World's Most Musical Reverb

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 providing advanced control over tempering for a broader range of scenarios for both studio creation and live performance.

Target Select (Early, Late, All) 

Target the moment, choose when tempering happens; at the reverb onset (Early), during the reverb tail (Late), or both (All).

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. With Transpose, shifting everything up or down a couple of semitones is simple.

Sequencer

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

MIDI Mode

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

Unique Modal Controls

The Mix, Decay, and Size controls provide familiar tools for fine-tuning space. Temperance Pro expands on these for the first time with modal features for shaping the ambiance in unique ways - even with the Temper knob set to noon.

Position

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

Density

Reduce density to remove modes creating a progressively more fragmented lo-fi sound. At 100%, all modes in the space are active.

Offset

Offsets the center frequencies of all the modes by up to ±500Hz, independent of temper settings. Reposition the entire space up or down in ways not possible with traditional reverbs.

World Class Modal Spaces

Temperance Pro includes 29 spaces that sound exceptional on their own. Intimate rooms, grand halls, lush mechanical reverbs, and for the first time, experimental synthetic spaces. Algorithmic and convolution reverbs have been faithfully transformed into the modal domain using our patented machine learning technology.

The collection includes authentic recreations of legendary spaces, including a handful designed by acoustics pioneer Ralph Kessler, alongside Eventide’s original creations built specifically to showcase the new modal reverb technology. 

The Science of Modal Reverb

Imagine a room filled with thousands of tuning forks, each one a different size and tuned to a specific frequency across the entire audio range. The largest fork handles the deep 20Hz rumbles, while the tiniest one rings at 20,000Hz.

Temperance Pro gives you complete control over the loudness and decay rate of each tuning fork, modeling any reverberant space as a collection of thousands of independent resonators, each one adjustable in real-time. 

The modal approach breaks free from the limitations of traditional reverbs, letting you create spaces that feel musically intentional rather than incidental. Temperance Pro responds to the language of music itself, delivering studio-ready ambiance with uncompromising control and character.
