the ratio number, the sharper the attenuation. The Mirage filters have a rolloff
slope of 24dB per octave.
Sample In the Mirage memory, each location is referred to as a sample, 256 samples
make up one Page.
The number of times per second that a digital record is made of an audio wave
Sampling
Rate form. The Mirage's default sample rate is 30,000 samples per second, though
that can be varied.
The process of transferring information from the internal memory of the Mirage

to a Formatted Diskette for permanent storage. The opposite of loading.
Page The Mirage memory has 64K memory locations divided into 256 Pages of 256
SAMPLES each. The beginning and ending points of each page are called
BOUNDARIES.
Sequence A set of keystroke commands stored in a sequencer.
Sequence A function of a sequencer where the recorded sequence is played over and over
until instructed to stop.
Loop
In the Mirage, a sound is defined as a WAVETABLE (comprised of up to 8
Sound
WAVESAMPLES) plus a PROGRAM (the collection of all the program
parameter values).
Ensoniq makes available preprogrammed sampled sounds on mini-diskettes.
Sound
Diskettes Each of these Sound Diskettes contains three distinct sampled sounds, with each
sound having four programs.
The Mirage features a split keyboard. The keyboard is divided into two sections
Split
Keyboard (usually, 31 keys lower, 30 keys upper). Different sounds or different programs
of the same sound can be loaded into each keyboard half.
Sustain The amplitude or filter level held from the end of the decay slope to key release.
Sync Connecting two or more units together so that clock pulses permit them to play
together in a synchronized fashion. The most common sync connections involve
sequencers and drum machines connected to keyboards.
Value Rather than have knobs, sliders and switches, the Mirage uses a system of
parameters and values to change and modify sounds. Expressed in numbers
(either decimal or hexadecimal), values represent amplitudes, frequencies,
balances and other conditions, depending on the parameter selected.
A system of sensors that can determine how hard and fast a key is played. This

Sensitivity information can be applied to control amplitude, filter frequency, envelope
functions and oscillator balance.

voices with two oscillators for each voice.
