Carla 2.0 beta7 is here!

Hello again everyone, I am glad to bring you the 7th beta of the upcoming Carla 2.0 release.
Last time I said beta6 would be the last beta, but let's ignore that for now... ;)

This release focuses on bug-fixes rather than new features.
Most of the new features were added because of contributions, which are very appreciated.
There are no big flashy screenshots this time, sorry.

One breaking change for this release is the removal of most of the plugins bundled in Carla's code.
They were moved into a separate repository, to keep Carla's code-base smaller.
If you are building Carla yourself and you want those extra internal plugins, make sure to enable git submodules.

Here is a list of the most relevant changes and fixes for this release:

  • Add confirmation dialog for quitting Carla
  • Add confirmation dialog for "Remove All" and "New File" actions
  • Add internal MIDI Channel A/B plugin
  • Add semitones parameter to internal midi-transpose plugin
  • Implement move up/down plugins in rack (right-click menu)
  • Implement LV2 UI port notifications to feedback messages to UI
  • Implement more libjack stubs, Catia now loads inside Carla :)
  • Transport controls are now considered stable and always enabled, no longer in experimental settings
  • Disable ableton-link and audio kits search UI elements if not built/enabled
  • Do not capture logs if running in nogui mode
  • Do not use or check for kVstParameterUsesIntegerMinMax VST property
  • Do not lockup on close in case audio driver stops working
  • Export LV2 window is now a simple combo-box, making it more usable
  • Save plugin author name in exported LV2 plugin
  • Increase polling rate for non-gui mode (30 Hz), fixes slow OSC handling
  • Fix mouse position offset of Carla-embed mouse events
  • Fix processing of internal plugins with multi MIDI inputs
  • Fix crash when closing a session containing bridges with Ctrl+C
  • Fix patchbay/graph to work with variable buffer sizes
  • Fix some issues regarding integer parameter control
  • Fix controlling logarithmic parameters with MIDI CC
  • Fix "MIDI CC 0x01" not selectable in some systems
  • Fix loading of VST plugin parameters and LV2 state for plugin bridges
  • Fix carla-single usage under ladish
  • Fix file dialog filter of the internal MIDI file plugin

Downloads

To download Carla binaries or source code, jump on over to the KXStudio downloads section.
If you're using the KXStudio repositories, you can simply install "carla-git" (plus "carla-lv2" and "carla-vst" if you're so inclined).
Bug reports and feature requests are welcome! Jump on over to the Carla's Github project page for those.

Future

The next Carla release is meant to close the 2.0 features, and focus on feature parity between all OSes.
It might take some time though (unless there is major regression that makes a new release required).

For now I plan to focus on other things that have been on the backlog for some time, including DPF, KXStudio 18.04 ISO and JACK maintenance.
News on that will be published when something is ready, please be patient.

open-source – CDM Create Digital Music

Get your Marbles: VCV adds free Mutable Instruments module

Out of a huge landscape of modules, Mutable Instruments stands alone with some of the best options. And those Mutable tools continue to make their appearance, for free, in VCV rack in software.

As we reported previously, VCV Rack are porting the open source, digital module line from hardware to software form once they’ve been shipping for a while.

The latest is another special addition: Marbles is a random voltage generator, reborn in the onscreen Rack software as Random Sampler. (That term also describes me, at a buffet.)

Random what?

Well, basically, Marbles is both a source of randomness and a sampler that can reproduce patterns. On the randomness side, you can generate clock or control signals – or modify external inputs – and add variation, from subtle to chaotic, slight fuzziness to branching patterns. That keeps things from getting too repetitive.

And then, in case you actually want some repetition or a recognizable phrase, you also have a sampler that stores and recalls patterns of voltages, cleverly dubbed “deja vu.”

That’s to me is a beautiful model of how you might want to control chance and variation, giving ears new and recognizable sounds, compositionally. Of course, this being a Mutable module, that power is consolidated in a few knobs, which can also be a delight to play with.

To try these in VCV’s Rack application, first install Rack, then look to the Audible Instruments preview plug-in:

https://vcvrack.com/AudibleInstruments.html#preview

And a lot of us are now installing multiple modulars on our computers and choosing to use a particular one when the use arises. So if the constantly-under-construction, wild and woolly developer side of VCV Rack makes you long for a more stable solution, it’s worth mentioning that Softube’s excellent Modular and all the paid add-ons are now steeply discounted. That includes an implementation of Mutable’s superb Clouds:

https://www.softube.com/index.php?id=mi_clouds

Kudos to Mutable and creator Olivier Gillet. He’s proven that software can be open source but sustainable commercially, and that it can be successful across multiple platforms at once – hardware and software. For anyone bold enough to follow, that could be a compelling direction for musical tools to take.

And after all, no one can resist marbles…

digital audio hacks – Hackaday

Transforming A Bookshelf Speaker Into A Portable Boombox

There’s a lot of fun to be had in modernizing an old boombox but what about turning one of those ubiquitous shelf speakers into a portable boombox, complete with a handle for carrying? That’s what [GreatScott] did when a friend gave him a just such a shelf speaker.

