Using Program Changes with Variation Select Messages
In the previous pages, you've learned how to select
PR-300 sounds using 128 different Program
Change messages. You've also learned how to
store these Program Changes into the combination
action of the organ, making it easy to change
sounds quickly.
However, the PR-300 has more than 128 sounds in
its GS sound generator (in fact, it has 317 different
instruments and 10 different drum kits to choose
from). You can select any of these instruments
using the Sound Function, but Program Changes
alone will only allow you access to 128 of the
voices in the PR-300.
For this reason, some Rodgers organs use
Variation Select messages to allow access to all
PR-300 sounds. The combination of Variation
Select messages and Program Change messages
allows you to select any of the PR-300 sounds from
a Rodgers organ.
What's more, Variation Select messages can be
stored in the combination action with Program
Changes, so both messages can be sent from the
organ to the PR-300 with the press of a piston.
