Deriva is a sound-design plugin about unstable preservation. You do not build a preset by moving every parameter manually; you generate a Fragment, listen to what the Engines reveal, and decide whether to risk it before The Keeper. Some sounds survive as Remnants. Others are lost.
Deriva is a sound-design instrument built around influenced randomness. Press Fracture to generate a temporary Fragment, shape the result through the four Engines, then Offer it to The Keeper. If The Keeper preserves it, the Fragment becomes a Remnant and is stored in the Archive.
Audio passes through normally until a Fragment exists.
Deriva generates new hidden Engine parameters and visible tag values.
The Fragment becomes active and the Engines process incoming audio.
The current Fragment is submitted to The Keeper.
Preserved saves a Remnant. Lost discards the Fragment.
While The Keeper is deciding, or while Preserved/Lost is being shown, Fracture is temporarily unavailable. This prevents replacing the Fragment during the decision window.
ErosionSaturation, tone damage, drive and destructive colour.
ScatterGranular clouds, octave fragments, texture and suspended motion.
VeilCreative filtering, resonant movement and spectral colour.
MirrorAmbient shimmer, reverse bloom and wide ethereal reverb.
Each Engine is described by a level tag. Tags are calculated from the Engine parameters and Mix, so they describe effective sound strength rather than just raw parameter values.
Vessels are fixed Archive categories for organising Remnants without changing their sound. A Remnant can be assigned to Default, Vocals, Drums, Bass, Pads, Atmos, Texture or Ruined. Use the Vessels button in the Archive to filter the list; no selected Vessel means the Archive shows every Vessel.
Remnants include a Keeper signature. If a saved Remnant is manually edited outside the plugin, it stays visible in the Archive but becomes invalid and cannot be recalled.
Normal Remnants can use up to 100% Mix. When a Flowing Offer is Lost, the source Remnant loses 10% from its own maximum Mix. When moving from a limited Remnant to another Remnant with a higher maximum, Global Mix rises to that new maximum; when moving to a lower maximum, it clamps down. Host automation for Global Mix is also clamped to the active Remnant's maximum.
Mirror exposes an optional external sidechain input in supported hosts. Route another track into Deriva's sidechain to duck only the wet reverb tail; the dry input still feeds Mirror normally, while the ambience moves out of the way when the sidechain signal is present.
When the DAW bypasses, disables or suspends Deriva, the interface fades into a BYPASSED view. Some hosts report this through a bypass callback, while others are detected when audio callbacks stop arriving.
Deriva's audio processing and Archive are local. The plugin does not need internet access to make sound, load Remnants or preserve new ones. Internet is only used by external links and update checking.
Remnants are saved in a local Deriva archive file on the user's machine and are also stored with DAW sessions. The persistent Archive is designed so removing and re-adding the plugin does not erase preserved Remnants.
Check Updates compares the installed version with the latest version published on the Deriva download site. When a new build is available, Deriva shows a Download button that opens the current Mac or Windows installer link. Installing a new version should replace the plugin binary while keeping the user's local Archive.
