Radio Shack MD-1210 Video Game Keyboard User Manual


 
37Using MIDI
Program Change = 22 (22nd tone in
bank 3)
Note:
Channel 10 is reserved for drum
sounds only, so it is not necessary to
send bank select data when changing
tones.
RPN is used when combining multiple
control changes. RPN (100 and 101) se-
lects the parameter to control, and Data
Entry (6 and 38) sets the contents of the
parameter. On the keyboard, RPN is
used to set pitch bend range, transpose,
and tune control from an external MIDI
device.
All Sound Off
forces all sound on the
current channel to turn off, regardless of
how the sound is being produced.
All Notes Off
turns off all note data sent
from an external device on the channel.
The notes being sustained by the pedal
continue to sound until the next pedal off
signal is received.
Reset All Controllers
initializes pitch
bend and all other control changes.
System Exclusive
controls fine tone
adjustments unique to a particular sys-
tem. The system exclusives are unique
to a particular system; however, there
are “universal” system exclusives that
are common among devices produced
by individual manufacturers.
These are the system exclusive mes-
sages supported by this keyboard.
GM Mode On ([F0][7E][7F][09]
[01][F7])
— used to turn on the key-
board’s GM (General MIDI) mode
from an external MIDI device.
Notes:
GM is a standard list of specifica-
tions that allows music created on
one MIDI device to sound the
same when played on another
MIDI device. This keyboard’s GM
mode incorporates most of these
specifications.
This message takes more time to
process than other messages;
when you program GM Mode On
in the sequencer, leave at least a
100 msec pause before the next
message.
GM Mode Off ([F0][7E][7F][09]
[02][F7])
— used to turn off the key-
board’s GM mode.
Reverb Change ([F0][44][0E][09]
[yy][F7])
— switches the keyboard’s
reverb function. yy determines the
type of reverberation effect.
Note:
The contents of the System Ex-
clusive message affect the entire key-
board. Other messages affect only the
current MIDI channel.
