PSR-8000 Waves & Waveforms
The terms "wave" and "waveform" have distinct meanings in PSR-8000 sampling terminology, as follows:
WAVE
A "wave" is the raw audio data created whenever you sample
a new sound or import a WAV or AIFF format wave file. The
PSR-8000 WAVE EDIT mode includes functions which allow
you to edit this basic data: e.g. resampling to change the
sampling frequency, trimming and looping, normalization for
maximum level and minimum noise, etc.
WAVEFORM
All PSR-8000 waves are contained in a "waveform", which
is basically a set of parameters which define the keyboard range
over which the wave or waves it contains will play. A waveform
can contain one or more waves, and waves can be shared by
more than one waveform. Waves in a waveform can be assigned
to different ranges of the keyboard, but they cannot be layered
(i.e. they will not sound simultaneously when a single key is
played). The PSR-8000 WAVEFORM EDIT mode lets you add
or delete waves from a waveform, and assign the waves to
different keyboard ranges.
• When you sample a new sound or import a WAV or AIFF format wave,
a new waveform which contains the new sampled or imported wave is
automatically created. The PSR-8000 saves your edited data as a
waveform file.
WAVEFORMS & VOICES
Waveforms created by the PSR-8000 SAMPLING feature
can be used in voices in two different ways:

The PSR-8000 SAMPLING feature lets you "sample" sounds via a microphone or
line source which can be saved as "waves" within "waveforms" to be used in
original custom voices (see "PSR-8000 Waves & Waveforms", below). The SAM-
PLING mode also includes a range of wave and waveform editing features which
can be used to "fine tune" your samples for optimum sound.
During use sampled sounds are kept in the internal wave RAM memory. The
PSR-8000 comes with a 1-megabyte wave memory which can be expanded up
to a maximum of 33 megabytes by installing optional SIMM memory modules —
see page 152 for details. Sampled waveforms can be saved to floppy or hard
disk. Wave files in standard WAV or AIFF format produced using other equipment
can also be used by the PSR-8000.
• The supplied audio CD includes sound sources for sampling.
• No MIDI or TO HOST transmission or reception occurs in the SAMPLING mode.
