Starless, a community-built OS for the MOD Dwarf.

In 2024 we opened the MOD OS images, so anyone could change the software and share the result. One Dwarf owner did exactly that. Seventeen releases later, Starless has its own community, and it changed how we develop MOD OS. Here is his story, in his own words, and what it led to.

Andrea Del Signore, creator of Starless

Why I started Starless

By Andrea Del Signore

I first heard about MOD in its early days through the open source world, which I’ve always been passionate about. Then I lost track of it, until I came across an ad for a used Dwarf and bought it.

At the time my main unit was a Line 6 Helix LT, and I immediately saw the Dwarf’s potential: a compact device with creative routing options, a perfect fit for my acoustic and classical guitar rig. But a few software limitations made me doubt it could work live for me. They were small details, but vital ones. I couldn’t change a pedalboard’s parameters on the fly without a computer, not even to turn down a reverb or adjust an EQ. The plugins and the creative possibilities were there, but those few gaps kept me dragging the big, heavy Helix to every gig.

I noticed that almost all the sources were available on GitHub and that, in theory, I could modify the software and patch the official images.

Andrea Del Signore

Then I noticed that almost all the sources were available on GitHub and that, in theory, I could modify the software and patch the official images. I spent the next three or four evenings on the couch reading code and setting my first goals. The plan was simple. First, a minimal change to get familiar with the codebase. Then, the few features I needed to play live without worrying, so I could finally replace the Helix.

After a few weeks of trial and error I built my first image. It introduced port groups in the UI and two complementary ways to edit pedalboard parameters: new firmware and a new mobile-friendly page, now known as the Performance View.

From there, the community stepped in. Abotte, Rom, Fer and others adopted the image, tested it and gave me feedback, and that is how Starless was born. The name comes from what I was working on at the time: a classical guitar arrangement of King Crimson’s song of the same name.

A few months later I sold my Helix and kept adding features that help both while editing and during performances. Today other talented developers, such as Stefan and Andy, are helping me refine Starless for use cases beyond my own.

I want to thank Abotte, Toferyu, Remy, Rom, Fer, Zwabo, UnvisualStudio and many others, along with the MOD team for the help in the very first days. And finally, Gianfranco and MOD Audio, for so warmly welcoming the development of this project.


What Starless is today

Starless is an alternative OS for the MOD Dwarf, made possible by the open images we published with MOD OS 1.13.5 in October 2024. It is now on version 17, and its latest release added, among other things:

  • Complete pedalboard editing from the Dwarf itself, no computer needed
  • Tone3000 support in the NAM, cabinet and IR loaders
  • Stereo cables and cable teleporting, for tidier pedalboards
  • A per-plugin CPU monitor, mouse-wheel zoom and a canvas that resizes itself as you add plugins

AndyCap has also been working on mapping the same control to the Dwarf’s own controls, MIDI, CC and CV at the same time, now in beta. See it in action on the forum.

Try Starless

Starless is Andrea’s project, with its own name, schedule and decisions. It is an unofficial image, so MOD does not provide support for it. The community does, on the forum.

  1. Back up first. Use the Backup & Restore function in the web interface (see the MOD wiki).
  2. Install the latest Starless image as a manual upgrade. Your pedalboards and downloaded plugins stay where they are.
  3. Ask on the forum if anything is unclear. Here is one Dwarf owner’s first install, step by step.

What Starless changed: the new MOD OS release flow

Starless showed us something important. When the software is open, the people who use it every day will improve it, and their work deserves a real way into the product. So we changed how official MOD OS releases are made.

MOD OS is now released through three channels, a model inspired by how long-running open source projects like Debian work:

STABLE

Official production releases, after testing. What most users run.

TESTING

Official release candidates, built from MOD’s work and community contributions, and offered in the web interface. A new one every two to four weeks.

COMMUNITY

Independent images, built and distributed by their authors. Starless is the first.