These days you’d very likely use your phone as the audio source so he included a 20 watt stereo class D amplifier which could be disconnected at the throw of a switch if not needed. To power the amplifier he used 16 18650 lithium-ion batteries which were leftover from previous projects. He estimates they should give him around 100 hours of enjoyable tunes. And to make further use of the batteries, he also added a USB charger so that he could charge up his phone from it, something else which is nice to be able to do when on the road.

A battery management system (BMS), an XT60 connector for charging the batteries, his battery level indicator circuit which we talked about before, a new passive audio crossover, and some rather nice work on that case all round out the boombox. Check out his full construction in the video below and make sure to stay until the end when he gives a taste of its awesome sound (you may even swear your desk is vibrating from the bass despite wearing earbuds, like we did).

And on the subject of speaker-to-boombox conversions, here’s one from a few years ago which makes use of a car MP3 player module giving it FM, USB, and SD card support.

digital audio hacks – Hackaday

Freak Out Your Smartphone with Ultrasound

There’s a school of thought that says complexity has an inversely proportional relation to reliability. In other words, the smarter you try to make something, the more likely it is to end up failing for a dumb reason. As a totally random example: you’re trying to write up a post for a popular hacking blog, all the while yelling repeatedly for your Echo Dot to turn on the fan sitting three feet away from you. It’s plugged into a WeMo Smart Plug, so you can’t even reach over and turn it on manually. You just keep repeating the same thing over and over in the sweltering July heat, hoping your virtual assistant eventually gets the hint. You know, something like that. That exact scenario definitely has never happened to anyone in the employ of this website.

Black Hat 2017 Presentation

So it should come as no surprise that the more sensors we pack into devices, the more potential avenues of failure we open up. [Julio Della Flora] writes in to tell us of some interesting experiments he’s been performing with the MEMS gyroscope in his Xiaomi MI5S Plus smartphone. He’s found that with a function generator and a standard speaker, he’s able to induce false sensor readings.

Now it should be said, [Julio] is not claiming to be the first person to discover that ultrasonic sound can confuse MEMS gyroscopes and accelerometers. At Black Hat 2017, a talk was given in which a “Sonic Gun” was used to do things like knock over self-balancing robots using the same principle. The researchers were also able to confuse a DJI Phantom drone, showing that the technique has the potential to be weaponized in the real-world.

It’s interesting to see more validation that not only is this a continuing issue with consumer devices, but that it doesn’t necessarily take expensive or exotic hardware to execute. Yet another reason to take ultrasound seriously as a potential threat.

Bitwig Studio 2.4: crazy powerful sampler, easier control

The folks at Bitwig have been picking up speed. And version 2.4, beta testing now, brings some promising sampler and controller features.

The big deal here is that Bitwig is going with a full-functioning sampler. And as Ableton Live and Native Instruments’ Maschine pursue somewhat complex and fragmented approaches, maybe Bitwig will step in and deliver a sampler that just does all the stuff you expect in one place. (I’m ready to put these different devices head to head. I like to switch workflows to keep fresh, anyway, so no complaints. Bitwig just wins by default on Linux since Ableton and NI don’t show up for the competition. Ahem.)

Meet the new Sampler: manipulate pitch, time, and the two in combination, either together in a traditional fashion or independently as a digital wavetable or granular instrument. Those modes on their own aren’t new, but this is a nice way of combining everything into a single interface.

Sampler

The re-built Sampler introduces a powerful wavetable/granular instrument. At its heart are multiple modes that combine effectively different instruments and ways of working with sound into a single interface:

“Repitch” / Speed + pitch together: The traditional sampler mode, with negative speeds, too (allowing it to behave the way a record player / record-scratch / tape transport does).

“Cycles” / Speed only: Speed changes, pitches stay the same. There’s also a Formant control, and the ability to switch on and off keyboard tracking. (In other words, you can scale from realistic-sounding speed changes to extreme metallic variations.)

“Textures” / Granular resampling / independent pitch and speed: Granular resynthesis divides up the sound into tiny bits allowing independent pitch and time manipulation (in combination), and textural effects. Independent speed, grain size, and grain motion (randomization) are all available as parameters.

Freeze: Each mode lets you directly manipulate the sample playhead live, using a controller or the Bitwig modulators. That emulates the position of a needle on a record or playhead on a tape, or the position in a granular playback device, depending on mode – and this is in every single mode.

Oh. Okay. Yeah, so those last two are to me the way Ableton Live should have worked from the beginning – and the way a lot of Max, Reaktor, Pd, and SuperCollider patches/code might work – but it’s fantastic to see them in a DAW. This opens up a lot of live performance and production options. If they’ve nailed it, it could be a reason to switch to Bitwig.

