PSP 285 is a powerful semi-modular delay plugin designed to deliver a broad spectrum of delay effects, ranging from simple slapbacks and echoes to complex rhythmic patterns. It builds on the legacy of PSP's acclaimed PSP 84/85, offering high-quality audio performance that caters to both traditional and experimental sound design. Users can explore everything from authentic magnetic tape delay emulations to innovative pitch-shifting and resonant filtering effects, all within a single, flexible platform.

The plugin features a semi-modular architecture that supports up to 10 seconds of delay per channel, with continuous control over delay times and pre-delay settings. It allows for cross-channel feedback, independent channel adjustments, and channel linking, enabling detailed stereo or mid-side processing. Additional features include delay gating for precise echo control, wet signal ducking to maintain clarity, and a modulation section with tempo-synced LFOs and envelope followers that can be blended to shape sound dynamics creatively.

PSP 285 includes a wide variety of filter types with adjustable cutoff and resonance, along with flexible routing options and a drive algorithm offering hard and soft saturation modes. Its reverb module features multiple algorithms such as springs, plates, and reverse reverbs, which can be positioned freely within the signal chain. With support for sample rates up to 384 kHz and a high-quality 64-bit floating-point signal path, PSP 285 ensures pristine audio fidelity and smooth, click-free operation, making it ideal for professionals seeking comprehensive delay and spatial effects.
