VST3 Rhythmic Sound Transformer
AETHER
Turn sustained sound into a living phrase.
An incoming-audio effect for rhythmic articulation, harmonic movement, and echoes. Formerly SEQUA; existing presets and plugin identity are preserved.

AETHER guide
Getting started.
Insert AETHER after your instrument or audio return. Fresh instances open Moog Pocket in Focused mode. Choose a phrase pattern and shape the groove with Rate, Shape, Groove, Evolution, Harmony and Mix.
Open Details for Length, Body preserve, Attack preserve, Voices, Build, Ratchet, Lift and Echo. Start Harmony and Echo at zero to hear the core rhythm. Build develops faster pulse grids; return it to zero to relax.
There are twelve focused presets plus twelve original presets. Existing pre-1.5 saved states restore Legacy processing automatically. Original parameter IDs and factory indices remain; new controls are appended for controller compatibility.
Interface version 1.5.0. These notes describe the current build.
