Lexicon PSP 42

return of the legend!

Lexicon PSP42 is a high-quality digital stereo delay and phrase sampler plug-in based on the legendary Lexicon PCM42 processor famous for its unique concept and distinctive sound.

In version 2, the original vision of Lexicon PSP42 has been enhanced both in sonic accuracy and feature flexibility. In addition to the lush tape saturation algorithm and emulation of the variable sampling rate delay line that made the sound of the original PCM42 so unique, version 2 now adds even more precise modeling of the hardware’s audio path, in a manner that allows the user to quickly decide on how much of the original character should be used. In addition to the Legacy processing mode of the previous version, Lexicon PSP42 now offers three alternative modes:

  • Clean: a pristine signal path with no emulations

  • Lims: engages the original hardware’s two opto limiters, one at the input and one just before the A/D – the first affecting Dry and Wet signals, and the second affecting Wet and Feedback signals

  • Full: engages emulation not only of the limiters but also of the original A/D and D/A converters in the hardware PCM 42, whose non-linear behavior added a unique sonic twist.

Lexicon PSP42 v. 2 adds several new features unheard of on the original hardware, including up to 28800 ms of delay time, adjustable Hi Cut filter frequency, LFO tempo sync and waveform phase adjustment, adjustable input level sensitivity to simulate –10 dBV or +4dBu operation, options to invert the Envelope Controller signal or control it with a sidechain input and four Direction modes to simulate various forward and backward repeat options. It even has a Bypass button that leaves the input limiter in the signal path, providing a subtle, realistic coloration to “dry” signals. All of these new functions are presented on an easy-to-use Extensions panel under the plug-in’s standard controls.

Lexicon PSP42 excels at all types of delay-based effects, from tempo-locked feedback delay with filtering to modulated effects like flanging and chorus. The modulation section uses the PCM 42’s unusual trick of changing delay time by altering sampling rate to create everything from gentle animation and swing to unpredictable alien sound effects. Superior DSP algorithms allow for smooth operation with even the craziest settings, combining the plug-in’s infinite possibilities with unmatched sound quality.

PSP is the sole developer and manufacturer of the Lexicon PSP42. Functionality and sound of the Lexicon PSP42 have been approved by Lexicon. PSP is responsible for all customer support.

Lexicon PSP 42 is primarily intended for processing individual tracks within a mix. It delivers superior delay-based effects on vocals and all kinds of solo instruments, and now simulates vintage delays with its adjustable tape saturation, tape speed/direction, and high frequency filtering.

Tempo locking and a handy modulation section make Lexicon PSP 42 an essential tool for experimenting with drum loops and other rhythmic patterns. Its variable delay line sampling rate can easily create great-sounding lo-fi effects as well as out-of-this-world sounds.

When running at shorter delay times, the built-in pitch modulation and phase inversion controls turn Lexicon PSP 42 into a source of vibrant modulation effects such as flanger and doubler.

Last but not least, Lexicon PSP 42 can act as a simple phrase sampler, letting you capture a loop of audio and process it in real time without clicks, pops, or other artifacts.

In order to run Lexicon PSP 42 in 30-day trial mode or activate it, you don't need any hardware dongle but you need an iLok user ID which you can create for free at www.ilok.com, and you need to install the free iLok License Manager application.

You can activate the license in 3 separate locations, each of which can be either a computer or an iLok dongle (2nd generation or above). You can move these licenses at any time using PACE's iLok License Manager software.
