Receiving system setup data by bulk dump: The
SY99 is capable of receiving all system setup
data which can be transmitted as a bulk dump.
However, the MDR/sample RAM memory allo-
cation setting will not be changed as the result
of an incoming bulk dump.
Receiving song data by bulk dump: When data for
a single song is received by bulk dump (whether
in K-Seq or N-Seq format), that song is auto-
matically assigned to the song number of the
currently selected song. Any sequence data for
the current song will be deleted by the incoming
data. Moreover, Next Song, Next Mode, and
PGM Select settings cannot be received as part
of a song data bulk dump; these items will retain
the values set for the previous current song, if
any.
