Physion Mk II: Multi-Effect Plugin by Eventide

Physion Mk II divides incoming audio into two streams. The transient stream is for attacks and percussive detail, and the tonal stream is for sustained and harmonic content. Each stream gets its own effect chain and output level control, so you can add reverb to a drum room without washing out the hit, or pitch-shift a vocal's body while leaving its consonants intact.

The underlying split can be adjusted directly for fine-tuning. Eventide describes the new filters as taken from SplitEQ, and the scrolling waveform display with a resizable interface keeps the controls visible while you work.

The transient side offers delay, tap delay, dynamics, phaser, reverb, gate with EQ, and reverse delay. The tonal side offers delay, dynamics, pitch, chorus, reverb, tremolo, EQ, and reverse delay. The new polyphonic pitch shifting algorithm is based on Spectral Instantaneous Frequency Tracking, and the reverse delays include gating, ping-pong, and crystals modes.

The factory library of over 500 presets is organized into categories ranging from subtle color to deep transformation, which gives you a starting point before you build your own settings. A/B comparison and undo/redo help when you are exploring options.
