Experimental audio projects built to interact with data from multiplayer music collaboration app Endlesss. OUROVEON is a set of interconnected apps, built from modular components around an evolving, homebrew "Endlesss SDK" (as an official SDK does not exist, nor does a sanctioned API). One part a learning exercise in lower-level audio coding and one part laboratory for ideas that build upon Endlesss' particular data model.
These tools and all code within are not affiliated with or endorsed by Endlesss Ltd. Use at your own risk.
While considered in perpetual beta, hundreds of hours of development, testing and play have gone into their development. Hopefully they should give you a robust, lean and fun way to interact with all the music you've made on Endlesss.
They are mature enough to have been used to help create published albums, such as both This Twilight Garden and its Second Volume by oddSTAR as well as the less-polished-but-certainly-still-technically-music Horse Science Sessions.
Pre-built releases are available for
- Windows - x86_64, Windows 8.1 or later
- MacOS - *Universal, Catalina (10.15) or later (notarised, signed, ready to run)
Privately we additionally build and test on Ubuntu Linux 23.04
Shared Features
-
$\textcolor{orange}{\textsf{Endlesss Power}}$ ~ The custom SDK provides comprehensive support for many facets of Endlesss' services, including- Authenticated sign-in, or fallback to a limited API set using public endpoints
- Support for Endlesss' lossless mode (as of v0.8.0)
- Comprehensive jam browser, offering a users' subscribed jams, solo jam, all current publics and a huge archive of previous open/public jams stretching back
- Shared Riff feed parsing
- Audio data from Endlesss is stored as-is in a trivially auditable offline stem cache for fast playback and archival
- Support for full archival / restoration of stem and database data per-jam, allowing for backup or trading of entire jam datasets
- Deals with quirky and damaged Endlesss data, all the way back to the earliest jams in 2019
- Built in retry/adapt fixes for unstable networks or servers
-
$\textcolor{orange}{\textsf{Audio Engine}}$ - Lean audio mixers built on PortAudio
- High-quality resampling using r8brain
- Beat-analysis and energy estimation via Qlib, driving UI and OpenGL shader-based visualisers
- Support for FLAC and Ogg Vorbis source formats
- Support for FLAC and WAV output - 9 simultaneous, asynchronous streams (depending on your hardware)
- (Windows Only) VST effect hosting & automation
- (Windows Only) IPC real-time exchange of mixer state, beats, energy, jammer names, etc
-
$\textcolor{orange}{\textsf{UI Rendering}}$ - Cross-platform front-end using GLFW
- Layout and controls running on Dear ImGui
Endlesss is incredible for making a lot of music, quickly. It's really terrible at navigating back through that music, finding what you want and getting it exported for use elsewhere. LORE was born to comprehensively solve these issues as well as offering an opportunity for long-term offline archival with easy storage & browsing of years' worth of music.

Features
-
$\textcolor{orange}{\textsf{Built For Scale}}$ ~ Download and synchronise even the largest (techno) jams on the platform. Navigating through 50,000+ riffs in LORE is a breeze, offering various data visualisation systems and username-searching. -
$\textcolor{orange}{\textsf{Built For Speed}}$ ~ Rapid and durable even on older, limited hardware. Fully multithreaded. -
$\textcolor{orange}{\textsf{Local Ownership}}$ ~ Download, explore, tag, export & archive your Endlesss music forever, even if the Endlesss cloud service disappears. -
$\textcolor{orange}{\textsf{Song Sketching}}$ ~ Pick and instantly play any riff, build simple sequences with transition timing, create bookmarks to help plan future tracks and exports. -
$\textcolor{orange}{\textsf{Open Data Formats}}$ ~ Everything is stored in easy-to-readsqlite3or JSON, trivially accessible or extended by other 3rd party tools.
Get the very best out of your live Endlesss performances
NOTE: BEAM has not been actively developed recently as LORE has taken priority. It may end up being heavily refactored.
BEAM connects to a chosen jam, watches for changes, syncs live stems and produces a high-quality broadcastable mix. Additionally use a websocket connection (including from LORE) to push arbitrary riff sequences for blending.
Features
-
$\textcolor{orange}{\textsf{Smooth Riff Transitions}}$ ~ with configurable blending and timing. no more glitchy hard cuts at weird times between riffs. -
$\textcolor{orange}{\textsf{Multitrack}}$ ~ record all 8 channels to individual FLAC outputs on disk, live -
$\textcolor{orange}{\textsf{Performance Compression}}$ ~ for multitrack; reduce repetition in final recordings by ensuring each riff gets at most one full loop before recording is paused
BEAM has so far broadcast over 50 hours of jam sessions without missing a beat, including running for a sustained 24-hour live set.
The BEAM live visualisation sync functionality over IPC was used along with the NESTDROP visualiser and the Unity 3D engine to broadcast this hour-long jam
OUROVEON is written in C++20, built using Premake.
