Weekend Reading: Backups


Public Service Announcement: please do a backup if you haven't in awhile. This weekend we feature articles varying from scary backup stories to how-to safeguard your data with encrypted backup solutions. 


Scary Backup Stories

by Paul Barry

Backups. We all know the importance of making a backup of our most important systems. Unfortunately, some of us also know that realizing the importance of performing backups often is a lesson learned the hard way. Everyone has their scary backup stories. Here are mine.


Reliable, Inexpensive RAID Backup

by Brian C. Lane

As a topic, backups is one of those subject likely to elicit as many answers as people you ask about it. It is as personal a choice as your desktop configuration or your operating system. So in this article I am not even going to attempt to cover all the options. Instead I describe the methods I use for building a reliable, useful backup system. This solution is not the right answer for everyone, but it works well for my situation.


LVM and Removable IDE Drives Backup System

by Mike Fogarty

When the company I work for, a civil engineering and surveying firm, decided to move all its AutoCad drawings onto a central fileserver, we were presented with a backup situation orders of magnitude larger than anything we had confronted before. We had at that time (now considerably larger) about 120,000 files, totaling 200GB, that were in active change and needed to be backed up at least daily.

My first thoughts were of some sort of tape backup system, but as I began to research them, I was shocked at the prices I encountered. A tape autoloader large enough to contain our filesystem ran about $12,000 and a 40Gig tape was $89. When I first convinced my boss to let me run Linux on our servers, cheap was a big selling point. So, what are the alternatives?

In this video, editor Shawn Powers shows us how to do a basic backup in Linux. Or as he puts it, a public service announcement to please do a backup if you haven't in awhile!

8BitMixtapeNEO is a glitchy hackable synth the size of a cassette tape

It’s the size of a cassette tape, has buttons and pots so you can play it as a handheld instrument, it’s open and hackable – and it sounds like 8-bit mayhem.

8BitMixtapeNEO is very, very lo-fi synth built around the Arduino-compatible ATTINY85 chip. But what’s interesting about it is that all that hackable, programmable mayhem is accessible to anyone curious, not just coders.

It sounds mental:

And it’s got some weird and clever features:

Pocket mods: Just like the KORG volca sample, an audio protocol works for upload. So you can send firmware code just by playing a sound file from an audio playback device. Flash with your phone on the fly. (They also suggest a SONY Cassette WALKMAN, of course.)

Lite-Brite: Eight RGB LEDs work as a sort of 8-pixel screen / feedback / Knight Rider display.

Upcycle: Since the PCB is the shape and size of a cassette tape, a re-purposed cassette shape shell works as a case.

Arduino-compatible chip.

Visual programming. There’s a visual, drag-and-drop programming interface you can use as an alternative to uploading code. Have a look:

User mixtapes. They’ve built their own custom community for user-generated tools, including visual effects, sequencers, sounds, and other hacks. It’s here – – and since audio playback upload is easy, you can just flash from any computer or phone or tablet with speakers!

Pricing stars at 65EUR (with that beautiful, artsy PCB). There are various ways to buy, including getting it in person in Berlin – and workshops from Hong Kong to Zagreb to Taoyuan. Check it out:

DPF-Plugins and DISTRHO-Ports update

A new release of DISTRHO-Ports after years without one!
A lot of changes happened on the underlying plugin frameworks (DPF and Juce).
I also updated the way updates are handled, so it will be less work for next time
(and thus, hopefully, have updates more often from now on)

The amount of changes in the plugin frameworks is so big (it has been 4 years since last release!),
that I am not going to write about them in detail.
But the major highlights follow below.

The following new Linux ports were added: (LV2 and VST)
- JuceOPL
- ReFine

The DPF-based plugins had some changes too:
- glBars added
- Kars added
- ndc-Plugs added
- A new DPF-Plugins git repo was created, for easy packaging of all our plugins
- MAX gen~ based plugins can be created, see this link

Since last release, a few projects have appeared that use DPF. Here's a few:
- FTZ Chiptune - Collection of basic waveform synths
- Ninjas - Sample Slicing Plugin
- Wolf-Shaper - Waveshaper with graph editor
- ZamAudio plugin collection
- ZynAddSubFX, uses DPF for its plugin support

Other small changes relevant to the project:
- Nekobi moved to plugins (used to be in ports), as original developer is happy with it
   (and has RW access to our git repo too)
- The DPF "framework" has evolved with JACK Standalone export, Transport sync among other things

Checkout for binary downloads and screenshots.
The complete source code is available at

PS: For those waiting for KXStudio 18.04 ISO release, work is underway, please be patient!

digital audio hacks – Hackaday

1960’s Console Stereo gets Raspberry Pi Touch Screen

When he was but a wee hacker, [WhiskeyDrinker] loved to play with the big console stereo his grandparents had. The idea of a functional piece of furniture always appealed to him, and he decided that when he grew up and had a place of his own he’d get a similar stereo. Fast forward to the present, and a Craigslist ad for a working Penncrest stereo seemed to be a dream come true. Until it wasn’t.

