accuracy than analog oscillators.
A system of sound recording where an analog sound is converted into digital
Digital
Sampling information and stored in computer memory or on a disk. In the Mirage, sampled
sounds are given pitch control via the keyboard permitting any recorded sound
to be played back as music.
Digital A sequencer that records and plays back notes based on information about key
strikes, key velocity, and pitch and mod wheel positions rather than recording

sound output.
Envelope A term used to describe the amplitude contour or filter cutoff frequency contour
as a function of time. Acoustic sounds have natural envelopes as vibrations
attenuate over time. Electronic instruments have envelope generators to create
this effect.
The symbol for cutoff frequency, or that frequency at which the sound begins to

be attenuated.
Fine Tune A control used to make small adjustment in pitch. The Mirage's fine tune
parameter permits pitch changes as small as 1/20 semitone.
A Mirage diskette that contains a framework for sound information, but no

Diskette actual information. Used to store sampled sounds, programs and sequences.
Hexadecimal A form of mathematical notation called "base 16". As used in the Mirage
display, it permits the display of all 256 "pages" of wavetable storage using only
two digits in the display. Numbers 0 through 9 are represented by themselves;
the numbers 10 through 15 are represented by "A" through "F".
A signal entering an instrument. Also the point at which it enters.
Input
Literally, the place where any two things come together. In musicianspeak it is

commonly understood to be the linking of two pieces of electronic equipment
together.
Keyboard A controller used to give pitch and dynamic control of a musical instrument to
the player.
Assigning a different value to a parameter based on which key of the keyboard is

Tracking depressed. For example, the cutoff frequency of a filter can move up as higher
keys are played.
Low frequency oscillator. These oscillators operate in the sub-audio range and
LFO
control the frequency of effects such as vibrato.
Line Level An audio signal whose strength is at least 800mV.
Load In the Mirage, a term used to describe the transfer of data from diskette to the
internal memory.
A term used to describe the connecting of the end of a signal or sequence to the
Loop
beginning point of some intermediate point along its duration. As it applies to a
sequencer, it means that the sequence will start over immediately after it
finishes. As it applies to sampling, it means creating a continuous sound by
connecting two points in the wavesample.
A filter that attenuates the frequencies above the cutoff frequency.
