The general idea of the Lexicon PSP 42 inspired us to design it’s big brother the PSP 84 plug-in (VST and RTAS for Windows; VST and RTAS for Mac OS classic and AudioUnit, VST, RTAS for Mac OSX Universal Binary).
PSP 84 is a high-quality processor, capable of producing a wide variety of delay-based effects. Two independent delay lines operating with variable sampling rate and precise tape saturation algorithm with adjustable gain, allow for convincingly sounding simulation of tape delay, including all the exciting effects resulting from tape speed instability. A filtration section consisting of three 2nd order switchable resonant filter types can be used to process input, feedback or wet signal. The adjustable slope of the filter ranges from a gentle curve, which is useful for simulating high frequency absorption typical for tape delay and wet signal equalization to an extremely steep curve with a high cutoff frequency peak, making all the wild wah-wah and resonance effects easily available. Delay line sampling rate and filter cutoff can be modulated by any of the 5 LFO waveforms that are automatically synchronized to the sequencer tempo or envelope follower with adjustable sensitivity and attack/release. Moreover, the PSP 84 contains the fully functional reverb unit, with simplified settings carefully tuned to exactly reproduce the sound of classic spring and plate reverberators.
