5. Parts and Voices
(1) Relationship Between The Number of Voices and Parts
There are 24 tone-generating circuits, called oscillators or voices, in the CM-300.
That
means 24 notes are available at any one time.
Jut since there are tones that use two voices, the actual number of notes that you can play
at any one time is going to be less than that.
Which means, for tones that require exactly
two voices, you can play a maximum of 12 notes.
And when it comes to rhythm parts, the
number of voices depends on what rhythm sounds are being played at any one instant, so
the total number of voices used will vary widely from one moment
to the next.
It is the total number of voices in all parts which is important, so you could conceivably use
all the available voices in just one part if you wanted.
That means one part could use up
to 24 voices.
Check with the Tone Table (page 23) or Drum Set Table (page 28) to find
out exactly how many voices are used by each tone.
(2) What Happens When You Try To Play Too Many Notes
If you try to play more than 24 voices, some parts are going to lose their voice; and if these
are important
parts like the melody, things are going to sound funny.
To prevent the
occurrence of such a situation, the CM-300
provides the Part Sounding Priority and Voice
Reserve functions.
@ Assign A Higher Priority To The Most Important Parts
-Part Sounding Priority
If you try to play more than 24 GS voices at once, the new notes will be played by taking
away voices from notes that are already playing the ones which are lowest on the GS
Format's
Part Sounding Priority numerical ranking system.
So when writing a song, give some thought to what the most important parts are.

'The Voice Reserve function guarantees each part a certain number of voices in advance.
For
example.

of 6, meaning
that, even
if the
24.voice limit is exceeded, Part
10 is assured of getting 6 of the remaining voices.

other words, if Part
10 uses 6 voices or less, there is no way that voices can be
"stolen"
from it. regardless of how Part Sounding Priority is set.
