PSP 84

The PSP 84 is a remarkable processor that delivers a wide array of delay-based effects, making it an excellent addition to any audio mixer setup. With two independent delay lines and variable sampling rate, the resulting audio simulations are incredibly realistic. The precise tape saturation algorithm with adjustable gain is particularly impressive, which convincingly simulates tape delay, complete with all the fascinating effects resulting from tape speed instability.

In addition, this processor features a filtration section, comprising of three 2nd order switchable resonant filter types, which can be used to process input, feedback or wet signal. The adjustable slope of the filter ranges from a gentle curve, ideal for simulating high frequency absorption typical for tape delay, to an extremely steep curve with a high cutoff frequency peak, which easily provides all the wild wah-wah and resonance effects.

The PSP 84 goes even further, allowing delay line sampling rate and filter cutoff to be modulated by any of the 5 LFO waveforms. These LFOs are automatically synchronized to the sequencer tempo or envelope follower, adding a new layer of depth and dimension to your audio output. Furthermore, the system ensures that modulation can be fine-tuned with adjustable sensitivity and attack/release.

Ultimately, this remarkable device is all-encompassing. It even features a fully functional reverb unit, with simplified settings carefully tuned to exactly reproduce the sound of classic spring and plate reverberators. The PSP 84 is an excellent software choice for anyone looking to incorporate delay-based effects with impressive precision and versatility.
