Description
CPHN OPTY
A free (for beta test stage) LA-2A-inspired Max for Live optical tube leveler.
CPHN OPTY is a stereo Max for Live Audio Effect built around slow, musical optical-style leveling, soft knee compression, program-dependent release, and warm tube/transformer-inspired color. It is not a circuit clone or trademarked hardware recreation, but it is designed around the classic optical leveling workflow: simple controls, smooth gain reduction, and a forgiving feel on vocals, bass, guitars, pads, and buses.
Main features
* Peak Reduction / Gain workflow
* Compress and Limit modes
* Program-dependent opto release with slow memory tail
* Parallel Mix control
* Stereo Link control
* Sidechain HPF: Flat, 60 Hz, 90 Hz, 150 Hz
* Color control for tube/transformer-style saturation and tone
* Optional subtle noise
* Power bypass
* Custom gain-reduction VU meter
* Compact Ableton-friendly UI: 500 x 160 px
Controls
* Peak Reduction: compression amount
* Gain: output makeup, unity around the default setting
* Compress / Limit: softer leveling or firmer peak control
* Mix: dry/wet blend
* Color: harmonic density, low-mid weight, and high-frequency rounding
* Link: stereo detector linking
* HPF: reduces low-frequency pumping in the detector
* Noise: subtle analog-style noise
* Speed: slow, normal, fast opto timing trim
Notes
This is a musical LA-2A-style optical leveler, not a circuit-level hardware clone. The T4-style release behavior, tube color, and transformer tone are DSP approximations designed for musical use inside Ableton Live.
