Mirage DSK-8 Digital Sampling Keyboard

   (0 reviews)

The Mirage DSK represents a continuation of Ensoniq's commitment to providing its customers with low-cost, high-quality musical instruments. Thanks to a series of design improvements and more efficient production techniques, it is possible to offer an instrument with the same fine sound quality and virtually all the features of the original Mirage at a substantially reduced price. Plus, the Mirage DSK features the added enhancement of stereo circuitry.

All the sounds ever developed for the Mirage will play on the Mirage DSK, including the popular Ensoniq Sound Diskette Library, which covers the full range of musical instruments and other effects. See your Ensoniq dealer for details about the Sound Library.

The Mirage is an eight-voice polyphonic digital sampling keyboard instrument - in many ways similar to and in just as many ways different from a synthesizer. The Mirage allows you to personally program sounds like many synthesizers and also features an on-board sequencer. But, in addition, the Mirage will permit you to sample just about any sound you hear and create music with it.

It's best described as a computer specially designed to reproduce and process sound. Like all computers, it is a system consisting of two main parts--hardware and software. And here's where it differs most from synthesizers.


The hardware of the Mirage is everything that comes in the box with the exception of the on the mini-diskettes. The hardware itself cannot make any sound. It's an engine without fuel. What the hardware can do is reproduce process and modify the sound information included on the diskettes.


The information contained on the mini-diskettes is called software; this information consists of all the data necessary for the Mirage hardware to reproduce a sound. When this information is transferred, or loaded, into the memory of the Mirage, the hardware is ready to reproduce that sound or modify it in a nearly unlimited number of ways.

You, the user, can create your own software by taking sounds you record with the Mirage hardware and transferring that information onto a specially formatted Mirage diskette for future use. This process is called saving. Because all of the crucial sound information is included as software, your Mirage will never be obsolete. An ever-growing library of sounds is available from Ensoniq that will keep your Mirage fresh and new for years to come.

Digital Sampling

As it applies to music, digital sampling is a computer term that basically means "recording," In concept, it's very similar to tape recording--an electronic representation of a sound, or audio signal, is stored in some location where it can be read and changed back into a sound at some future time.

Tape recording uses audio tape to store the audio signal. Digital sampling uses sophisticated digital circuitry (and eventually, computer diskettes) to store the signal. In digital sampling, the signal is stored as bits of computer information. While in this digital form, the signal can be modified in many ways, without deteriorating the audio quality and without the mechanical limitations of tape recording.
