Physion

New Name, Same Great Effect

Physion (formerly known as Fission) is the first plug-in to use our ground-breaking Structural Effects technology - A new method for processing audio. It allows you to split a sound into its transient and tonal parts, independently manipulate them using Eventide's world-class effects and then fuse them back together. With the ability to add effects and dynamic controls to the transient and tonal sections, you can produce a wide range of effects, from the subtle to the extreme.

  • Physion/Fission plugin GUI Structural Effects Transient Tonal Separator

Features

  • Split audio into “Transient” and “Tonal” components
  • Radically re-shape a sound by soloing the Tonal and Transient channels. Tighten up drums by dropping the tonal section, or tune a guitar into an ambient sweep by losing the transients
  • Split, modify and reassemble any sound
  • Fine-tune the split using the four “Structural Split” controls.
  • Six Transient effects available: Delay, Tap Delay, Dynamics, Phaser, Reverb, Gate + EQ

Applications

Physion sound design plugin

Sound Design

Physion is a versatile tool for sound designers. Splitting and manipulating audio allows you to create and explore sounds never heard before. Remove transients from pianos or guitars to create bowed sounds,or go even further by adding extreme effects to the independent channels.

 Retune congas with Physion

Drum Tuning

Physion allows you to easily re-tune a drum without affecting the transient. Delay the cracking transient of a rimshot while leaving the tonal ring as-is. Solo out the transients to tighten up a sound and add some compression to tighten further.
Physion for vocals

Articulation

Physion’s structural split can be used to modify vocals in subtle or drastic ways. Emphasize or reduce sibilance, add or remove resonance, or turn robust vocals into whispers.

 Physion for transient design

Transient Shaping

Physion is not a traditional transient shaper - it’s a transient separator. It goes beyond what has been possible by allowing you to surgically tune the transient and tonal response independently.
Audio Restoration Picture

Audio Restoration

Remove unwanted tonal ring and hiss, or just reduce it with compression/expansion. Beef up the transients from old instrumental recordings to improve presence in a mix without squashing the life out of the tonal material.

Fission Screen
SOURCE TYPE
Selecting SOURCE TYPE sets the under-the-hood expert tunings that prime the analysis and decider for a natural sounding split of a given source.
FOCUS
Adjust the FOCUS contol to 'fine tune' the parsing of the sound based on contextual and musical desires. FOCUS forces the method to favor one stream over the other. Sliding FOCUS toward tonal will result in a more staccato transient stream. Sliding FOCUS toward transient will result heavier transient tails along with tonal auto-swell. Extreme settings will push the entire signal to either the transient or tonal stream. The FOCUS control can be used to make subtle modifications like de-essing, de-reverberating or reducing pick noise by adjusting transient and tonal gain.
TRANS DECAY
Turning up TRANSIENT DECAY preserves energy in the transient stream, further thickening up the transient tail as well as increasing the auto-swell on the tonal stream.
SMOOTHING
SMOOTHING controls the speed of the decision-making process, preventing it from making too fast a decision either way. This is useful for trimming out unwanted transient chirps or smoothing rough transitions.

Explore the Effects

Six Transient Effects

Fission Transient EQ

  • Delay - A standard Delay echo effect with Tempo Sync capability and low and high cut filtering.
  • Tap Delay - A multi-tap delay-line with Tempo Sync capability. Useful for rhythmic delays, wacky comb filtering, volume swells, or unique reverberant sounds.
  • Dynamics - A combined Compressor/Limiter and Expander/Gate (function is determined by Ratio control).
  • Phaser - A classic multi-stage allpass based Phaser effect, which can be controlled via LFO or Envelope.
  • Reverb - A room Reverb designed with high echo density, imparting a fast and smooth build-up of reflections. This pairs nicely with transient sounds to create a sense of space without obvious echo slap back.
  • Gate + EQ - A Gate followed by a 3-band overdrive-able EQ.

