The cloud-5 system is a toolkit and library designed for creating computer
music that is hosted on Web servers and that runs and plays in the user's Web
browser. In theory, that can be any current Web browser, even on smartphones
and tablets, although performance might be an issue on less powerful systems.
For examples of such music, see
cloud-music.

The cloud-5 system is based on
my own WebAssembly builds of Csound and CsoundAC. Some pieces may use
third party libraries. The home page of Csound itself is
here.

Code written as part of cloud-5 is licensed under the terms of the same
license as Csound, the
GNU Lesser Public License, version 2.1.
Components and libraries used by cloud-5 come under a variety of open source
licenses; see the links to individual packages for more information.

Introduction

The cloud-5 system is designed for making sophisticated computer music purely
in the HTML5 environment. The system is especially suited for pieces that play
online, for pieces that play indefinitely, for visual music, for algorithmic
composition, and for live coding.

cloud-5 runs on every system with an audio output that can run a Web server
and a standards compliant Web browser. That includes all computers
running macOS, Linux, or Windows, as well as the more powerful smartphones and
tablets.

Release Notes

v2.0

• Moved cloud-5's Web root directory from cloud-5 to
  cloud-5/strudel/website/dist. This makes it possible to integrate
  Strudel, Csound, and CsoundAC without any patches or other modifications of
  Strudel source code.

• Added one-time singleton creation code for Csound and CsoundAC to
  csound_loader.js.

• Simplified the integration of Csound, CsoundAC, and Strudel by ensuring
  that Csound and CsoundAC exist as fully initialized global objects in the
  JavaScript context (as globalThis.csound and globalThis.csoundac),
  before any HTML elements run.

• Updated documentation for running cloud-5 pieces in NW.js.

• Many bug fixes:

  • Enable editing in dat.gui text fields.
  • Ensure that opening the Controls menu does not affect the layout of other elements.
  • Toggle showing piano roll/hiding shader with showing shader/hiding piano roll.
  • Fixed logic for diagnostic levels in statefulpatterns.mjs.
  • Removed Record button and handler, and other dead code.
  • Removed unnecessary files.
  • Clarifed source code in cloud-5.js.
  • Enabled rendering to soundfile in NW.js.
  • Enabled running Strudel in NW.js.

v1.1.1

Corrected instructions in README.md for deployment.

cloud-5 version 1.1

• Made a clearer distinction between the Web site serving showcase for
  cloud-music pieces, and the README.md for the cloud-5 system.

• Added a global menu with a curated list of better pieces.

• Improved layouts to deal with presence/absence of global menu.

Computer music in the cloud by Michael Gogins

This is computer music that is hosted online, but actually rendered in Web
browsers. The pieces are not soundfiles and they are not streamed. Each piece
is a Web page that contains embedded software that runs in the browser to
synthesize the music. Most pieces will play indefinitely. There may or may
not be animated visuals along with the music. The listener may or may not be
able to control and/or customize the piece -- perhaps quite a bit, amounting
to a new piece, co-composed with me.

For more information on most of these pieces, open the piece and view its
About tab, or use the browser's inspector to view the underlying
code.

• Scrims, a JavaScript piece that samples an animated WebGL
  hopalong fractal to obtain notes that are then harmonized using CsoundAC's
  chord space operations.
• Cloud Music No. 1.
• Cloud Music No. 2.
• Cloud Music No. 3.
• Cloud Music No. 4.
• Cloud Music No. 6.
• Cloud Music No. 8.
• Cloud Music No. 9.
• Cloud Music No. 14. This one has a button so the
  user can record a performance and download the resulting soundfile.
• 2024-ICSC, prepared for the 2024 International Csound
  Conference in Vienna. This is the same as Cloud Music No. 14, except that
  the "Full screen" menu item moves compositional controls onto a
  second monitor for unobscured visuals.
• Cancycle. Set up to enable live coding.
• Polymetric.

cloud-5

The cloud-music pieces are implemented using my cloud-5 system for creating
computer music that runs in Web browsers. This in turn is based on
my own WebAssembly builds of Csound and CsoundAC.
Some pieces may use third party libraries. The home page of Csound itself
is here.

