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).

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.

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

XG SYSTEM 00
EFFECT 1
PART
SOUND LISTS & MIDI DATA
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.
