Reverb Algorithm and Sound Character

The core of the EMT® 250 Classic Electronic Reverb is its reverb algorithm. Universal Audio states that the plugin is an emulation of the EMT 250 that uses the same algorithm as the original hardware, rather than an approximation of it.

The developer ties the sound to recordings it describes as having used the EMT 250, including Prince's Purple Rain and Red Hot Chili Peppers' Stadium Arcadium. Those references are the developer's and describe the hardware's history, not a guarantee of how the plugin will sound in your mix.

Modulation Effects and Workflow

Beyond reverb, the plugin provides six modulation effects: delay, phasing, chorus, echo and two additional space-style effects. Universal Audio describes these as the ’70s-style tones the original unit was known for, useful for adding vintage ambience to individual tracks or to a full mix.

Because the reverb and effects sit in one plugin, you can shape a send or insert chain without loading separate processors for each effect type.
