Lexicon PSP 42: Tape-Style Stereo Delay and Phrase Sampler by PSP Audioware

The plugin combines a tape saturation stage, based on the algorithm used in PSP's line of mastering processors, with a low-pass filter that models high-frequency absorption. Together these elements aim to give repeats the warmth and gradual darkening associated with vintage tape delays.

The delay line runs at a variable sampling rate. PSP Audioware notes that this makes the unit useful for low-fi effects, and that the chosen interpolation algorithm keeps those effects smooth. The developer also states that care was taken to avoid audible clicks or pops during operation.

A modulation section offers three sources, a sine, a square and an envelope detector, which can be mixed in any proportion. Delay time and pitch can be controlled continuously, and the plugin stays synchronized to the host tempo, including tempo changes.

Parameter filtering and on-the-fly cross-fades are included to keep changes smooth. MIDI and VST automation are supported, along with Logic Control support for hardware control. Short delay times with pitch modulation can produce flanger and doubler-style effects. The developer describes the processor as suited to individual tracks in a mix, such as solo instruments, vocals and drum loops.