But there’s more:

Updated Multisampler Editor: Bitwig’s Sampler already had multisampler capabilities – letting you combine different samples into a single patch, as you might do for a complex instrument, for instance. Now, you can make groups, choose more easily what you see when editing (revealing samples as you play, for instance), and set modulation per zone. There’s also ping-pong looping and automatic zero-crossing edits (so you can slice up sounds without getting pops and clicks).

Multi-sample mode lets you work with zones in new ways, for more complex sampling patches.

Sequence modulation

There’s a new device that lets you step sequence modulation. Here’s how they describe that:

ParSeq-8 is a step sequencer for modulation.

ParSeq-8 is a unique parameter modulation sequencer, where each step is its own modulation source. It can use the project’s clock, advance on note input, or just run freely in either direction. As it advances, each step’s targets are modulated and then reset. It’s a great way to make projects more dynamic, whether in the studio or on the stage. (Along the way, our Steps modulator got some improvements such as ping-pong looping so check it out too.)

Also in the modulation category, there’s a Note Counter — count up each incoming note and create cycles of modulation as a result.

Note Counter.

Note FX Layer.

More powerful with controllers

Bitwig has been moving forward in making it easy to map hardware controls to software, even as rival tools (cough, Ableton) haven’t advanced since early versions. That’s useful if you have a particular custom hardware controller you want to use to manipulate the instruments, effects, and mixing onscreen.

Now there’s a new visualization to give you clear onscreen feedback of what you’re doing, making that hardware/software connection much easier to see.

Visualize controllers as you use them – so the knob you turn on your hardware makes something visible onscreen.

There’s also MIDI channel support. MIDI has had channels since the protocol was unveiled in the 80s – a way of dividing up multiple streams of information. Now you can put them to use: incoming MIDI can be mapped and filtered by channel. That’s … not exciting, okay, but there are dedicated devices for making those channels useful in chains and so on. And that is fairly exciting.

MIDI channel support – essential for working with MIDI, but implemented here in a way that’s powerful for manipulating streams of control and information.

And more stuff

Also in this release:

Bit-8 audio degrader gets new quantization and parameters for glitching or lightly distorting sound
Note FX layer creates parallel note effects
There’s more feedback in the footer of the screen when you hover over parameters/values
Resize track widths, scene widths
Color-code scenes

Looks like a great upgrade. Beta testing starts soon, to be followed by a release as a free upgrade for Upgrade Plan users this summer.

07: Post LAC Developing Frenzy

Hey All!

As you know last week there was the LAC ’18 held at C-Base, Berlin. It was again an awesome event (huge thanks to the organizers!) OpenAV done a quick lightning talk about Ctlra, checkout the video below (clicky the image to play the OpenAV section of the lightning talk session : ) There were some questions after the talk – even some questions for members of the audience!

We discussed many aspects of the Ctlra library with other Linux Audio Developers – and we’re now in the “solution space” of mapping the hardware control surfaces to the many DAWs and audio-software projects that exist. In short; there’s a huge amount of development done in the last few days to enable complex multi-layered mappings with minimal host complexity! A showcase PR is available here for casual viewing… the ~1000 LOC that was added to prototype this..

If you have input on the mapping strategy, or want to discuss mapping and hardware control surfaces, please do get in touch – now is the right time!

Cheers and chat soon with more updates on Ctlra and Mappa, -Harry of OpenAV

MRuby-Zest: a Scriptable Audio GUI Framework

Screenshot of framework in action

zyn fusion osc

Abstract/Intro from paper

Audio tools face a set of uncommon user interface design and implementation challenges. These constraints make high quality interfaces within the open source realm particular difficult to execute on volunteer time. The challenges include producing a unique identity for the application, providing easy to use controls for the parameters of the application, and providing interesting ways to visualize the data within the application. Additionally, existing toolkits produce technical issues when embedding within plugin hosts. MRuby-Zest is a new toolkit that was build while the ZynAddSubFX user interface was rewritten. This toolkit possesses unique characteristics within open source toolkits which target the problems specific to audio applications.

MRuby-Zest was created to address long standing issues in the ZynAddSubFX user interface. The MRuby-Zest framework was built with 5 characteristics in mind. MRuby-Zest should be:

  1. Scriptable: Implementation uses a first class higher level language

  2. Dynamically Resizable: Fluid layouts which do not have any fixed sizes

  3. Hot Reloadable: Reloads a modified implementation without restarting

  4. Embeddable: Can be placed within another UI without conflicts

  5. Maintainable: Relatively simple to read and write GUI code

To do this MRuby-Zest takes Qt’s QML language, replaced the scripting language with Ruby, integrated it with the nanovg OpenGL rendering library, and began to leverage parameter metadata that ZynAddSubFX produces via the rtosc library. Building the toolkit within Ruby instead of on-top of a pre-existing C/C++ toolkit has made MRuby-Zest particularly flexible when it comes to expanding it’s feature-set.

There will also be a social event again on Thursday evening.

There are also plans to have a hackfest the weekend right after the conference.

We hope to see you in Edinburgh!
