The PR-300S's Multi-Timbral Sound
Source
The PR-300S's sound source allows you to use up
to 15 different sounds and one drum kit
simultaneously (each of these sounds and drum kit is
controlled from a separate MIDI channel). This type
of arrangement is called "Multi-Timbral" because it
allows you to play multiple sounds at the same time.
About the Number of Notes that can be
Played Simultaneously
The PR-300S's sound source can play 28 sounds
at the same time. A single note playing an instrument
on a MIDI channel is usually considered "one sound",
although some instruments in the PR-300S's sound
source use "two sounds" per note.
When the maximum number of sounds (28) has
been exceeded, some sounds will be omitted. The GS
sound source gives priority to Parts as shown at right.
This Part priority determines which sounds will be
omitted when the song data calls for more notes than
are currently available. Sounds from Parts with the
lowest priority are omitted first. Make sure to use
Parts with a high priority for sounds which you don't
want to drop out. See the "Tone List" for more
information on how many sounds are used by each
instrument.
About Starting MIDI messages
When you make a song on the PR-300S, a GS
Reset message is automatically inserted at the
beginning of the sequence. This Reset message is a
SysEx message which tells the internal GS sound
source (and the sound source of any connected GS
equipment) to reset itself to initial (default) values.
Other song settings, such as Program Changes (to
select sounds for each Part), volume, panning, amount
of reverb and chorus are sent to the internal GS sound
source of the PR-300S based on the settings made in
the Sound Function.
