The architecture behind the archive
A living cathedral for tracker and chip music.
Ploppbox routes more than 103 source formats through dedicated replay engines, then turns every pattern, register write and synthesized voice into a live visual space.

Replay architecture
One archive. Eight purpose-built signal paths.
Ploppbox does not force unrelated formats through one decoder. The router inspects each source and hands it to the engine designed for its musical system.

Live archive intelligence
The cathedral is continuously rearranging itself.
Every play changes the archive’s gravity. Recent signals surface in real time, while enduring modules accumulate their own orbit.

Artists shaping the archive
How the signal becomes space
Source-faithful replay, isolated from the interface.
The visual layer never pretends to be the music engine. Replay, buffering, transport and rendering remain separated so one format cannot destabilize the rest of the cathedral.
Inspect
Identify the source
Extension, path context and file content select the correct replay lane.Isolate
Wake the engine
Workers and AudioWorklets keep emulation and decoding away from the interface.Normalize
Shape the signal
Transport, loudness and subsong state are exposed through one player contract.Visualize
Build the architecture
Frequency, energy and time drive the live Signal Cathedral renderer.The preservation principle
“Tracker and chip music deserve a stage, not a progress bar.”
These files are not merely audio containers. They are compact programs, pattern systems, instrument instructions and hardware conversations. Ploppbox preserves that structure by replaying the source whenever a local engine can do so.
The archive is awake
Choose a signal and step inside.
424 817 indexed tracks, 103 playable formats and no prescribed path through them.
