Sustenato Pedal

A VST Plugin that provides infinite piano-like sustain, using transient detection, autocorrelation, a phase vocoder and more.

Features:

Infinite sustain - let your notes and chords ring out for as long as you like.
Fade In/Out - adjust the speed at which the sustain fades in/out.
Wet/Dry - adjust your mix.
Layering - select however many layers you want to stack sustained notes and chords.
Compatible with any Keyboard-emulating foot-switch/pedal - control the sustain with your feet, as you would an FX pedal.
INCONSISTENT Works with trills and vibrato
Force Period - Uses a phase vocoder to stretch recorded samples to the set period. Wait less time before pressing the pedal.
- Not compatible with trills and vibrato

Best used as a live tool, whether for a live performance or recording
Having a foot-switch/pedal is not necessary, but highly recommended (as you use your hands to play the instrument)
Not tested as a post-processing tool
Easiest to set it up in a VST Host

Place the VST plugin anywhere in your plugin chain.
Open the plugin's editor window and ensure it is in focus whenever you want to use it
- If the window is not in focus, it will not receive keyboard events, hence you won't be able to toggle the sustainer using a keyboard key/foot-switch/pedal
Upon playing any note/chord, press your corresponding sustain keybind
- If you press it too quickly after playing, the sustained sound may not be clear/smooth. This can be used intentionally to create different effects, or can be reset quickly by re-triggering the keybind, given no new notes are played.

Designed for use with Electric Guitars and Amp Sims.

Works with Windows. Not tested, but it should work on Linux/Mac as well.
