4. Sample Dump
For the sample dump the SY85 uses the Sample Dump Standard and SY99 Sample Bulk Dump.
Both of them can be received.
For transmission, the above two data types are is transmitted successively when ﾒSample Dumpﾓ of the
Sample Utility is executed. When receiving Sample Dump Standard Dump Request, and SY99 Sample
Bulk Dump Request, each data type is transmitted.
With Sample Dump Standard and SY99 Sample Bulk Dump, $1f is the upper limit of the Sample (mem-
ory) Number and the number exceeding this is handled as $1f.

5.2 Channel message
Reception is carried out only during recording. Transmission is performed only when playing and over-
dubbing.
Refer to the Receive flow chart and Transmit flow chart for the transmission and reception conditions.
5.3 Mode message
Transmission and reception are not carried out.
5.4 System common message
Only $F2 is received and the others are not transmitted or received.
5.5 System real time message
5.5.1 Status F8, FA, FB, FC
are received.
5.5.2 Nothing is carried out with Status F9, FD, and FF after being read.
6. Status FE (active sensing)
a ) Transmission
FE is transmitted approximately every 170 msec.
b ) Reception
If a signal is not output from MIDI for longer than approximately 300msec after receiving FE, the
MIDI reception buffer is cleared, and if key on remains it is turned off.
