Preparing The GM-70 To Control an RA-50:
1) Press GENERAL EDIT and the GM-70's display will change to: ??A PROGRAM= ??
2) Press the FUNCTION down button once and use the VALUE buttons to set the
MIDI mode to POLY.
3) Press the FUNCTION down button one more time and use the VALUE buttons to
set the MIDI channel to 1.
4) Press the FUNCTION down button one time so that the [A] is flashing and
use the VALUE up button to access branch [B]. Use the FUNCTION and VALUE
buttons to select [CHANNEL=4 POLY].
5) Press the INDIVIDUAL EDIT button.
6) Use the FUNCTION button to scroll between string number [1/2/3/4/5/6] and
string select [ON/OFF]. Turn the string select [OFF] on strings [1/2/3] so
that only the low three strings trigger the arranger. The displays will look
as follows:
A 1 OFF PG 0
A 2 OFF PG 0
A 3 OFF PG 0
7) Press the FUNCTION button and the VALUE button to select branch [B].
8) Use the FUNCTION button to scroll between string number [1/2/3/4/5/6] and
string select [ON/OFF]. Turn the string select [OFF] on strings [4/5/6] so
that only the high three strings play the upper/solo part. The displays will
look as follows:
B 4 OFF PG 0
B 5 OFF PG 0
B 6 OFF PG 0
9) We have now programmed the GM-70s external branches to control the
RA-50. Use the write procedure, on page 20 of the GM-70s owners manual, to
save this setup into a patch memory. You will then need to repeat this
procedure for every patch that you use to control the Intelligent Arranger.