Seven Tonal Effects

Fission Tonal Delay

  • Compressor - A standard Compressor/Limiter.
  • Chorus - Multi-voiced chorus with randomized modulation
  • EQ - A 3-band overdrive-able EQ.
  • Delay - A standard Delay echo effect with Tempo Sync capability, modulation, and low and high cut filtering.
  • Reverb - A large space Reverb designed with lower echo density (compared to Transient Reverb) and targeted high modal density with little to no modulation to avoid a chorusing sound on the tails. This allows the tonal audio to breathe in the space, yet evolve into dense pad-like reverberant tails.
  • PitchShift - A 3-voice Pitch Shifter with +/- 1 octave shift per voice and an overall fine tuning control. Useful for retuning drums, creating harmonies, or micropitch chorusing/double-tracking all without transient slap back or smearing.
  • Tremolo - A standard Tremolo effect which is driven by an LFO in (optional) combination with the Envelope of the plug-in’s input.

Reviews

Controlling how sound sources enter and leave the picture is key to getting great mixes, and, as an example, I can imagine new ways to tailor the decay a and attack of a kick drum at several different frequencies.
Larry Crane
Tape Op
...with the new Fission [Physion] plug-in, Eventide continues its quest to push the boundaries of sonic manipulation...
MusicTech.net

It’s like no other effects processor on the market, and it offers enormous creative possibilities... Any source can be manipulated and tweaked in ways that were not possible before.
Mike Levine
Electronic Musician
Fission [Physion] is a monster. You can create delayed pick hits with phased undertones, reverbed plucks with dry-pitched tonal drones, slow bowed-sounding piano notes with tremolo wobble... and the list goes on and on.
Paul Vnuk Jr.
Recording Magazine
Fission’s [Physion] structural split functionality is an innovation not typically available in an effects plug-in. It rewards experimentation in more esoteric scenarios, but also works nicely for repairing audio.
Paul Williams
TabMuse.com
This next-level approach opens up a whole new universe of processing possibilities, from precise drum tuning, frequency shaping and dynamics sculpting through to cinematic sound design, esoteric weirdness and beyond.
Computer Music
MusicRadar
Fission [Physion] is the perfect tool to use when you are seeking to apply a more detailed approach to your engineering... It’s an idea that no other company to our knowledge has attempted, and Eventide has executed their idea resulting in the perfect plugin for this case.
Jimmy Byrne
All Things Gear
Apart from opening a new frontier in plug-ins, its strength is that it encourages an approach that blurs the line between practical and creative sound design applications.
Mark Smith
Resident Advisor
I had excellent results using Fission [Physion] for transient balancing on bass, and I was able to remedy a track in such a way that I’ve only been able to partially achieve elsewhere.
Dan Gluszak
SonicScoop
5 Stars. It’s so clever that it begs the question: why no one has done this before?... Fission [Physion] is a remarkable plug-in, capable of pulling out tricks that were otherwise very hard to achieve, heavily favouring creativity and experimentation
Diogo Borges
Gearslutz
This isn’t your run of the mill transient shaper, this is something very unique indeed... It’s a new way of affecting audio and I like that.
Dan Cooper
Pro Tools Expert
Despite its initial apparent similarity to traditional transient shapers, Eventide has come up with something very new and different with Fission [Physion] creative sound design and audio mangling.
Joe Albano
Ask.Audio
Eventide wants to change how you think about processing audio... So you could separate the pitched, resonant components of a tom and separate it from the hit, or take fret noise out of a guitar sound, or mangle new sounds entirely.
Peter Kirn
CDM
Eventide Fission [Physion] is a seriously great sounding plug-in that stimulates experimentation otherwise not possible. I highly recommend giving it a spin. And kudos to Eventide for really imaginative and creative plug-in development.
Eli Krantzberg
Logic Pro Expert
The separation of the incoming audio into transients and tonal parts of the signal, leading to parallel multi-effects, introduces a new level of sound design like no other plug-in can deliver.
