The Lexicon PCM 90 gives you Lexicon’s renowned high-end reverb effects with a powerful new interface that provides easy access to superbly crafted presets as well as a wealth of programming capabilities for the sound designer.

The Lexicon PCM 90 contains a built-in library of 250 reverb effects that simulate realistic halls, rooms and plates, and let you create completely natural, or other-worldly spaces. The presets are organized into 5 Banks of 50, and are functionally grouped for different applications. 

The Lexicon PCM 90 uses 5 stereo algorithms to create different types of reverb effects. Each algorithm includes an uncompromised stereo reverb effect with selected “tools” for ambience, post-processing, compression/expansion, as well as modulation and patching parameters which are common to each algorithm.

A unique Patching and Modulation system provides unprecedented control over your effects, with a versatile set of internal modulators: two LFOs, AR Envelope, Envelope Follower, Latch and Time Switches, MIDI Delay and Sample and Hold.

These allow you to create modulation sweeps which move in time with music, or animated effects. You can create as many as 10 patches per effect, each with as many as 8 pivot points. You can patch multiple parameters to a single controller, or patch multiple sources to a single destination.