Code written as part of cloud-5 is licensed under the terms of the same
license as Csound, the
GNU Lesser Public License, version 2.1.
Components and libraries used by cloud-5 come under a variety of open source
licenses; see the links to individual packages for more information.

Introduction

The cloud-5 system is designed for making sophisticated computer music purely
in the HTML5 environment. The system is especially suited for pieces that play
online, for pieces that play indefinitely, for visual music, for algorithmic
composition, and for live coding.

cloud-5 runs on every system with an audio output that can run a Web server
and a standards compliant Web browser. That includes all computers
running macOS, Linux, or Windows, as well as most Android devices.

For recent changes, see the Release Notes at the end of
this document.

Getting Started

Pre-requisites

• A Web server that will run from a configurable directory in which you can
  read, edit, and write files. On most systems, the simplest way to get a Web
  server is to install Python 3.

• A standards-compliant Web browser (currently, that includes nearly all Web
  browsers). Should already exist on your system. On Android, install a Web
  server app such as
  Phlox.

• A text or code editor for writing your compositions. A simple text editor
  should already exist on your system. I use
  Visual Studio Code myself, as it is very
  powerful and yet easy to customize. On Android, install a text editor such as
  QuickEdit Pro.

Installation

There is no installation! Simply download the release, and unzip it into a
cloud-5 directory.

cloud-5 can be stored on a USB thumb drive, and will run with all functionality
from the thumb drive. This makes it possible to carry all of your work in
progress from computer to device to computer.

Or, simply copy the entire cloud-5 directory with all contents to your computer
or device. Make sure you can execute, read, edit, and write files in your
cloud-5 directory.

Configuration

There is no configuration!

Well, actually there might be one thing. You might need to configure your
local Web server to serve files from your cloud-5 directory.

Running

1. Start a local Web server to serve the cloud-5 directory. The easiest way
   to do this on most systems is to open a terminal, change to your cloud-5
   directory, and execute python3 -m http.server.

2. Start your Web browser, and navigate to your cloud-5 Web site (usually
   just something like https://localhost:8000). Some users have problems
   with Firefox, e.g. with WebMIDI permissions. If you experience this, try
   the Chrome browser.

3. You should see this README as a Web page. Click on
   cloud_music_no_1.html and verify that you see
   animated graphics, and can play and hear the piece.

4. Some cloud-5 pieces use the dat.gui library to create a popup menu of
   controls for Csound instruments or other purposes. You can create new
   presets, and you can get the Web browser to remember the current preset
   parameters in local storage. If you need to revert to the hard-coded
   parameters in a piece, clear local storage in the browser settings, or
   in the browser's debugger.

Making Music

In cloud-5, musical compositions are written as Web pages, i.e. as .html
files.

It's a good idea for each composition to be written as just one .html file.
It must be in your cloud-5 directory. Any Csound orchestra code, JavaScript
code, and GLSL shader programs should simply be embedded in the HTML file in,
e.g., template strings (string literals) in JavaScript code, or included as
<script> or <textview> elements.

There are many ways to write compositions, because the capabilities of Csound,
Strudel, and HTML5 are so vast. Start out by a making a copy of one of the
examples below, and edit it to suit your own purposes.

Tutorial Examples

These are pieces designed to show how to use the new architecture for cloud-5
based on cloud-5.js, a library of resuable Web components that greatly
simplifies writing cloud music pieces.

• cloud5-example-simple.html: a very simple
  composition that illustrates my paper on cloud-music.

• cloud5-example-score-generator.html:
  a fixed-length piece with a score generated by CsoundAC, with an animated
  piano roll display and audio visualization.

• cloud5-example-parametric-lindenmayer.html:
  a fixed-length piece with a score generated by a parametric Lindenmayer
  system, with an animated piano roll display and audio visualization.

• cloud5-example-strudel.html: always-on
  music produced by a Strudel patch, with audio visualization. This piece is
  live-codeable.

• cloud5-example-visual-music.html:
  always-on visual music produced by a GLSL shader that is sampled and
  shaped using CsoundAC.

Other Examples

• A minimal example that just plays an embedded Csound piece.

• A Csound Player that will play, and let you edit, any
  Csound piece that you paste into the text area.

• Message from Another Planet, a Csound piece with a basic
  HTML user interface.

