Radio Shack MD-1210 Video Game Keyboard User Manual

Using MIDI
Notes:
• The keyboard’s prerecorded tunes
cannot be sent as MIDI data.
For detailed specifications of the
MIDI function, see the “MIDI Imple-
mentation Chart” on Page 46.
Note On/Off
— specifies which keys are
pressed (Note On) or released (Note
Off). Also includes how loud a note is
played as a value from 0 to 127.
Notes:
The pitch of a note depends on the
tone that is being used, as shown in
the “MIDI Implementation Chart” on
Page 46.
If the keyboard receives a “request”
to play notes outside of its range
(higher or lower), it automatically
selects the same note in the nearest
octave.
Program Change
— specifies the tone.
Pitch Bend
— supplies pitch bend infor-
mation. The keyboard’s pitch changes
as it receives a Pitch Bend message
through the
MIDI IN
terminal, and the
keyboard sends pitch bend information
through the
MIDI OUT
terminal as you ro-
tate
PITCH BEND
.
Control Change
— adds effects such
as vibrato and volume changes applied
during keyboard play. The message in-
cludes a control number (the effect type)
and a control value (the on/off and depth
of the effect).
Here is the data that can be received
with this keyboard and the correspond-
ing control number.
Use the Bank Select setting to select the
keyboard’s tone groups to be changed
by the Program Number message.
Bank 0 — 0 to 127 (General MIDI
tones)
Bank 1 — 128 to 159 (synthesized
tones)
Bank 2 — 160 to 167 (drum sets)
Bank 3 — 168 to 199 (user tones)
Just before sending a Program Change
message, send two Control Change
messages with this data to the key-
board:
Control Number = 0, Control Value =
<bank number>
Control Number = 32, Control Value
= 0
For example, to select tone number 190
(user tone number 22), enter:
Control Number = 0, Control Value =
3 (bank number for user tone)
Control Number = 32, Control Value
= 0
