Using MIDI messages to select sounds

By sending MIDI messages from a MIDI keyboard or sequencer, you can remotely

select the sound (Instrument) for each Part. When you press a sound select button on a
MIDI keyboard, a MIDI message selecting a sound will be transmitted

You can also use your personal computer to select this unit sounds. You can specify

sounds by inputting the Variation number and the Instrument number (p.21) into your
computer program, but depending on your software the way in which numbers are dis-
played may differ, so be aware of this. On this unit, Variation numbers begin with 0, and
Instrument numbers begin with 1.

Variation numbers correspond to MIDI Bank numbers, and Instrument numbers cor-

respond to MIDI Program numbers.

*

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 cor-
responds to this unit Variation number. The lower part switches between SC-55 map, SC-88
map and Native map. (MIDI Implementation, p.188).

*

For the relation between the sound names and program numbers of your MIDI keyboard, refer
to the manual for your MIDI keyboard.

*

If you specify a sound number that this unit does not have, a sound will not change. Refer to the
instrument table on p.154 when selecting sounds.

When creating MIDI messages on a sequencer or personal computer and transmit-

ting them, use the following procedure.

1. The value of Control Change 0

: MIDI Bank Number (upper) (this unit's

Variation number)

2. The value of Control Change 32

: MIDI Bank Number (lower)

3. Program Change value

: MIDI Program Number (this unit's instru-

ment number)

1. and 2. are the Bank Select message. Bank Select messages are a type of Control
Change message (p.131).

For example if you wish to select the Instrument (Piano3w) with Variation number 8,

Instrument number 3, you would transmit the following data to this unit.
(Expressed in decimal notation.)

1. The value of Control Change 0

: 8 (Bank number (upper) 8; Variation number 8)

2. The value of Control Change 32

: 0

3. Program Change value

: 2 (Program number 3 : Instrument number 3)

*

Note that the data actually transmitted as the Program number will be one less than the
Program number.
