Preset numbers
Preset numbers are represented in the SysEx messages as 2 bytes (14-bit value). The first
byte is the 7 most significant bits and the second byte is the 7 least significant bits.
Preset numbers are mapped accordingly:
0x01 (1) to 0x32 (50) Factory bank
0x33 (51) to 0x96 (150) User bank
Preset number 0 is used to access the edit buffer. When recalling presets with program
changes, sending a controller 0 or controller 32 change first can be used to indicate bank
number (when sending other than zero selects user-bank as opposed to factory-bank).
Binary data
Messages containing binary data dumps consists of a set of 14-bit values as 2-byte pairs The
most significant byte is sent in the first byte and the least significant in the second. The dump
is terminated with a 14-bit checksum value which is the negative sum of all bytes in the dump
truncated to 14 bits. ie. (-sum(all data bytes)) & 0x3FFF.
