The Ensoniq ASR-10 (Advanced Sampling Recorder) was a sampling keyboard manufactured between 1992 and 1994. It was a follow up product to the very popular Ensoniq EPS and Ensoniq EPS 16+ performance samplers. The ASR-10 was a true performance orientated sampling workstation, and did not require a computer or additional equipment in order to create a complete song. It included a powerful and flexible effects unit, polyphonic aftertouch, an advanced MIDI sequencer, load-while-playing abilities, and a powerful multi-layered synthesis engine. Different layers could be triggered by any number of modulation sources, including velocity, polyphonic aftertouch, or combinations of the two layer keys on the left hand side of the keyboard. The ASR-X followed as a single tabletop unit with professional sampler specifications, and easy yet professional sample editing features.
Ensoniq sound engineers produced a collection of Compact Discs “CDR Series” consisting of the factory content used to create the EPS (Ensoniq Performance Sampler), Ensoniq TS-10, and ASR sample libraries. 1,000’s of floppy discs were transferred to CD’s allowing the newer samplers to load sounds directly from CD-Rom drives. This was a large step forward for samplers giving musican’s quick and easy access to large collections of sounds.