The first release candidate under this flow is MOD OS 1.14, and it is already built from community work. It brings Tone3000 into the web interface, so you can browse and load captures directly on your device, and a “Report an Issue” button, so testing is one click away. The announcement of the new flow publicly thanked five community contributors: Andrea Del Signore, Andy Cap, Remy D, Stefan D and Mark Melvin.

In other words: what happened with Starless is now how MOD OS moves forward. Community work flows in, gets tested in the open, and ships.


Join in

All of this happens on the forum, through people testing, reporting problems and asking for features. Try a release candidate and tell us what breaks. Try Starless and tell Andrea what you would like next. And if you have your own idea for MOD, the forum is where it starts.

News – Ubuntu Studio

Ubuntu Studio 26.10 Beta Released

Graphic showing the logo and name of Ubuntu Studio 26.10 Beta, titled 'Stonking Stingray' against a dark background.

The Ubuntu Studio team is pleased to announce the beta release of Ubuntu Studio 26.10, codenamed “Stonking Stingray”.

While this beta is reasonably free of any showstopper installer bugs, you will find some bugs within. This image is mostly representative of what you will find when Ubuntu Studio 26.10 is released on October 15, 2026.

Ubuntu Studio 26.10 is a standard release and will be supported for 9 months, until July 2027. We encourage everyone to try this image and report bugs to improve our final release.

Special Notes

The Ubuntu Studio 26.10 disk image (ISO) exceeds 4 GB and cannot be downloaded to some file systems such as FAT32 and may not be readable when burned to a DVD. For this reason, we recommend downloading to a compatible file system. When creating a boot medium, we recommend creating a bootable USB stick with the ISO image or burning to a Dual-Layer DVD.

Images can be obtained from this link: https://cdimage.ubuntu.com/ubuntustudio/releases/26.10/beta/

Full updated information, including upgrade instructions, is available in the Release Notes.

Only Install What You Need

A common piece of feedback we hear is that people prefer to start with a lean base and install only the tools they actually use, rather than getting an overwhelming number of pre-installed packages. We hear you.

Ubuntu Studio includes a minimal install option in the installer. This gives you the Ubuntu Studio desktop experience — the theme, the audio configuration, the optimized settings — without the full suite of creative applications. From there, you can use Ubuntu Studio Installer to add exactly the workflows you want: audio, graphics, video, photography, or publishing: à la carte.

Alternatively, if you’re already running Kubuntu, Ubuntu, Lubuntu, Xubuntu, or any other official Ubuntu flavor, you don’t have to reinstall at all. Just install the Ubuntu Studio Installer package and pick the components you need. This has always been an option, but we want to make sure everyone knows about it.

The full install remains available for those who want a complete creative workstation out of the box, and that’s a perfectly valid choice too.

New and Improved This Release

Ubuntu Studio 26.10 builds on the 26.04 LTS release with improvements to Ubuntu Studio Installer, Ubuntu Studio Audio Configuration, and included creative tools.

  • Ubuntu Studio Installer package selection: You can now expand a metapackage’s Depends and Recommends and select individual packages.

  • Ubuntu Studio Audio Configuration: The app now uses a single-window, tabbed control-panel layout, with PipeWire quantum settings organized on the Audio tab.

  • PipeWire settings: The installer offers the PipeWire settings app appropriate to the detected desktop environment.

  • Newly-included Audio Applications: Sonic Pi, SuperCollider, JNoise, and the SuperCollider 3 plugin suite are available through Ubuntu Studio’s audio package selections.

Major Package Upgrades

  • OBS Studio 32.2.2
  • FreeShow 1.6.5 (snap)
  • QPrompt 2.0.2
  • RaySession 0.18.0
  • Patchance 1.4.0
  • DistroAV 6.2.1 for NDI support in OBS Studio
  • Kdenlive 26.08.1
  • Krita 6.0.3
  • GIMP 3.2.6
  • Ardour 9.8.0
  • Scribus 1.6.6
  • Audacity 3.7.8

There are many other improvements, too numerous to list here. We encourage you to look around the freely-downloadable ISO image.

