Please visit the website for the complete usage guide, module reference, and setup details.

Envion is an envelope-first ecosystem for algorithmic and procedural composition in Pure Data (Pd).
It redefines sampling as a gesture-based process: thousands of dynamic envelopes ("Dynatext triplets") continuously sculpt micro-events and temporal shapes.

The Net-Audio submodule fetches random sound atoms from online archives (Internet Archive, Wikimedia Commons, Freesound), transforming contingent data into acousmatic gestures.

Envion is open-source, compatible with PlugData on macOS, Windows, and iPadOS, and released under the MIT License (with Attribution).

• PlugData (includes cyclone and else)
• Mandatory Libraries:
  • ggee
  • audiolab
• Optional Libraries:
  • ceammc
  • simplex (for 3D visualization)

Open Envion_v4.5_Plugdata.pd in PlugData to play presets, tweak behavior, and load new samples.

Envion will not work if you only download the Envion_v5.1_Plugdata.pd file.
The patch depends on its full folder structure (/libs, /core, /utils, /netsound, /data, etc.).
You must download the entire repository.

1. Download the full repository ZIP
   https://github.com/aveniridm/envion/archive/refs/heads/main.zip
2. Unzip it — this creates a folder such as envion-main/
3. Do not move the .pd patch out of this folder
4. Open Envion_v5.1_Plugdata.pd from inside the same folder

envion-main/ Envion_v5.1_Plugdata.pd [core] [libs] [netsound] [utils] [data] [audio]

When the patch is moved outside its directory tree, PlugData cannot resolve abstractions or support files —
this results in silent loading, missing modules, or inconsistent behaviour.
Keeping the folder intact ensures everything loads correctly.

Once installed correctly:

• Turn on DSP
• Load the main master preset (large bang button on the right)
• Sound is immediate — no configuration required

Take your time to explore the deeper functions later —
for now, just play, listen, and discover.
Envion is designed so that sound emerges instantly, while depth unfolds gradually.

PlugData for iPadOS/iOS includes core libraries.
Optional libraries (ggee, ceammc, simplex, audiolab) add extra features but are not required for basic functionality.

If dependency warnings appear, they refer to optional libraries.
The patch remains operational without them, except for features such as 3D scope visualization.

Important:
The Net-Audio module is not functional on iPadOS as of this release.
Due to current limitations in PlugData for iPadOS/iOS, URL-based loading and fetching are not supported.
As a result, the Net-Audio module will remain inactive in the iPadOS version until the necessary functionality is implemented upstream.
A related issue has been opened in the PlugData repository; updates will be provided when support is available.

For detailed instructions and troubleshooting, refer to IPAD_GUIDE.md.

Envion operates by writing trajectories on sound through textual sequences of triplets (amplitude, duration, offset) sent to vline~.
Each line of a text file defines a gesture.
Thousands of these triplets, stored in the /data folder, create a reservoir of living envelopes.

Net-Audio extends Envion by automatically fetching sonic material from public archives.
Python scripts build .txt lists of direct URLs, which Envion reads and articulates through its envelope engine.
