■ Using MIDI Messages to Select Instruments
from Other Devices or Sequencing Software
You can use sequencing software on your computer to select the SC-8850’s sounds.
You can specify sounds by inputting the Variation number and the Instrument
number (p.40) into your sequencing program, but depending on your software the
way in which numbers are displayed may differ, so be aware of this. On the SC-8850,
Variation numbers begin with 0, and Instrument numbers begin with 1.
Variation numbers correspond to MIDI Bank numbers, and Instrument numbers
correspond to MIDI Program numbers.

Actual MIDI Messages
When creating MIDI messages on a sequencing program and transmitting them, use
the following procedure.
[1] The value of Control Change 0: MIDI Bank number (upper) (the SC-8850’s
Variation number)
[2] The value of Control Change 32: MIDI Bank number (lower)
(0: map setting on the panel, 1: SC-55 map,
2: SC-88 map, 3: SC-88Pro map, 4:SC-8850
map)
[3] Program Change value: MIDI Program number (the SC-8850’s In-
strument number)
* For details, refer to the following section Bank Select LSB.
[1] and [2] are the Bank Select message. Bank Select messages are a type of Control
Change message (p.149), and the Bank Select processing will be suspended until a
Program Change message is received.
For example, if you wish to select the Instrument (Piano3w) with Variation number
8, Instrument number 3, you would transmit the following data to the SC-8850. (Ex-
pressed in decimal notation.)
[1] The value of Control Change 0:
008 (Bank number (upper) 8; Variation number 8)
[2] The value of Control Change 32: 0
[3] Program Change value: 002 (Program number 3: Instrument number 3)
MIDI Bank numbers have
an upper (MSB) and lower
(LSB) part. Each can specify
a number 0-127, allowing
you to specify 128 x 128 =
16384 banks. The upper
part of the Bank number
corresponds to the SC-8850
Variation number. The
lower part switches
etween SC-55 map, SC-88
map, SC-88Pro map, and
SC-8850 map. (MIDI Imple-
mentation, p.226).
If you specify an
Instrument number that the
SC-8850 does not have, a
sound will not change.
Refer to Instrument List on
p.167 when selecting
sounds.
