The RY8 can receive bulk data only when it is in Pattern or Song Select
Mode.
A block consists of the Byte Count, the data bytes, and the Checksum.
A number of blocks are repeatedly transmitted.
One byte of data is divided into 4bits MSB and 4bits LSB. It is then
converted to ASCII data for transmission.
A bulk dump consists of the following data:
System Data
MIDI Set-up Data
Drum Kit Data
Pattern Data
Song Data
s=0~99
Device Number (Fixed at 00H)
