PhantomTrack
Notes Nobody Played

A second voice, in key, answering the one you recorded — played by no one. Slide one pad from airy shimmer to a room-filling bed.

Living harmony and texture built from your own sound, not random notes. It follows your pitch, note for note.

Hear the Phantom Layer

PhantomTrack on the lead of “Dark Good Time”. It grows a pitch-tracked ghost voice from the track — flip through the four corners of the XY pad.

Music: xeniclex · loudness-matched A/B, rendered in a real DAW.

PhantomTrack interface — XY pad morphing between the four phantom characters over a live phantom-cloud visualization

One XY pad morphs between the four phantom characters — Whisper, Poltergeist, Abyss and Monolith — over a live phantom-cloud visualization.

A Second Voice You Never Recorded

Feed it a vocal, a guitar, a synth or a whole bus. It tracks the pitch and grows harmonies and textures that follow your part, in key.

🎵
Harmonic cloud
The phantom notes themselves — pitch-tracked voices that shimmer in tune above and around your source, re-voiced from its own spectrum.
🔁
Rhythmic echo
Cross-source stutters and grains that re-trigger the phantom in time, turning transients into restless, evolving rhythm.
🌫️
Spectral wash
The resonant tail those notes leave behind — a slow, tonal drone you can key with a Root Note and hold with Freeze.

It's not a reverb and it's not a delay. It's a phantom-note engine that turns what you played into what you didn't.

It Follows Your Pitch, In Tune

The pitch tracker locks onto your part; the phantom voices stay in key above and around it, moving as you move.

Everything You Need

🎵
Pitch-Tracked Phantom Notes
A real-time pitch tracker drives a harmonic cloud of voices that follow your melody in tune — phantom notes re-voiced from your own signal.
🎚️
One XY Pad, Four Characters
Morph between Whisper, Poltergeist, Abyss and Monolith on a single pad — from airy crystal shimmer to dense cinematic drone, and everything between.
🔗
Send / Receive Across Tracks
Instances share a phantom layer over shared memory. Send one track's signal to the pool and grow its phantom notes on a completely different track.
🎛️
Deep Advanced Controls
Character, Saturation, Darkness, Ducking, Stereo Width, Predelay, Wash LP, Freeze + Freeze Tone, Root Note and tape-style Wow — automatable in any host.
❄️
Freeze & Key Control
Hold a chord with Freeze and key the wash to a Root Note so the phantom layer always sits musically under your track.
🖱️
Resizable Interface
Drag the corner grip to resize; the size is saved per project, with a live phantom-cloud visualization and a contextual help bar.

Where It Shines

🎤
Lead Vocal
Every note you sing is doubled by a shimmering, in-tune ghost ensemble — instant ethereal backing voices with Whisper.
🎸
Guitar / Synth / Arp
Abyss grows a sympathetic-resonator drone from the notes you play; Monolith turns a simple line into a dense cinematic bed.
🥁
Drums & Percussion
Poltergeist chops transients into saturated, stuttering rhythmic grains that lock to the groove.
🎬
Bus & Film Cue
Set a Root Note, freeze a chord, and let the phantom layer hum under the whole mix as an evolving underscore.

In Their Words

Fantastic plugin, instant classic for me! I use it when I want to add some in-key background to an existing track where a harmonizer would be too much or feels too static.

🪟 Windows users — SmartScreen or antivirus warning? Click here

The Windows installer is not code-signed, so SmartScreen may say the publisher is unknown, and a brand-new installer occasionally trips an antivirus heuristic. Neither is a detection — it is a reputation score that every unsigned release starts from zero.

  1. Click "More info", then "Run anyway"
  2. Or skip the installer entirely: the .zip above contains the same VST3 and CLAP files — copy them into C:\Program Files\Common Files\VST3\ and C:\Program Files\Common Files\CLAP\

macOS

Nothing to do. The disk image, the installer and all three plugin bundles are signed with an Apple Developer ID and notarized by Apple, with the ticket stapled into the files so it works offline. The publisher shows as Tony Cuny — the legal name behind Xeni Audio, which is what Apple puts on the certificate. Logic loads the AU with no workaround.

Free demo, no sign-up required. PhantomTrack no longer requires AVX2 — it now runs on any x86-64 processor, including AMD FX/Phenom and Intel chips from before 2013, where hosts used to scan it forever. Also fixes the editor window failing to open on Windows over Remote Desktop, in a virtual machine or without a GPU driver, and window sizes not being remembered when set from the host's window frame. The sound is unchanged. After download, refer to the included README.txt and the PDF manual for installation — the manual is also readable online. Questions? support@xeni-audio.com

Changelog

Latest: v1.1.2all versions

1.1.21 Sep 2026

  • No longer requires AVX2 — runs on any x86-64 CPU, including older AMD and pre-2013 Intel.
  • Windows: fixed the editor failing to open over Remote Desktop, in a VM, or with no GPU driver.
  • The window keeps the size you set from the host's frame — the path that matters in Cubase and Nuendo.

1.1.110 Aug 2026

  • Fixed a crash in Cubase and Nuendo (Windows) when dragging the resize grip.
  • In those two hosts the grip is inert — resize from the host's own window frame.

1.1.08 Aug 2026

  • Fixed a project loading with PhantomTrack silently bypassed after a parameter was added.
  • Demo mutes now line up across instances; activating one instance unlocks the others.
  • macOS installer signed and notarized by Apple; AU resize fixed in Reaper and Luna.

0.9.015 Jun 2026

  • First release-candidate build: three phantom engines, XY morph pad, post-mix shaper, presets and licensing.