Known Issues

How You Can Help

Please test using the test cases on https://tests.ubuntu.com. All you need is a Launchpad account to get started, and to join the Ubuntu QA Team.

Additionally, we need financial contributions. Our project lead, Erich Eickmeyer, is working long hours on this project and trying to generate a part-time income. Go here to see how you can contribute financially (options are also in the sidebar).

Frequently Asked Questions

Q: Does Ubuntu Studio contain snaps? A: Yes. Mozilla’s distribution agreement with Canonical changed, and Ubuntu was forced to no longer distribute Firefox in a native .deb package. We have found that, after numerous improvements, Firefox now performs just as well as the native .deb package did.

Thunderbird is also a snap in order for the maintainers to get security patches delivered faster. This is done by the Thunderbird team in cooperation with Canonical.

Additionally, FreeShow is an Electron-based application. Electron-based applications cannot be packaged in the Ubuntu repositories in that they cannot be packaged in a traditional Debian source package. While such apps do have a build system to create a .deb binary package, it circumvents the source package build system in Launchpad, which is required when packaging for Ubuntu. However, Electron apps also have a facility for creating snaps, which can be uploaded and included. Therefore, for FreeShow to be included in Ubuntu Studio, it had to be packaged as a snap.

Also, to keep theming consistent, all included themes are snapped in addition to the included .deb versions so that snaps stay consistent with our themes.

We are working with Canonical to make sure that the quality of snaps goes up with each release, so we please ask that you give snaps a chance instead of writing them off completely.

Q: If I install this Beta release, will I have to reinstall when the final release comes out? A: No. If you keep it updated, your installation will automatically become the final release.

Q: Will you make an ISO with {my favorite desktop environment}? A: To do so would require creating an entirely new flavor of Ubuntu, which would require going through the Official Ubuntu Flavor application process. Since we’re completely volunteer-run, we don’t have the time or resources to do this. Instead, we recommend you download the official flavor for the desktop environment of your choice and use Ubuntu Studio Installer to get Ubuntu Studio — which does not convert that flavor to Ubuntu Studio but adds its benefits.

Q: What if I don’t want all these packages installed on my machine? A: See the “Only Install What You Need” section above. Use the minimal install option and then add only the metapackages, configurations, or individual packages you want with Ubuntu Studio Installer.

Mortal FM Kombat: Plogue’s meticulous OPMZ Yamaha emulation totally slaps

We're awash with emulations at the moment, but this one is on another level. The chip that powered everything from Yamaha’s little-known CX5M computer to the best 80s FM synths and video game masterpieces gets a long-awaited (unofficial) rendition on your computer, and it's just about perfect -- both as a instrument plug-in and an ultra-authentic player for classic games. And where this emulation started was physical, not virtual: a workbench, vintage gear and documentation, research, and physical labor.

digital audio hacks – Hackaday

Making a Digital Music Player for Cassette Decks

In the cross-over between the era of tapes into that of MP3s, you’d see quite a few of those special cassette tapes that were actually digital music players inside. Some simply provided a 3.5 mm input, while others were complete MP3 players or Bluetooth receivers that just happened to also output to the magnetic read head of a cassette player. Recently [Jonathan Rowny] decided to make his own version of the latter.

Although getting the actual audio signal into the read head is easy enough – requiring little more than its equivalent being used as a write head on the cassette side – actually interfacing with the player’s mechanisms like auto-stop, reverse and so on requires the use of some gearing that detect motion on what would be the tape spools, as well as transfer the motion from the take-up spool to the other spool so that features like the auto-stop mechanism don’t get triggered.

A lot of inspiration here can be found in e.g. the videos made by [Clint] of [Lazy Game Reviews] who looked at a number of examples – including their internals – over the years, with various levels of functionality. For this particular implementation an ESP32-S3 module is used for the brains, along with a microSD card reader for music and a PCM5102 I2S audio codec to create the analog audio signal.

