Branch-Free Oscillators for Virtual Analog Software Synthesizer Applications in C++ - Angus Hewlett - ADC 2024
---

A discussion of techniques and approaches for building parallel branch-free oscillators for VA software synthesizer applications in C++ - exploring the stack from low-level machine instructions and CPU architecture up to signal processing concerns and language-level abstractions.

How can a branch-free design help you build more performant oscillators, how does it work underneath, and what are the advantages, disadvantages and potential pitfalls of this type of design approach?

If you're curious about CPU architecture and what's going on underneath your code, this talk will be an interesting window into that sometimes less-than-obvious world.

Workshop: Klang - Live and Expressive C++ for Audio - Chris Nash - ADC 2024
---

A practical introduction to Klang, a C++ dialect (language extension) for audio, and rapIDE (rapid audio prototyping IDE), a complete C++ development environment in a DAW plugin, supporting live code editing, recompiling, and debugging. Developed to improve the liveness and usability of professional DSP practices, both tools facilitate the expressive design of new interfaces, sounds, and audio processes, while lowering the threshold to C++ for newcomers and learners, without compromising its expressive ceiling or performance.

ABOUT THE WORKSHOP

The workshop will feature discussions, live demonstrations, structured practical exercises, and assisted open exploration of the Klang language and rapIDE development platform, both available free for non-commercial use.

ABOUT THE TECHNOLOGIES

The Klang language (http://github.com/nashaudio/klang) is a single header include, compatible with any C++17 enabled platform, transforming C++ into an audio programming language with rich support for audio types, processes, and DSP primitives - notably also adding support for concise, explicit expressions of signal flow, allowing C++ code to more closely mirror block diagrams

The rapIDE IDE (aka Klang Studio; http://nash.audio/klang/studio) is a suite of cross-platform (Windows/Mac) audio plugins (in VST and AU format) that contain a complete integrated development environment (IDE) based on the LLVM/clang toolchain, supporting live, in-plugin coding, compiling, hot-swapping, analysis, graphing, and debugging without stopping the host (or even playback). Designed for rapid prototyping of C++ audio processes (e.g. synthesisers, effects), rapIDE is designed to integrate with existing workflows, such as desktop, embedded, and web audio development, but also provide a more immediate and immersive way to explore sound with C++.

FURTHER INFORMATION

Both technologies are pre-release and under active development, maintained by nash.audio, a non-profit organisation supporting projects in music and technology. Delegates require a Windows or Mac laptop, and are recommended to download and install rapIDE (aka Klang Studio) from nash.audio/klang in advance of the session.

Chris Nash

Chris Nash is a software developer, composer, educator and researcher in things that go beep in the night. Following a PhD on music software design at Cambridge, he has worked on technology and music projects across academia and industry, including for the BBC, Steinberg/Yamaha, and multiple start-ups, and independently develops and maintains several software projects, specialising in computer music and making music programming more accessible, including Manhattan (a hybrid DAW/programming language), Klang (a C++ dialect for audio), rapIDE (a plug-in based C++ IDE) and reViSiT (an award-winning plug-in based sound tracker).

He is currently Senior Lecturer in Software Development for Audio, Sound, and Music at UWE Bristol, and recently founded nash.audio, a non-profit organisation supporting creativity and learning in music technology. Working with London-based Point Blank Music School, Dr Nash is the architect of the forthcoming MuSE (Music Systems Engineering) course, developed in collaboration with industry to be the world's first professional audio developer degree programme.

Introducing ni-midi2 - A Modern C++ Library Implementing MIDI2 UMP 1.1 and MIDI CI 1.2 - Franz Detro - ADC 2024
---

MIDI 2.0 implementations arrived in recent macOS and Linux versions, and Windows MIDI 2.0 support is expected to arrive end of 2024.

ni-midi2 is a modern C++ library implementing MIDI2 UMP 1.1 and MIDI-CI 1.2. The platform-independent library allows you to easily migrate your code to support MIDI 2, while maintaining compatibility to the traditional MIDI 1 protocol.

The talk will cover basic concepts of the library and real-world examples of how it helps you to achieve protocol-agnostic MIDI 2 support in your codebase.
