Ensoniq ASR-X Pro
A professional sampler and music production workstation from Ensoniq, billed as a "Resampling Production Studio," with flexible sample rate selection and expandable memory.
Overview
The Ensoniq ASR-X Pro is a sampler and music production workstation. Official promotional material called it a "Resampling Production Studio," because it can resample audio internally. The case is pressed steel and measures 17" wide, 13" deep and 4" high. It weighs 12.5 lbs (5.67 kg) without packaging. It was released between 1997 and 1999, and some sources give 1998.

Design
The ASR-X Pro resamples within the unit, so you can process audio and sample it again. Sample memory expands with 72-pin SIMMs, and the two sockets have different size requirements. The operating system and settings live in Flash memory, so the unit doesn't depend on battery-backed RAM to keep its configuration.
Context
The ASR-X Pro came out between 1997 and 1999, approximately 18 months after the original ASR-X. Ensoniq was busy at the time. The ZR-76, Fizmo and PARIS digital audio workstation are all listed for 1998 too. From the name and the feature set, it looks like an enhanced ASR-X aimed at advanced sampling and production work.