• Strudel REPL, exactly the same as the main Strudel Web
  site.

• Trichord Space, an interactive piece that displays
  Dmitri Tymoczko's chord space for trichords, with the ability to perform,
  hear, and visualize various operations on the chords in the space.

Components

• Csound version 6.18, one of the oldest and most
  powerful sound programming languages, compiled for WebAssembly to run in
  Web browers in csound-wasm.

• CsoundAC, my C++ library for
  algorithmic composition with Csound, compiled for WebAssembly to run in
  Web browsers in csound-wasm, and
  incorporating my implementation of mathematical theories of chord space and
  neo-Reimannian operations, and scales and functional harmony, by
  Dmitri Tymoczko.

• A collection of predefined Csound instrument definitions by me from
  CsoundAC.

• Strudel, a JavaScript port of the
  widely used live coding system Tidal Cycles, by
  Alex McLean, Fel...

cloud-5 version 1 beta 2

This is a generic update release reflecting experience in making compositions with cloud-5.

cloud-5 version 1 beta

This is the first full release of the cloud-5 browser-based computer music system, which enables writing sophisticated computer music compositions that run in Web browsers and can use browser-based Csound, Strudel, and CsoundAC.

• The code has been refactored into a cloud-5.js file that defines custom HTML elements and code for simplifying the writing of cloud-5 compositions.
• Examples have been added that illustrate the use of these custom elements.
• API documentation has been added.
• The release now includes a production-ready cloud-5.zip. Download this archive, unpack it into a directory, and run a local (or other) Web server in that directory. One can then immediately run the examples in your Web browser or create new compositions in that directory. There are no external dependencies.

For more information, see README.md or the jsdocs.

This is a beta release. Please enter any bugs, comments, or requests in the GitHub issues for this repository.

Introduction

Welcome to cloud-5, a system and toolkit for making sophisticated computer
music purely in the HTML5 environment! The system is especially suited for
pieces that run online, for pieces that play indefinitely, for visual music,
for algorithmic composition, and for live coding.

cloud-5 runs on every system with an audio output that can run a Web server
and a standards compliant Web browser. That includes all computers
running macOS, Linux, or Windows, as well as most Android devices. It is also
possible to run cloud-5 on single-board computers (SBCs) such as Bela,
Norns, BeagleBoards,
Raspberry Pi, and others. However, running
cloud-5 on a SBC requires installing at least a Web server (and probably also
a Web browser) on the device. Most users without special need for a SBC (such
as an installation or kiosk) will be better off just using a personal
computer.

cloud-5 is used by my own Web site of "always-on" computer music pieces,
cloud-music.

For recent changes, see the Release Notes at the end of
this document.

It also is possible to run cloud-5 pieces locally in NW.js
using csound.node. In this
case, csound.node provides a native code build of Csound, and such pieces can
load native code plugins and read and write to the local filesystem.

Components

• Csound version 6.19, one of the oldest and most
  powerful sound programming languages, compiled for WebAssembly to run in
  Web browers in csound-wasm.

• CsoundAC, my C++ library for
  algorithmic composition with Csound,
  compiled for WebAssembly to run in Web browsers in
  csound-wasm, and incorporating
  my implementation of mathematical theories of chord space and
  neo-Reimannian operations, and scales and functional harmony, by
  Dmitri Tymoczko.

• A collection of predefined Csound instrument definitions by me from
  CsoundAC.

• Strudel, a JavaScript port of the
  widely used live coding system Tidal Cycles, by
  Alex McLean, Felix Roos, and others. Note: cloud-5 makes several
  necessary patches to the Strudel source code and distribution.

• Of course, a standards-compliant Web browser, which has an awesome set of
  capabilities, including the most widely used programming language,
  JavaScript, which can call Csound, CsoundAC, and Strudel.

Capabilities

• High-resolution, sample-accurate sound synthesis using one of the largest and
  most capable libraries that exists for synthesis and signal processing, the
  Csound opcodes.

• Interactive live music coding using the domain-specific, real-time music
  programming language Strudel; this includes a neat animated piano roll
  display of the notes from the music that is playing.

• Control of Csound from Strudel. This includes both real-time notes
  generated by Strudel patches for the csound and csoundm outputs, and
  real-time control channel values created by Strudel Patterns, including the
  new slider widget.

