“version 2, of my open source virtual modular.

this release aims to :

– bring orac to more musicians
– be easier to use
– be more flexible

in this video, I describe what’s change and demonstrate many of the new features.
Orac now runs not only on the Organelle (like 1.0), but also a Raspberry PI, and a couple of different Eurorack modules.

“I’m just about to release Orac 2.0 🙂

this short video is a quick demonstration about what Orac is, a taster of what it can do, and how you can use it.

for release: Ive got a what’s new for Orac 2.0 video, and also some tutorial videos on how to set it up etc.

I hope the video is not too confusing,
there is a lot of things going on , and frankly its

Build your own scratch DJ controller

If DJing originated in the creative miuse and appropriation of hardware, perhaps the next wave will come from DIYers inventing new approaches. No need to wait, anyway – you can try building this scratch controller yourself.

DJWORX has done some great ongoing coverage of Andy Tait aka Rasteri. You can read a complete overview of Andy’s SC1000, a Raspberry Pi-based project with metal touch platter:

Step aside portablism — the tiny SC1000 is here

In turn, there’s also that project’s cousin, the 7″ Portable Scratcher aka 7PS.

If you’re wondering what portablism is, that’s DJs carrying portable record players around. But maybe more to the point, if you can invent new gear that fits in a DJ booth, you can experiment with DJing in new ways. (Think how much current technique is really circumscribed by the feature set of CDJs, turntables, and fairly identical DJ software.)

Or to look at it another way, you can really treat the DJ device as a musical instrument – one you can still carry around easily.

The SC1000 in Rasteri’s capable hands is exciting just to behold:

Everything you need to build this yourself – or to discover the basis for other ideas – is up on GitHub:


This is not a beginner project. But it’s not overwhelmingly complicated, either. Basically…

Custom PCB
System-on-module (the brains of the operation)
SD card
Jog wheel with metal capacitive touch surface and magnet
Mini fader

Free software powers the actual DJing. (It’s based on xwax, open source Linux digital vinyl emulation, which we’ve seen as the basis of other DIY projects.)


You need to assemble the main PCB – there’s your soldering iron action.

And you’ll flash the firmware (which requires a PIC programmer), plus transfer the OS to SD card.

Assembly of the jog wheel and enclosure requires a little drilling and gluing

Other than that it’s a matter of testing and connection.

Build tutorial:

Full open source under a GPLv2 license. (Andy sort of left out the hardware license – this really sort of illustrates that GNU need a license that blankets both hardware and software, though that’s complex legally. There’s no copyright information on the hardware; to be fully open it needs something like a Creative Commons license on those elements of the designs. But that’s not a big deal.)

It looks really fantastic. I definitely want to try building one of these in Berlin – will team up and let you know how it goes.

This clearly isn’t for everyone. But the reason I mention going to custom hardware is, this means both that you can adapt your own technique to a particular instrument and you can modify the way the digital DJ tool responds if you so choose. It may take some time before we see that bear fruit, but it definitely holds some potential.

This granular convolver hardware is the latest creation from Tatsuya Takahashi

There’s a nice gift for Red Bull Music Academy attendees: a hardware convolver effect from the man who led the team at KORG that gave us volcas and minilogues. Here’s a sneak preview.

The Granular Convolver is a collaboration between Tatsuya, now working as an independent designer and relocated to Germany from Japan (while still in an advisory position with KORG), and Berlin’s own E-RM Erfindungsbüro, maker of obsessive-quality clock devices. (Founder Maximilian Rest is the design mind there.)

I’ve got one in-hand, and will detail its operation with some sound samples shortly, but here’s a quick teaser.

First, a Jony Ives (sorry)-style video from Tats:

The important thing: this Raspberry Pi-powered device feels amazing, like a heavyweight metal luxury item, and makes wonderful sounds.

The basic operation:

1. Record a sound snippet.
2. Play back that sound snippet via a granular engine.
3. Convolve that playback with a live input, combining the two sounds – the timbre of your original sound, the envelope of what you’re playing now.

There are also some features for storing and recalling presets, which make this performance friendly.