The original physical controls are connected to the Pi’s GPIO

As difficult as it might be to believe, sometimes things we read on the Internet are not true. The “working” Penncrest radio turned out to be a dud. But realizing that the look of the cabinet was more important to him than historical accuracy, [WhiskeyDrinker] decided to outfit it with a Raspberry Pi powered touch screen that would look as close to stock hardware as possible.

The final result really does look like some kind of alternate timeline piece of consumer electronics: where chunky physical buttons and touch screens coexisted in perfect harmony. The vintage stereo aficionados will probably cry foul, but let them. [WhiskeyDrinker] did a fantastic job of blending old and new, being respectful to the original hardware and aesthetic where it made sense, and clearing house where only nostalgia had lease.

A HiFiBerry DAC+ Pro is used to get some decent audio out of the Raspberry Pi, and the touch screen interface is provided by Volumio. [WhiskeyDrinker] mentions that it even has a GPIO plugin which he successfully used to handle getting the physical buttons to play nice with their digital counterparts.

Updating old audio gear is always a sensitive subject around these parts. Sometimes they go so far that the original hardware is almost an afterthought. On the other side of the spectrum are the projects which try to take modern gear and mimic the look of the classics. In any event, one thing is clear: they don’t make ’em like they used to.

Stomping On Microcontrollers: Arduino Mega Guitar Effects Pedal

Effects pedals: for some an object of overwhelming addiction, but for many, an opportunity to hack. Anyone who plays guitar (or buys presents for someone who does) knows of the infinite choice of pedals available. There are so many pedals because nailing the tone you hear in your head is an addictive quest, an itch that must be scratched. Rising to meet this challenge are a generation of programmable pedals that can tweak effects in clever ways.

With this in mind, [ElectroSmash] are back at it with another open source offering: the pedalSHIELD MEGA. Aimed at musicians and hackers who want to learn more about audio, DSP and programming, this is an open-hardware/open-software shield for the Arduino MEGA which transforms it into an effects pedal.

The hardware consists of an analog input stage which amplifies and filters the incoming signal before passing it to the Arduino, as well as an output stage which does the DAC-ing from the Arduino’s PWM outputs, and some more filtering/amplifying. Two 8-bit PWM outputs are used simultaneously to make pseudo 16-bit resolution — a technique you can read more about in their handy forum guide.

The list of effects currently implemented covers all the basics you’d expect, and provides a good starting point for writing custom effects. Perhaps a library for some of the commonly used config/operations would be useful? Naturally, there are some computational constraints when using an Arduino for DSP, though it’s up to you whether this is a frustrating fact, or an opportunity to write some nicely optimised code.

[ElectroSmash] don’t just do pedals either: here’s their open source guitar amp.

vr back

Being artist-in-residency in Ii gave me time to finish an online VR piece for my music project Notstandskomitee, done with WebGL and compatible with modern browsers but preferable to watch on mobile devices like phones and tablets/pads because the device orientation does control the point of view. On IOS devices tab on the world after it loaded to hear the sound. And close the browser tab after you are done so the battery is not drained in the background:

My tradition with VR goes back to the 90s, when VRML was about the next big thing after WWW and HTML, which unfortunately never happened. After experimenting with online VR worlds and the multiuser system Blaxxun, it became appearent that it was to ahead of its time. I concentrated on working with 3d game engines for live visuals for my music projects or art installations, more on the page linked above. Virtual reality will also a part of our installation at Art Ii biennial.
I am happy to see that HTML5 and WebGL take off where VRML left.

open-source – CDM Create Digital Music

There’s a do-everything music box coming from the maker of monome

From the creators of the monome grid, there’s a teaser out now for a new standalone box that could replace the computer for various creative tasks – and that builds on the legendary mlr patch.

The story so far

The monome 40h was arguably the most important first invention in electronic music in the century’s first decade. Its minimalist aesthetics broke from industry norms at the time (and earned accolades in modern art museums, even). It set the tone for music products built on open, community-driven ecosystems. It defined the grid as paradigm for computer music interaction, and in particular a bi-directional relationship that gave feedback with lights. And it set up the value of a controller combined with software to create new interactions with digital sound. Every single one of these things has been endlessly duplicated by makers big and small – it’s actually pretty astonishing just how much Brian Crabtree and partner Kelli Cain were ahead of the curve.

