Bulk data consists of a
Song Header and the data
for 8 songs. The data size
is fixed at 6bAOH bytes.
The length of the Header is
fixed as the first 16 bytes 60200
at the top of each song
data. The data length of
each song is variable. An
unrecorded area (the area
between Write Position
Data and Read Position
Data) exists somewhere in
the data for the 8 songs,
but only as long as the
capacity for further record-
ing remains. When the
bulk data is dumped, this
unrecorded area is located
in the song selected using
the PSS-51 panel controls.
The position of this area in
the song is also shown by
the measure number.
Once you upload the bulk
data back onto the PSS-51
however, the position of the
area will be reset to the top
of the song.
