Pro Tools and Digital Performer) and include basic effects plug-ins.
Plug-ins are computer-based digital effects and signal processing virtual
units that perform the same functions as their hardware counterparts.
Effects incorporated with most programs are reverbs, echoes, equalizers,
gates, and compressors. As with hardware units, there are many varia-
tions and choices of plug-ins. They all sound different and offer dissimilar
features. Since purchasing third-party effects can be costly, before pur-
chasing it is advisable to listen to the demo CDs provided by most manu-
facturers. Many manufacturers also offer demonstration downloads from
their websites as a marketing tool. Some of the plug-ins automatically
erase after a predetermined time period.
Hardware-based digital recorders do not require tape.Much the same
as computer-based recorders, these units provide nondestructive editing
features as well as the same basic functions offered with computer MIDI
audio programs. To a composer/arranger, the advantages of computer-
based digital technology unquestionably have no competition. Digital
technology has transformed the recording industry.
One of the problems with computer-based digital audio is that it
requires sizable hard-disk memory for storage as well as additional proc-
essing power to operate peripheral music software. Digital plug-ins also
require supplementary processing power. Insufficient processing power is
frustrating and hinders programmers from completing their creative
visions. Consider the following advice:
- Purchase the fastest computer with the most RAM that your budget
allows. - Save digital audio on a separate hard drive. Do not save audio on
the same hard drive that contains the computer’s operating system.
Many problems can occur because of this practice. - Burn a CD or DVD of your files as a safety measure and for future
reference. Memory is a valuable commodity, and even large storage
drives eventually fill up. It is wise to save your files on several out-
board hard drives.
Samplers
A sampler records audio, converts it to digital audio (stored in RAM), and
plays back through the use of a music-sequencing program. Notes gener-
ated from a keyboard controller can trigger the sampled sounds. Many
sampling CDs and CD-ROMs, containing virtually any sounds composers
require (e.g., orchestral instruments, drum loops [grooves], sound effects,
and so on), are sold in retail outlets or can be downloaded.
Samplers are hardware based and computer based. The sounds can be
edited, which helps to achieve a wide variety of sound manipulation. Fil-
ters, velocity, time compression (changing tempo without changing the