But the thing that really made the original monome 40h work wasn’t that it was an undifferentiated grid. That made a strong visual statement, but Yamaha’s Tenori-On did that, too, and had nowhere near the impact. The monome community took off as music makers, spawning albums, meetups and festivals, and eventually seeing controllers from Novation, Akai, Ableton, and others follow suit, partly because of the software that went with the grid. mlr, build by monome’s Brian Crabtree in Max/MSP, gave the grid musical utility by carving up samples into grids and allowing them to be triggered rhythmically.

tehn with monome prototype from tehn on Vimeo.

At the same time, this meant monome users were tethered to computers. And that destroys the image of the monome as a singular instrument. Brian has had some ideas over the years that could help users get away from that, including the teletype algorithmic module. But the new thing he’s teasing most resembles the previous aleph – a standalone computer stand-in powered by a DSP platform.

If the beginning of the century was about figuring out how to create a computer and controller combination that worked (see Ableton Live, Maschine, et al), maybe now we’ll finally tackle new standalone instruments built on the open-ended possibilities of software.


norns: approaching from tehn on Vimeo.

norns is the new monome box. And like teletype and aleph, it seems to be built around making a dedicated computational device that’s focused on typing as an interface.

Brian has composed some lofty text around what this thing is about, but I’ll … reduce a little.

It looks beautiful – a luxurious block with minimal encoders and display. And the opening teaser “poem” suggests that it can do a variety of tasks related to sound, interfacing, and control (MIDI and CV):

knows something.
adores grids.
cuts sound.
shapes, filters, folds.
keeps rhythm, tells time.
summons waves.
tapes digitally.
speaks lua.
controls voltages.
can MIDI.
radios OSC.
tracks, tabulates, calculates.
sings robot melodies.
shows picture.
makes music.
brings light.
loves birds.
waits patiently.

It’s also nice to see a musical intro, which is how Brian brought out the original grid.

Okay, so it loves birds. But what is it?

It’s a scriptable, connected box with a DSP engine for sound and loads of inputs and outputs for interfacing. Specs:


1/4″. 2 output. 2 input with analog gain stage. all line level. (1)
1/4″ headphone with gain.


128 x 64 OLED, 16-level bright white huge pixels.
3 rotary encoders, standard resolution.
3 keys.
rear status LED indicating power and disk access.


4 x USB ports for devices.
serial tty via USB-mini.


power/charge via USB-mini (high output USB power supply included).
internal lipo battery 2250mAh.


compute module 3 SoC. quad core 1.2ghz, 1gb RAM, 4gb eMMC (faster and more reliable than an sd card).
cs4270 i2s audio codec (low latency).


linux with realtime kernel. (2)

We’ve also got a pic of the PCB:

Now, this is way more like what I’d want than the original, Bluefin DSP-powered aleph. USB allows connections to MIDI, OpenSoundControl(OSC), HID (so various stock USB hardware like mice and joysticks), footswitches, and even CV (over USB, that is). Those technical details got updated today:

It’s the way it’s scripted that gets interesting. Not only is it scriptable with Lua, but the plan appears to be to make an online IDE and community database of scripts, so you can load up a granulator or a delay somebody as built and play with it right away. tehn also promises some interesting features like keypress performance – it’ll be interesting to see how that online scripting works in this golden age of musical livecoding.

Brian also gets into some details of his next take on mlr – an “evolution,’ he calls it – which may be what sells this thing:

virtual tape loops are mapped to grid rows where playback position is displayed and key presses cut to the location.

playback speed (with reverse) is mapped to the grid in addition to record punch in and overdub.

keypresses can be recorded and played back in patterns to automate gestures.

within the cutting interface smaller sub-loops can be selected and looped.

there’s a lot more.

He’s also added more on the first sound capabilities:

norns: cuts from tehn on Vimeo.


in order:

super-parameterized polysynth by @zebra
old-akai-style sampler by @jah
simple percussive polysynth by @tehn
classic outerspace noise by james mccartney
multitrack granulator by @artfwo

norns has two sides: control scripts and sound engines.

the script chooses which sound engine to use. and decides what to do with key and knob input and midi notes and grids. and then considers what to draw on the screen or start a sequencer. and tell the sound engine what to do. (1) or how to sound.

the sound engine tells the script what parameters it has and what kind of analysis data it produces.

it’s a bit like a plugin in a DAW. except here the DAW is the language lua, and the plugin is the entire supercollider environment. (2)

Only 100 aleph units were ever made. It’ll be interesting to see if this makes it further. While it’s easy to knock commodity computers as ugly and inelegant, they’re also what allows access to this kind of music making for most people. Look no further to the livecoding movement, which does this on hardware that can run as cheap as a Raspberry Pi – and which is accordingly spreading all over the world, including in markets where importing gear is expensive.

