SOUND LISTS & MIDI DATA

513 bytes or more shall not be received at one time. Thus,

if a dump request for 513 bytes or more is received, the data

must be divided into packets of 512 bytes or less, and the

packets transmitted with an appropriate time interval (120

msec or more).

3.2.1.1 XG System Data bulk dump

Refer to tables <1-1> and <1-2>.

3.2.1.2 Multi Effect1 Data bulk dump

For the Address and Byte Count, refer to the accompanying

tables.

Check sum is the value which produces a lower 7 bits of

zero when the Start Address, Byte Count, and Check-sum

itself are added.

513 bytes or more shall not be received at one time. Thus,

if a dump request for 513 bytes or more is received, the data

must be divided into packets of 512 bytes or less, and the

packets transmitted with an appropriate time interval (120

msec or more).

4. Realtime Messages

4.1 Active Sensing

Once FE has been received, failure to receive subsequent

MIDI messages for an interval greater than approximately

300 msec will cause

the same processing to be performed as when SOUND OFF,

ALL NOTE OFF, and RESET ALL CONTROLLERS are

received, and then the instrument will return to the status of

not having received FE.

5. MIDI thru out

MIDI data that is received is re-transmitted (thru out) in the

following 2 modes.

5.1 When MIDI OUT=ot1

Data received at MIDI IN is re-transmitted (thru out) with-

out change.

5.2 When MIDI OUT=ot2

Data other than Key ON/OFF messages of the receive chan-

nel specified by MIDI CH will be re-transmitted (thru out).

However if the Receive Channel is set to ALL, or if the

voice number is 29 (Silence), all data will be re-transmitted

(thru out) without change.

When the setting is changed from ot1 to ot2, the change is

made simply, without performing any management of notes

which may be currently on. In some cases this can cause

problems; switching the setting to ot2 while notes are on

can cause stuck notes on a tone generator connected to

MIDI OUT.
