The Orban 290RX Adaptive Enhancement Processor was an interesting product that was on one hand a sound restoration device, and on the other a noise reduction system.
The Roland SDE-330 digital delay was released at the same time as the SRV-330 and offers just as spectacular performance as it's sibling.

Roland had by now made a number of digital delays, and the SDE-330 showed they had nailed the concept. The SDE-330 is a brilliant digital delay with a few tricks up it's sleeve to make it stand out.
High Quality Effects
The effects produced by this unit can rival those of much costlier devices (often found in professional studios). This is because the Roland SDE-330 uses 16-bit, 44.1kHz digital processing, and was designed as a result of painstaking efforts directed at redefining and redeveloping all the essential features that a professional-quality, dedicated delay should have.
The Roland SDE-330 provides newly developed algorithms which can deliver effects that are quite revolutionary such as a delay which results in sounds that seem to fly around the listener. New effects such as these can be provided thanks to the technological expertise accumulated through Roland’s development of the RSS (Roland Sound Space) system.
Full Stereo Support
With every stereo algorithm, the internal processing of the left and right channels in the Roland SDE-330 is done independently. This assures that every detail of spatial localisation contained in the input signals is retained even after effects have been applied.
Provides a wide variation of algorithms that are ready for almost any situation where you may wish to use delay.
Real-Time Parameter Control
The effects you obtain can easily and conveniently be altered while a performance takes place. Either pedals, or MIDI messages can be used to control specified parameters.

Beautiful sound from this truly ‘special effects’ delay. Rock-solid build quality and possibly the best user interface ever on any unit with page buttons and scrolling display to show you all the parameters in a left to right motion. Makes a lot more sense than going deep through menus. The 3D ping pong effects are unlike any other unit out there and the degree of control over every aspect of the sound makes it a very fun unit.
Using the RSS technology its possible to change the position front to back behind your head and below and above your head for some fantastic and dramatic effects. The wild doppler and chorus effects are stunning and as a vocal fattener it’s on par with the Eventide Harmonizer. Had mine since 1993 and I still use it in every production today.