Then again, that being the case, it remains nice to see something luxurious and beautiful and artful, even if a symbol of what the rest of that can be. We’ve had expansive conversations with Brian since the beginning of his project, so let us know questions for him and we’ll check in.

In the meantime, the monome community are more than a little excited over on the forum.

Oh, and they did find the reference in the name:

“The Norns (Old Norse: norn, plural: nornir) in Norse mythology are female beings who rule the destiny of gods and men. They roughly correspond to other controllers of humans’ destiny, such as the Fates, elsewhere in European mythology.”

Well, then, let the Norns decide how this one plays out. But we’ll be watching.

Want to start learning now?

norns is powered by free software. If you’re thinking you might like to get a norns for yourself – or if you just want to play with sound tools now on your existing computer, for free – I’ve started putting together some resources on SuperCollider and Lua that will help sound DIYers:

Here’s what to learn to get a jump start on the new monome thing

Midichlorians in the blood

VMPK 0.7.0 released

It has been a while! First of all: thank you very much for the million downloads of VMPK! It happened in 2016, but I wasn't paying attention at the time. I didn't post any article around that event, neither released a new VMPK version since that year, so let's cover both things.

Download statistics

Born in 2008, this project is multiplatform from the beginning, with the goal of emulating a MIDI controller device on software; which means: producing (and consuming) MIDI events. The producing part requires another source of human triggered events: computer keyboard, mouse and touch screen events are supported and available on the three main target operating systems. But producing MIDI events without delivering them to a MIDI Synthesizer makes the program useless, with no sound output at all. This has been the experience of most new VMPK Linux users for years. Windows users have a software synth included in the operating system, installed and ready to use, so they may produce sound as soon as they install VMPK from scratch. But Mac and Linux users need to find and install first a suitable synthesizer. Mac OSX also includes a soft synth library, but it is not a ready-to-use service and needs to be activated by a third party software. It's not very hard to find and install, because Apple has always made MIDI users a niche for their products. Good for them.

I've been approached last year by Microsoft people to package and publish VMPK into their Windows Store for Windows 10. Probably the million downloads has something to do with it. I've tried the packaging part without technical problems thanks to the support of the MS Desktop Bridge team, but the store conditions were awful, arbitrary and unfair, so I am not willing to comply with them. This means that VMPK will be available only outside the Windows Store and there won't be an UWP or Windows Phone version either in the future. I don't want to speak about the Apple's App Store. To the hell with them as well.

Linux users have been often made hostages of their distributions and packagers. In theory, the package repositories of each distribution (equivalent to an app store) are made for easy discovery and install of all the software available for Linux, but this is not true in practice. Software integration from different unrelated sources is also the job of the Linux distributions, which they miserably fail as well. I mean that when saying hostages, because the packagers sometimes act as if they want to force their users to follow their own personal preferences, like the gurus of a sect: Jack is the chosen one!!! PulseAudio is evil!!!

More about that later. Let's listen an enlightening Linus Torvalds first:

OK Linus. I've released this time an AppImage package for 64-bit Linux. OTOH, I'm still using Subversion and not planning to migrate the source repository to Git anytime soon.

What I think it would be a good VMPK distribution? Well, first of all, the latest version should be available for install, optionally with some former versions available to choose if the users needs to compare something (like a bug resolved or introduced in the latest version). Second: main functions should be immediately available: the user must be able to simply get sound at once. For Linux, ALSA sequencer inputs and outputs must also be available without any other extra configuration. About network I/O: the Mac OSX and Windows operating systems automatically activate firewalls blocking this function but, as soon as VMPK starts the first time, the OS asks the user for permission to open the firewall for this software. Linux distributions that include an active firewall should listen and learn something here.

The latest VMPK release includes lightweight soft synths for Linux and Mac OSX, which were available as a Drumstick-RT library back-ends for some time. The Linux soft synth is Sonivox EAS, borrowed from Android OSP and ported to Linux + PulseAudio, which was already mentioned in another post.

