Ensoniq ASR-X (1997–1999)
A 16-bit stereo sampler and workstation with built-in synthesis, effects, and resampling capabilities.
Overview
The Ensoniq ASR-X was produced from 1997 to 1999. It is a pro-spec 16-bit stereo sampler/resampler built for production use. It works as a full workstation: sampling, sequencing, a built-in MR synthesizer, multi-effects, and 18 dB resonant filters. An enhanced version, the ASR-X Pro, came out as an update and was marketed as a "Resampling Production Studio." Storage is a 3.5-inch floppy disk drive, and the front-panel knobs are central to how the machine operates. It was originally priced at $1,000.

Design
Two central front-panel knobs handle most operations on the ASR-X. The documentation is split into multiple volumes, including the "Producers' Mix" User's Guide and the ASR-X Pro Reference Manual. The X-8 8 Output Expander adds expansion. In the box you get the User's Guide, Reference Manual, FDX-100 sound and demo floppy disk, hex wrench, and AC power cable. There is also an addendum for the v2.00 operating system.
Context
The ASR-X Pro is an enhanced version of the ASR-X, with updated capabilities for sampling, synthesis, and sequencing. It was positioned as a professional production tool, and its documentation and name point to a focus on resampling workflows.
Market
Used units have been listed at $800, down from the original $1,000 price. The 3.5-inch floppy disk drive is available as a replacement part for $54. Users are still looking for replacement encoders for the ASR-X Pro.
