Sparklelizer
A stereo delay that shows each repeat as it moves across the beat.
- Two delay lines on two note divisions of one tempo, cross-feeding into each other
- Bounce Scope: the repeat train drawn on a beat grid before you hear it
- Tone shaping inside the loop, so repeats thin and darken as they age
- Width, bloom and a duck from the dry input, on the wet path only
- A post-delay chain in the same plugin: reverb and saturation with one amount each, and a compressor with Threshold, Ratio and Makeup
- The compressor runs last, where its makeup gain brings the delay feedback up in volume
- The factory bank Jazz voiced, including the settings from her own sessions
Bounce Room
Dry drums and flexible MIDI loops made to leave room for repeats.
- A sampled drum kit voiced for delay, with short dry hits that leave room for repeats
- 64 four-bar MIDI drum loops across straight, 16-beat, dance and Latin feels
- General MIDI mapping for the included kit or any drum plugin you already own
- Plain WAV and .mid files, plus a playable instrument

Why this one is worth having
More than a stereo delay
Bounce cross-feeds two lines running two note divisions, so repeats travel across the field instead of alternating sides. There is a real Dry/Wet mix and a duck from the dry vocal, a scope that draws the repeat train before you hear it, and reverb, saturation and compression after the delay in the same plugin.
One artist's chain, not a genre preset
Quadrature phase, bloom after width, the 220 Hz low cut, and the feedback ceiling are her settings. They stay design constants instead of becoming knobs that could lie.
You can hear it before you own it
The plugin runs in the browser on its own module page. No account, no installer, no demo timer. The product page is the demo.
Sounds that arrive already usable
The mini bank is drums and MIDI chosen for this effect, so the first thing you play is in tempo and in the right pocket.
Plain files, not a walled garden
The bank ships as a playable instrument and as WAV and .mid files. What you buy opens in whatever you already use.
The artist
Jazz Calls Home
Spanish-Colombian experimental pop artist and sound sculptor
Jazz Calls Home is the experimental pop project of Jazz Alvarado Segovia. Drawing on her background in film scoring and music production, she brings glitch-pop detail, electronic texture, and deeply personal writing into immersive songs.
Born in Bogotá and now based in Montreal, Jazz began with cello and youth orchestras before becoming a songwriter and sound sculptor. She has released music as Jazz Calls Home since 2020 and signed with Rexius Records in 2024.
How it came to be
Jazz had a crystal-clear vision for her ideal plugin: the enveloping vocal effect she rebuilt session after session, distilled into one instrument.
Sparklelizer turns that complex chain into an expressive stereo space where vocals bloom wide, move with the track, and still stay present at the centre.
Her chain never stopped at the delay, so the plugin does not either. A room, some saturation and a compressor sit after it: one amount each for the room and the saturation, and Threshold, Ratio and Makeup on the compressor. Jazz put the compressor last on purpose, in her words because it brings the delay feedback up in volume, if you want to hear more of that.
