A sampler instrument built from rare and expensive vintage synthesizers — their character, captured sample by sample, on a living oscilloscope.
Phosphor is built to be played, not just browsed. Short clips of me using it like any other instrument — hands on the parameters, no edits, no external processing.
Everything you hear is Phosphor alone. Every parameter is MIDI-mapped to the keyboard — filter, envelopes, effects, all tweaked live while playing.
The kind of sounds you get out of Phosphor — recorded straight from the plugin, no processing.
Every page, every control, every trick — start to finish.
Play a chord — the tube answers. Everything you need for a quick shape, nothing else.
A full sample editor on the tube. Zoom into a waveform, shorten it to its sweet spot, loop it into an endless pad — or flip a 50-year-old machine backwards and find textures nobody has heard.
Transform your sound with the effects that matter — easy to use, quick results, everything saved with the preset.
Two browsers in one page. Work through finished presets by category, or skip presets entirely and load raw samples straight from the library — then save what you built.
The instrument adapts to your screen and your taste — and tells you exactly what the engine is doing while you play.
Every knob is MIDI mappable for flexible control. Grab a MIDI controller, turn a knob, and watch the exact same knob move on the tube — in real time.
The monitor isn't just a frame. Click the grey power switch and the tube collapses to a line — LED off, notes cut, the plugin bypassed until you click it again. Click the flap under the screen and it folds down onto three knobs that were always there.
The Yamaha CS-80 alone costs more than a car. Every sample in Phosphor was captured from the original hardware — sampled over the years in synth studios, private collections, exhibitions and on my own gear, then trimmed, tuned and processed by hand. No emulation, no modeling.
"If you know Kleemann's demos on Instagram, you know that sound — warm, vintage, unmistakably eighties. Phosphor captures it perfectly. The presets are rich with authentic analog character, not a generic 'retro' filter but the real texture Kleemann is known for. What stands out beyond the sound is the attention to detail: a clean, thoughtful UI plus a few hidden surprises tucked into the plugin that reward curious users. If you don't own Kleemann's actual synth collection (most of us don't), Phosphor is the perfect shortcut to that sound. Highly recommended."
"I really like the feeling of Phosphor! The GUI with its retro touch really feels like it is made with love. Its presets & samples are well curated and contain a fantastic sounding variety of sophisticated oldschool synths. It also offers great tools for editing its samples and for sound design. The little easter eggs add to the already cool touch Phosphor has. All in all great work from a great creative mind. Do not miss out on Phosphor!"
"What stood out to me was how easy it was to create sounds with real emotional depth. The 'Hans Zimmer' pad was my personal highlight. I had a lot of fun exploring the sounds, especially playing around with the delay section."
"I definitely love Phosphor. I made a few beats with it. I'll send you one when it's finished."
"The sounds are phenomenal. They have this incredible vintage vibe that works perfectly for old-school electronic music, but at the same time, they sound totally relevant and fresh for modern, new-school production. It's extremely versatile. Every single patch feels highly authentic and beautifully, crisply recorded. It is such an inspiring, unique, and unusual plugin to work with, and I'm honestly amazed by how lightweight it is. It doesn't weigh much at all, yet the sonic weight is massive. This is a top-tier, exceptionally well-done piece of work. For anyone who loves fat analog warmth and gritty retro textures, this plugin is an absolute must-have. You nailed it!"
Somewhere in Phosphor, the oscilloscope stops drawing your chords and boots a menu of six playable games instead. No hints — you'll know it when you hit it.
