Playing Sounds Of The; Playing The Pr-300 Os Sound Module - Rodgers PR-300 Owner's Manual

Playing Sounds of the PR-300
The PR-300 has 317 high quality sounds which can be used to create many different styles of music. In this
section, we'll show you how to play PR-300 sounds from another MIDI device, such as a Rodgers organ or
MIDI keyboard.
We'll also tell you about the different ways that sounds can
be
selected.
MIDI Channel Groups
Playing the PR·300 GS Sound Module
The PR-300 is equipped with a high resolution sound generator
which produces many great sounding instruments and effects
(you've already heard some of them by listening to the demo
disk). This sound generator conforms to both the new General
MIDI Specification and the new GS Format
MIDI uses 16 different channels to communicate. Each of these
channels can be used to control a different sound.
When the PR-300 is connected to a MIDI synthesizer or
keyboard (such as the Rodgers C-100 or C-220), each of the 16
MIDI channels can be used to control EITHER a PR-300 sound
or a sound in the MIDI keyboard.
So that the resources of both the PR-300 and the MIDI keyboard
can be utilized, some of the 16 MIDI channels are designated for
PR-300 use only, and some of the 16 MIDI channels are
designated for MIDI keyboard use only.
For example, when the PR-300 is connected to a Rodgers organ,
some MIDI channels are used to control PR-300 sounds and
some MIDI channels are used to control the organ's sounds.
To use the resources of both instruments together, the PR-300
must be told which of the 16 MIDI channels will be used to
control the PR-300's internal sounds and which will be used to
control sounds in an external MIDI instrument (such as a MIDI
keyboard or Rodgers organ).
GENERAL
mlill
Channels Common Use
These channel assignments are determined by two switches on
the PR-300; one determines how channels 1-10 will be used, the
other how channels 11-16 are used. Each of these two groups of
MIDI channels can be set to "External" or "Internal". If a group
of MIDI channels is set to "External", then those channels will be
used to control external equipment.
If the group is set to
"Internal", then the channels will be used to control the internal
sounds of the PR-300.