It is the default output chosen by VMPK upon install, so you need to use PulseAudio if you want to try VMPK. Why the PulseAudio choice? Because it is the default Linux sound server in most distributions: Ubuntu, Fedora (Red Hat), OpenSUSE, etc. I know that there has been a lot of criticism among the Linux audio community about PA, but honestly: I can't care less about arguments that sound like fanaticism. Someone told me that: “many people in linux-audio avoid PA like the plague.” Well, I'm sure you know that many computer users avoid Linux like a plague, but I don't let a handful of haters to influence my decision of keeping VMPK available for Linux users. And at the end of the day, this is my personal project and I am who decide the road-map. This is also free software. If you don't like something or have good ideas to get it better, you may contribute with code or make your own fork.

Audio – Stefan Westerfeld's blog

SpectMorph 0.4.0 released

A new version of SpectMorph, my audio morphing software is now available on

One main feature is that besides providing VST, LV2, JACK and BEAST support on Linux, this version is the first version that also provides a VST plugin for (64-bit) Windows.

To make the VST plugin portable to Windows, the plugin UI now uses the pugl library (with GL + Cairo) instead of Qt5. This should also allow supporting macOS in the future.

Since the whole plugin UI was reimplemented, a new design is used, and many small improvements were made; the UI is also ready for high(er) DPI displays, everything can be scaled using a global zoom factor. Below is a screenshot of the new UI:

Other changes are:

  • A new non-linear mapping from midi velocities to volumes was implemented
  • New instrument: French Horn
  • Improved tools for building custom instruments
  • LPC/LSF support removed

KXStudio News

Cadence 0.9.0 release and KXStudio 18.04 preparations

Cadence 0.9.0 has just been tagged in its git repository.
No new features have been added to the code-base.
The release is focused on the Qt5 port, and of course the fixes that have been added over time.
Qt4 is no longer supported; the code was updated to work with Qt5, without having a fallback Qt4 mode (unlike Carla).
Cadence Qt5 port is needed for a proper KXStudio 18.04 release, as we will be using KDE5 Plasma as desktop environment.

The KXStudio "Welcome" wizard has also been ported to Qt5.
This finalizes the Qt4 => Qt5 porting process, with all KXStudio tools now running in Qt5.

In other news, the preparations for KXStudio's 18.04 ISO release have started.
The decision is to use Neon as the base distro for the next ISO images, with Breezy-Dark as default theme.
The KXStudio configuration files have been ported from KDE4 to KDE5, with only a few tweaks missing now.
If you're running the KXStudio repositories with Neon 16.04, you can already install the kxstudio-desktop-neon package. :)

Note that Ubuntu 18.04 (and thus Neon 18.04) is not out yet, so a release will of course have to wait for them first.
(Neon does not actually have their 18.04 repositories fully ready at this point)
We will have beta images first, to let users test and give feedback.
When everything seems to run fine, and I am happy with the results, the final image will released.
No estimation on the 'when' just yet though - it will be out when it's ready - so please don't keep asking. ;)

Qtractor 0.9.0 - An Early Spring'18 Release


Qtractor 0.9.0 (early spring'18 beta) is now released!

The change-log for this spring-time release goes as follows:

  • New View/Options.../Plugins/Experimental/Show plugins on track list/left pane option is in effect on tracks that are tall enough in height for their plugins list to fit on the Bus column.
  • Fixed a day-zero bug over the MIDI Insert (Send/Return) pseudo-plugin, which was duplicating MIDI events onto the next LV2 plugin in chain, causing strange hanging notes, mutes, retriggerings and what not.
  • MIDI track and clip note min/max range display now fixed.
  • MIDI Program Change events (PC) now have their proper program number as parameter, instead of value, on the internal MIDI event representation.
  • Merging MIDI clips while on SMF Format 0 has been fixed: was merging always onto the same MIDI channel (2), most often the wrong one, resulting in an empty or blank clip.
  • When importing from standard MIDI files (SMF), set track names from Mtrk TRACKNAME meta-events instead of filename.
  • Avoid asking to save as to existing or just newly created clip file-names, whenever possible.
  • Disable singleton/unique application instance setup logic when the display server platform is not X11.
  • Whether to use native file browser/requester dialogs is now an effective option when launching under NSM session management (was once disabled initially).
  • Content files are now saved as symlinks when saving to JACK and/or NSM session directories/folders.
  • Trying to get CC14 MSB+LSB (course+fine) running status on, no matter whether each pairing event are under 200ms apart.
  • Possible VST plug-in GUI reparenting hack/fix on Qt5/Xcb.


Qtractor is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework. Target platform is Linux, where the Jack Audio Connection Kit (JACK) for audio and the Advanced Linux Sound Architecture (ALSA) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.