Why this matters: it gives you an expressive way of “playing” an effect, like an instrument.

And it’s a unique boutique hardware making project, for the particular context of an event – very different than the mass-manufactured designs of something like the volca series. The units were all hand-assembled (by Tats himself) here in Berlin, and even the boards and cases were made here, as well, so it really is a Berlin manufacturing product in a way most things aren’t.

More on this soon – and you can bet if you follow any RBMA attendees, you’ll see some of their experiments with this hardware show up in social channels!

The last time Tats worked with Red Bull:

There’s a synth symphony for 100 cars coming, based on tuning

And – while it’s important to note he was part of a team – some commentary on the Tats Era at KORG (and still very curious what that team will do next!):

Visionary Tatsuya Takahashi leaves a huge legacy as he departs KORG

Otto ist eine Art OP-1 Minisynth, aber Open Source – für Mitmacher!


Teenage Engineerings OP1 ist ja doch ziemlich erfolgreich. Trotz recht hoher Preise gibt es erstaunlich viele Nutzer dieses possierlichen Apparats mit Recording, Synths und Taschenrechner. Deshalb gibt’s auch Otto, wer ist Otto? Malt der Ottifanten?

Nein, keine Ottifanten, die Älteren erinnern sich, die Jüngeren fragen sich vermutlich: „Was will der Gearnews-Typ eigentlich?“ Otto ist der Name einer Klaviatur mit einem Display in einer Box, etwas größer als der flache, elegante Taschenrechner-Synth – aber das Projekt ist offen und man sucht vor allem Entwickler, denn die Ressourcen findet man bei Github und es gibt schon einen Start mit einigen bereits funktionierenden Modellen.

Der Nutzer Topisani auf Github ist der Kopf und Initiator des Otto Synthesizers. Das Projekt basiert auf einem Raspberry Pi, dem bekannten Bastelrechner. Der Entwickler sollte C++ können und das auf einem sehr neuen Compiler. Aktuell werden also eher Aktive gesucht, jedoch wird das natürlich ein Produkt, das dann aber für alle bereitsteht.

Otto Synthesizer – was ist schon da?

Es gibt einige Screenshots und auch eine Optik, die bereits zu sehen ist. Alles Weitere sollte man mit den anderen besprechen und sicherlich sind auch auf Dauer Fragen sinnvoll, wo und wie man als reiner Unterstützer helfen kann, z. B. mit Geld, Logistik oder so etwas.

Man kann einige Taster für die Steuerung erkennen und eine 2-Oktaven Tastatur. Das Ganze hat einen 320-Pixel-Screen und ist genau so bunt geplant wie die OP1-Idee, nur offener und weiter und mehr. Als Basis wird Jack verwendet, eine bekannte Audioumgebung auf Linux. Aber man ist offen für alles und möchte es so modular wie möglich umsetzen, um das Projekt zukunftsfest zu halten. Wichtig ist nur, dass man dann auch sagen kann „was bist denn du fürn OTTO“?


  • Mehr dazu direkt auf den oben bereits verlinkten Github-Seiten, die übrigens heute von Microsoft betrieben werden.


Hier ein kleines Video, was nicht alles zeigt, sondern nur die Optik und die Idee demonstriert, noch aber nicht, was der Otto Synthesizer wirklich mal können wird.

Meet OTTO – New Raspberry PI Based Multi-Engine Based Synth Inspired by the OP-1

Details via Github:

“Making electronic music is awesome! But for most of us, it requires a lot of setup, a lot of moving a mouse around on a laptop that’s probably not quite equipped to handle realtime audio processing. Don’t you wish you had one single device, which was xbuilt to do it all for you, easily and on the fly?

Introducing the OTTO!

Astro Pi / Tim Peake inspired piece created for the Brighton Modular Meet

Published on Jun 30, 2018 The Mad Music Machine

‘We were thrilled to be invited to run a demonstration of the Mad Music Machine at the Brighton Modular Meet.

We thought it would be a good idea to create a patch using waveforms generated from our Astro Pi data with samples we created from the European Space Agency commentary of Tim Peakes flight from Earth to the International Space Station.