The gears were printed using an SLA printer and seem to work all right. Unfortunately he didn’t realize the importance of the capstan as the mechanism that actually transports the tape, so its motion was not measured as is done in the better cassette adapters. This will likely be corrected in a future iteration, however.

“Bullet-Proof” KDE Initiative: How Ubuntu Studio Benefits

As should be obvious from browsing our website for any amount of time, Ubuntu Studio releases a Long-Term Support (LTS) release every two years. The latest LTS release happens to be our latest release: 26.04. What’s more is we just released 26.04.1, a roll-up of bugfixes and security updates, on August 27th.

Also announced is the “Butllet-Proof” KDE Initiative, where Kubuntu Focus, Techpaladin Software, and KDE e.V. are working together to make Plasma 6.6, along with KDE Frameworks, an LTS release as well. This means that Techpaladin, Kubuntu, and Kubuntu Focus will be working to fix bugs in the version of the desktop environment and back-end libraries released in Ubuntu Studio 26.04 LTS. This means that, while Kubuntu will be primarily working on the Stable Release Updates as provided by KDE, Ubuntu Studio uses the same packages that get these updates.

Our project leader, Erich Eickmeyer, has been doing what he can to help support Kubuntu with this task from his side, while the Ubuntu Studio team (including Erich) focuses on bug fixes to the multimedia applications included with their own Stable Release Updates for the life of 26.04, which is three years total until April 2029.

That, combined with Ubuntu Pro (free for every user up to 5 simultaneous machines) means you will not only receive bugfixes better than in the past, which was done at best effort, but also benefit from the security updates provided by Canonical. Yes, even Ubuntu Studio can use Ubuntu Pro. Do note that Ubuntu Pro will not extend the support time period for Ubuntu Studio, but give the added benefit of sponsored security updates.

If you would like to help with everything Ubuntu Studio has going on, from supporting the LTS to supporting the upcoming 26.10 release due in October, please feel free to join us!

Additionally, while there was an initial jump in monetary support following the 26.04 LTS release, it has dropped-off considerably. Please consider becoming a monthly monetary contributor to help support this project. Remember, our website now has a monthly cost along with the usual cost of packaging and development. If you cannot commit to a monthly monetary contribution, please consider at least a one-time contribution, even if you’ve given before. Even if it’s just a tank of petrol! For those already giving, thank you so much for your continued support. It means the world to us, and allows us to continue giving you and others this operating system for free! You’ve helped countless people throughout the world!

digital audio hacks – Hackaday

DOOM Played on Series of 555 Timers

It’s technically true that any piece of software can be reproduced in hardware, although modern software’s size and complexity generally makes this a non-starter. But if we go far enough back in time, older software becomes easier and easier to implement in hardware. The original DOOM from 1993 might one day be recreated in full this way, but that day is not today. Instead, [Nick] has recreated the original music from that game, playing the opening track in nothing but 555 timers.

The circuit starts with a 555 timer that acts as a system clock with a rate of just over 7 Hz. These pulses feed a binary counter which in turn feeds a decoder, giving the circuit 15 positions. Each output of the decoder feeds to a diode matrix which stores information about what pitch the circuit should play. The circuit only needs to play six pitches so the diodes effectively connect each moment in time to one of these six notes. From there the circuit feeds into a set of switches which select different resistor networks of another 555 which is actually responsible for producing sound. The resistor networks have different values to adjust the timing of the 555 to produce different pitches.

Of course this entire exercise is largely academic as almost any microcontroller would be able to be programmed to play this chiptune quite easily, but it’s not a bad idea to get down into the weeds of digital logic from time to time in order to refine one’s skills and knowledge about what’s really going on in the inner workings of circuits. Or, go even deeper than that and build the logic gates themselves from first principles.

