PSP 285

The ultimate creative semi-modular delay machine!

PSP 285 is based on our legendary PSP 84 and PSP 85* delay plug-ins. It’s our latest exploration of the endless possibilities offered by variable sample rate delay lines. It can produce an extremely wide variety of delay-based effects – from simple slapbacks and echoes to complex rhythmic patterns, from faithful magnetic tape delay simulations to twisted out-of-this-world pitch-shifting and resonant filtering effects – all at world-class audio quality.

NOTE: Because of its many new features, PSP 285 is not backward compatible with PSP 85, which will no longer be developed further. PSP 285 will not replace PSP 85 when installed, but we recommend that you use PSP 285 in your new and future projects.

Current users of PSP 85 can crossgrade to PSP 285 for just $28.50.

WOW! And here I thought I knew the 85 delay already. The 285 feels like a Deluxe version. Amazing work. The layout is more user-friendly (says this user) and it pushes me to want to experiment more. Included with the new look is a variety of sound and tone available that I require in a great delay. The best tools can cover every color, flavor and mood, and the 285 excels in all of those areas. This would make it a ‘must buy’ for any engineer today, but that’s before we even talk about the M/S button. Another Wow. What a great option. You guys really covered everything in this one. Thank you!

In order to run PSP 285 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, 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.
