LOUIS
The effects engines built for Larry Seyer Drums and IDA, packaged as standalone plugins for any DAW — the same processing, the same voicing, outside the instrument that first needed it.
The Idea
Larry Seyer Drums and IDA grew their own effects because nothing off the shelf did quite the right thing — a compressor that travels continuously between characters instead of offering a menu of them, a reverb derived from measurements of real spaces, a tape stage that models the magnetics rather than sampling the result. Those engines were built for a drum instrument, but nothing about them is drum-specific.
LOUIS is that work made available on its own: the same engines, unmodified, wrapped so they load on any track in any session. Nothing is reimplemented for the standalone versions — they compile the same source Larry Seyer Drums does, so a mix built with one behaves identically in the other.
The name is an acronym — Linear, Organic, Unified, Interpolated, Synthesis — which describes the approach the suite is built on: rather than offering a menu of discrete presets to pick between, each plugin travels continuously through the space those presets would occupy. It is the same instinct that produced the SeyerMorph sampling engine, applied to effects.
The Suite
- SeyerCompA single always-stereo dynamics engine that morphs continuously through eight classic compressor characters along one signal path
- SeyerReverbA living algorithmic reverb whose coefficients derive from measurements of real acoustic spaces, reaching rooms that could not physically exist
- SeyerTapeAlgorithmic analog-tape coloration: magnetic saturation, tape-speed emphasis, wow and flutter, and program-dependent noise
- SeyerDistA distortion in its own right, with a character sweep running from fuzz through grind and crunch to warm
- SeyerAmpA guitar amplifier and speaker solved together, competing on feel and response rather than static tone
- SeyerSamplerThe instrument of the suite: a multi-timbral sample player built to play between an instrument's dynamic layers
Built as VST3, AU, CLAP, and AUv3 for macOS, Windows, and iOS. The suite is designed to grow well past these — the naming convention exists because there are a lot more coming.