Ardour3 + VideoTimeline -- Live System

Work in progress.. feel free to edit this wiki-page if you can improve it.

About

a3vtl.img is a live-system to evaluate the Ardour3 video-timeline. Live-system - you run it from a USB flash drive. It won't touch your hard-disk and does not require installation. It comes with a whole bunch of audio-software and can be used as studio to go, but you're better off to rely on a dedicated distribution for the latter (e.g. AVLinux, kxStudio, Ubuntu-Studio,…).

Prerequisites

  • x86 compatible PC
  • ≥ 1GB RAM
  • USB-flash-drive ≥ 2GB

Installation

You need to write the disk-image to a raw-device (USB-stick, CF-CARD,..) that your computer can boot from.

Doing that destroys all data that is on the USB-drive!

  1. Download the disk-image http://rg42.org/d/a3vtl_20120805-1.img mirrored at linuxaudio.org (preferably download from the linuxaudio.org mirror - it offers better bandwidth and more simultaneous downloads).
  2. and write it to a USB-drive – _not_ save it as file _on_ the USB-stick, but write it as disk-image
  3. boot from the USB-device

Regarding (2.):

on GNU/Linux this can be accomplished by various ways. The easiest is probably to use usb-creator (usb-creator-gtk on Ubuntu or Arch-Linux).

The canonical way is to use dd on the commandline e.g. if your USB-device is /dev/sdb

dd if=/path/to/downloads/a3vtl_VERSION.img of=/dev/sdb

This also works on OSX, disk-devices are called /dev/disk1, /dev/disk2, etc instead of /dev/sdb, /dev/sdc,.. although you may prefer to use the Disk Utility GUI.

On windows: http://www.pendrivelinux.com/ is the probably the easiest way to write a disk-image onto a USB-key.

Persistence

The disk-image is a read-only live-system. Every time you boot you will have a pristine system. None of your modifications are saved.

In order to retain customizations, you can create a partition with the label 'live-rw' which will automatically be overlaid. The 'live-rw' partition can be on any medium, although it is convenient to keep it on the same disk as the OS. Say, if your USB-drive is 8 GB, you can use the remaining space of 6.5 GB (the live-system is ~1.5 GB) for storage and customizations.

Note: the live-rw partition only saves modifications done to the pristine system. It uses a rather smart technique called AUFS to do so. It is not a data-partition per se and can only be used with a live-system of the same version. If you plan to do serious A/V work, store it on an external hard-disk.

Getting Started

Ardour3 is not [yet] documented. There are bits and pieces of floating around. If in doubt, ask for help via IRC chat.

In the $HOME folder, resides an example video for testing <tt>timecode25-test.mov</tt>, that can be loaded as video into Ardour3: Launch Ardour3, create a new session and choose <em>File &rightarrow; Open Video</em> from Ardour's menu…

The video-timeline should be pretty much self-explanatory:

  • Menu→Session→Open Video
  • Menu→Session→Export→Video
  • Menu→View→Rulers→Video (or right-click the ruler/marker bar → Video)
  • Menu→View→Video Monitor (xjadeo)
  • Menu→Edit→Preferences→Video
  • Menu→Session→Video maintenance→ … (manual video server interaction)

Advanced -- Shell script to create USB drive

#!/bin/bash
# the disk-device to use: 
DEVICE=/dev/sdb # or /dev/mmcblk0 or /dev/hdb ,...

URL=http://robin.linuxaudio.org/a3vtl_latest.img
URL=http://rg42.org/d/a3vtl_latest.img

# Download the image and write it to the disk:
curl http://rg42.org/d/a3vtl_latest.img | dd of=$DEVICE bs=64k

### OPTIONAL: ###  
# re-read the partition-table after the image has been written
partprobe $DEVICE
# create a 2nd partition using the rest of the space on the device..
echo -e "n\np\n2\n\n\np\nw\n" | fdisk $DEVICE
# ..and create an ext4 filesystem on it, labeled live-rw'
