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.

Communication precautions
When linking together two D-Two devices for transfer of data, make sure that the receiving
device is set to receive only SysEx.
During MIDI operation the D-Two may present the following messages:
"> Preset Received <"
"> Preset Dumped <"
"> Rhythm Received <"
"> Rhythm Dumped <"
"> Checksum Error <"
">MIDI Error Occured<"
"> Event Unknown <"
"> Preset Stored <"
">Kernel Par Changed<"
"> Bulk In Progress <"

See below for a list of parameter identifiers. If a Parameter Data Request message requests a
parameter range extending across any undefined parameter identifiers, the corresponding
parameter values in the Parameter Data message should be ignored.

Parameters
Parameters can be changed by the System Data SysEx message (for system-parameters) or
hard-wired controller change messages (for the algorithm-parameters). Parameters are
always set as absolute 14-bit values.
The CC’s used for algorithm-parameters are as follows (ID's are given below):
System: Ctrl 16 + <ID>
Effect parameter : Ctrl 48 + <ID>
The System-parameter ID’s are used with SysEx-Cmd’s and the
controller parameters !

* Note that this value is created at the time when the rhythm is tap’ed and is used for timescaling relative to base-tempo. When a rhythm is tap’ed the Rhythm-scale-base equals Basetempo. Therefore this parameter is ONLY directly available through SysEx-control of Rhythms
and should NOT be updated via Midi-CC.
