INSTRUMENT VOICES AND POLYPHONY
Instrument voices are those Preset, GM, Internal, Song and (optional) External voices
assigned to tracks in the tone generator mixer. The number of notes you can play simulta-
neously with an Instrument voice either from the keyboard or from the sequencer is a
maximum of 32, but is determined practically by the number of elements used in a voice,
as well as the number of voices used in a sequence. The more elements that make up a
voice, the fewer number of keys that can be played on the keyboard, or generated by the
tone generator from the sequencer.
VOICE BANKS
The W5/W7 has a total of 10 separate
voice banks
. Eight of these are provided as
standard features, while two of them are available as optional ROM memories that you can
purchase separately and plug into the W5/W7 s logic board via a special access located on
the bottom of the instrument.
The various voice banks are organized according to the type of instrument sounds that
are in them i.e., by normal voices (voices with pitched sounds) or drum voices (voices
with assorted percussion sounds). Whether the voice bank is a normal or a drum voice
bank is indicated by a one- or two-letter abbreviation code, respectively, which appears
immediately to the left of the voice number. Following is a list of the various voice banks,
along with abbreviation codes and descriptions:
NORMAL VOICES
(G) GM VOICE
128 ROM sounds preset according to the General MIDI standard, which cannot
be overwritten.
(P) PRESET VOICE
128 ROM sounds preset at the factory, which cannot be overwritten.
(I) INTERNAL VOICE
128 RAM user memory locations which have voices stored in them when shipped
from the factory, but can be overwritten when storing your own original normal
voices, and will be retained in memory even when the power is turned off.
(S) SONG VOICE
128 RAM user memory locations for storing GM, Preset or Internal voices used in
a particular song or multi. Song voice banks each holding 128 normal voices for
each song can be saved to and loaded from floppy disks via the disk drive. Song
voices will not be retained in memory when the power is turned off.
(E) EXTERNAL VOICE
Additional ROM voices available as an option. (NOTE: The E will not display
unless the optional Expansion Wave/Voice Board memory upgrade package is
installed.)
