Temperance Pro speaks the language of music, operating on the 12-note chromatic scale to determine which notes bloom or fade within space. Its expanded control set shapes musical texture, directs movement, and unlocks 29 world-class spaces built entirely on modal technology.

Shape the Musical Texture

Temper and Range controls dial in the musicality of the reverb, adjusting the amount of emphasis or de-emphasis applied to the selected notes, and choosing which octaves are tempered. Target and Note Width expand on these settings for a broad range of applications live or in the studio.

Note Width: Determine how broadly each note spreads within the modal field. Lower values produce purer musical results. Higher settings disperse the note energy, for richer chorused tones. The default 50% provides a balance of focus and dispersal.

Direct the Musical Movement

Determine which notes drive the motion using the Note Selection panel, featuring Manual, Sequencer, and MIDI modes.

Manual: Build custom note selections with one click using a note-roll style input. Use the Choose Scale dropdown to instantly highlight chords, scales, modes, or even intervals.

Sequencer: Sequence mode turns reverb into a compositionaltool. Program note changes to follow chord progressions,scales, or intervals for dynamic musical results.

MIDI Mode: Take command with MIDI mode. Connect a MIDIdevice to select notes in real-time, offering an immediate,tactile way to work with Temperance Pro.

Unique Modal Controls

fine-tuning space. Temperance Pro expands on these for thefirst time with modal features for shaping the ambiance inunique ways—even with the Temper knob set to noon.

Position: Adjust the balance between early and late reflectionsto change the perceived listening distance from the source.Position can work with the Target selection to further highlightor de-emphasize the tempering.

Density: At 100%, all modes in the space are active. Reducedensity to remove modes creating a progressively morefragmented or lo-fi sound.

to ±500Hz, independent of temper settings. Reposition theentire space up or down in ways not possible with traditionalreverbs.

World-Class Modal Spaces

Temperance Pro includes 29 spaces that sound exceptionalon their own. Intimate rooms, grand halls, lush mechanicalreverbs, and for the first time, experimental syntheticspaces. Algorithmic and convolution reverbs have beenfaithfully transformed into the modal domain using ourpatented machine learning technology.

The collection includes authentic recreations of legendaryspaces, including a handful designed by acoustics pioneerRalph Kesseler, alongside Eventide’s original creations builtspecifically to showcase the new modal reverb technology.

The Science of Modal Reverb

Imagine a room filled with thousands of tuning forks, eachone a different size and tuned to a specific frequency acrossthe entire audio range. The largest fork handles the deep20Hz rumbles, while the tiniest one rings at 20,000Hz.Temperance Pro gives you complete control over theloudness and decay rate of each tuning fork, modelingany reverberant space as a collection of thousands ofindependent resonators, each one adjustable in real-time.

The modal approach breaks free from the limitations oftraditional reverbs, letting you create spaces that feelmusically intentional rather than incidental.

Temperance Pro responds to the language of music itself,delivering studio-ready ambiance with uncompromisingcontrol and character.

Two Intuitive Meters to Dial In Tempering
