Note:
The RY20 can only receive bulk data while 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 transferred. The number of blocks transmitted or received
depends on the quantity of pattern and song data.
One byte of data is divided into 4bits MSB and 4bits LSB. It is then converted to
ASCII data for transfer.
A bulk dump consists of the following data:
System data
MIDI set-up data
Drum kit data
Pattern data
Song data
