameters you can already create a huge amount of inspiring rhythms. But The Octopoid Sequencers offers more …

By choosing odd-numbered or differing beats for each of the eight modules, rotating the patterns, changing playback speeds (x2, x4, …) for individual modules or by customizing and randomizing velocities / timings as well as using more variations, complex and interesting rhythms can be easily created which will lead to surprising new inspirations.

Beyond rhythms and grooves: Create melodic progressions by triggering chord notes! Different modes allow you to add variations, to manipulate melodies and to interact with The Octopoid Sequencer in real time. Ideal for live performances!

In Split Mode, all modules can play simultaneously or sequentially arranged in groups or even one after each other. This leads to more and longer melodic variations. Pitch all modules on the fly or trigger them using your external MIDI keyboard / DAW in Floating Pitch Mode.

Finally manage and backup your presets using the internal SD card. You can store up to 160 presets grouped in 10 banks, each with 16 slots.

Stereo Patch From Scratch with Panic Girl featuring XPO, Buchla 258t Dual Oscillator and the Touché

video upload by Perfect Circuit

"Eurorack modular synthesizers are embracing stereo sound in new ways—over the last few years, we've seen a ton of stereo-oriented modules come out from top brands like Make Noise, SSF, and plenty more!

In this video, Panic Girl walks us through a stereo patch on her personal system, featuring the Make Noise XPO, Mimeophon, and the Tiptop Buchla 258t Dual Oscillator. This mix of mono and stereo modules makes a great learning ground for getting into the stereo mindset—so grab some headphones, tune in, and space out!

Jen SM 2007 italian string machine 1979

video upload by ohm_studi_ohm

Update: now listed on Reverb.

"Here is a demo of a quite rare Jen SM 2007 string machine. Unit was fully serviced and is for sale. Get in touch if interested.

The SM 2007 is a very nice stringer for whomever like these classic sounds. Very compact and lightweight and still gifted with quite a number of features.
There are 3 strings sounds (cello, viola and violin) that can be individually mixed, variable attack and sustain, a tone control and of course a triple BBD chorus.
The later has 3 presets: ensemble, solo and organ that are basically different setting of the chorus effect, 'ensemble' being the full triple chorus, 'solo' uses only 2 of the choruses for a less dense sound and "organ" is the dry sound of the string sounds, thus enabling to use external fx with more flexibility.
"Auto sustain" switch makes it possible for sustain notes either to be cut when new ones are played or be left to release. And the sustain length can be massive !
Soundwise it is silky and lush, the closest I can think of is the Logan/Hohner string melody. A bit like Elka rhapsody too but denser since it has triple chorus, not a double one.

Recorded dry with no treatment."

And some pics. Note the stand is not original. Perfect fit though.

Transonic Trio: A Triple Transformation of Beats, Keys and Voice with the Make Noise Spectraphon


00:00 - Spectraphon meets Pulsar 23
01:41 - Spectraphon meets Orchestron
03:16 - Spectraphon meets Voice

The Make Noise Spectraphon can transform and reveal many a hidden world contained in all the sounds we make. Rather than present a breakdown of this wonderful module, I thought I'd hit you with a no talking special where I set the beast against drums, keys and voice to form a little Transonic Trio.

In the last track, all the vocal effects are coming from the Spectraphon :)"

Kawai K1 Patch Demo: Korg Trident Comparison

video upload by Off The Matrix

"This is demonstration of a few great Kawai K1 synthesizer patches created by Off The Matrix. Although the K1 is a inexpensive digital synth, it is capable of sounding as rich as an analog beast like the Korg Trident. The patches can found at the digital store linked below."

The New Yamaha DX7 Patches

video upload by Off The Matrix

"These banks showcase the true capability of the DX7. No more spending hours going through banks to find the right sound. The DX7 is a truly remarkable synth which can rival modern VL synths. The realism of many of the sounds comes from the 6 operators of the DX7 responding differently to velocity levels, so the sound is dynamic as an acoustic instrument. The patches go far beyond the "canned" samples sound of the ROMplers of the period. more If these patches came out in the 80's they my have changed history.
The sounds can be found at

The video effects were created with Pinnacle Studio 24"

What Does an Envelope Generator Do? (Modular Synth 101 | Part 5)

video upload by Musical Miscellany (Poorness Studios)

"We're up to episode 5 in this series. Today, I take a closer look at Envelope Generators. This is the component that makes a synthesizer sound more natural. Instead of just on/off, it produces a rising and falling voltage."

via this auction

"The Korg DVP-1 Digital Voice processor was released in the early 1980's. It consisted of a Vocoder with its own internal waveforms, a five part Harmonizer, a Pitch-shifter and an Internal Synth. The Vocoder is very intelligible. While the Harmonizer does not sound super realistic, it has its own unique effect. It has five polyphonic voices, four with chorus on, unison mode and 64 memory patches to store your settings."

Roland Analog Vocoder SVC-350 SN 212050

"A lot of paint peeling, rust, and stain on various parts of the main body exterior, the appearance is not good.

Operations have been confirmed, noise on volume and balance knobs but it works.

You will hear a 'rattle' sound of small objects rolling from the inside when you move the main unit."

UDO Super 6 and Rossum Eurorack Generative Ambient

video upload by riotbell

"This is a generative ambient piece made on the UDO Super 6 and a few Rossum modules. The Super 6 is supplying all of the oscillators while the Morpheus and the Mob of Emus are providing most of the modulation.

So far I have mixed feelings about the Super 6. It sounds undeniably gorgeous and it's a joy to program--until it isn't. Like most people, the buried secondary controls have left me somewhat perplexed on certain patches. Still shocked at how many lovely places it can go however.

Thanks for listening."