• MIDI input and output from Csound and Strudel.

• Open Sound Control input and output from Csound and Strudel.

• Several systems for time-frequency analysis/synthesis, from Csound, including
  Victor Lazzarini's
  phase vocoder streaming
  (PVS) opcodes.

• Several high-fidelity sample players, from Csound
  (Fluidsynth opcodes)
  and Strudel (superdough).

• High-resolution, three-dimensional, animated computer graphics using
  WebGL and/or OpenGL Shader Language (GLSL), from the Web browser.

• All of the staggering panoply of capabilities that are built into every
  standards-compliant Web browser, see HTML5 Test.

Running in the Browser

Limitations

The major limitation of running in the browser is that csound-5 pieces are
sandboxed, and cannot write to the file system. In other words, cloud-5
cannot write soundfiles, or any other kind of files. That means all audio is
streaming audio.

However, it is possible to use an audio loopback driver such as
BlackHole to route
audio produced by cloud-5 to a digital audio workstation that can write
soundfiles. The maximum resolution of such soundfiles is floating-point
samples at 48 KHz, significantly higher resolution than the CD format.

To set this up on the Mac, open the Audio MIDI Setup app, click on the + at
the bottom, and click on Create Multi-Ouput Device, including both your
standard audio output and BlackHole. Then, in the Sound settings, select that
Multi-Output Device as the default output. Finally, in your DAW or recording
software, select BlackHole as the audio input device.

Getting Started

Pre-requisites

• A Web server that will run from a configurable directory in which you can
  read, edit, and write files. On most systems, the simplest way to get a Web
  server is to install Python.

• A standards-compliant Web browser (currently, that includes nearly all Web
  browsers). Should already exist on your system. On Android, install a Web

  should already exist on your system. I use
  SciTE myself as it is very
  lightweight and yet very easy to customize. On Android, install
  a text editor such as

Release Notes

v0.1beta6

• Introduced the CsoundAC track function, a variant of Strudel's arrange
  that does not crash when the number of cycles for a section is set to zero
  to silence it.

• Improved the CsoundAC csoundn output to send all control parameters
  with names beginning gi or gk to Csound as control channel values;
  these channels must first be set up in the Csound orchestra with the same
  names.

• Added cancyle.html, a piece designed for live performance by doing a
  modest amount of live coding during play.

v0.1beta5

• Updated Strudel to get the extremely useful slider, which can be either
  discrete or continuous. The slider is embedded directly into the Strudel
  patch.

• Added some code to csoundn that sends the value of any Strudel control
  registered with createParam and whose name begins with gi or gk to
  Csound as a control channel value. This also means that the new slider
  widget in Strudel can send its value to the Csound control channel.

v0.1beta4

• Attempts have been made to correct the scheduling of the csoundn output
  based on a trigger, and to get csoundn to output correct piano roll
  events.

• Put in diagnostic messages marked sync for testing.

• Colorize notes in the piano roll that come from csoundn.

• In package.json always make a releasable zip file in each build.

v0.1beta3

• Put in needed patch for cyclist.mjs.

• Restored concatenated Strudel controls string in csoundac.mjs.

v0.1beta2

• Improved README.md/index.html.

• Corrected broken links and incorrect credits in example pieces.

• Replaced the favicon from Strudel with cloud-5's own favicon.

v0.1beta

• This was the initial release.

Introduction

Welcome to cloud-5, a system and toolkit for making sophisticated computer
music purely in the HTML5 environment! The system is especially suited for
pieces that run online, for pieces that play indefinitely, for visual music,
for algorithmic composition, and for live coding.

cloud-5 runs on every system with an audio output that can run a Web server
and a standards compliant Web browser. That includes all computers
running macOS, Linux, or Windows, as well as most Android devices. It is also
possible to run cloud-5 on single-board computers (SBCs) such as Bela,
Norns, BeagleBoards,
Raspberry Pi, and others. However, running
cloud-5 on a SBC requires installing at least a Web server (and probably also
a Web browser) on the device. Most users without special need for a SBC (such
as an installation or kiosk) will be better off just using a personal
computer.

cloud-5 is used by my own Web site of "always-on" computer music pieces,
cloud-music.
