(*5) Depending on the pad assignments that are saved within the TD-50 for
digitally-connected pads, this area will be as follows.
Addresses for which the digitally-connected pad has no assignment are
ignored.
Normally you should edit these parameters from within the TD-50 itself.

7Decimal and Hexadecimal Table
(An “H” is appended to the end of numbers in hexadecimal notation.)
In MIDI documentation, data values and addresses/sizes of exclusive messages etc.
are expressed as hexadecimal values for each 7 bits.
The following table shows how these correspond to decimal numbers. (in the case of
hexadecimal values for each 7 bits, or positive hexadecimal values for each 4 bits.)

D: decimal
H: hexadecimal
* Decimal values such as MIDI channel, bank select, and program change are listed as
one greater than the values given in the above table.
* A 7-bit byte can express data in the range of 128 steps. For data where greater
precision is required, we must use two or more bytes. For example, two
hexadecimal numbers aa bbH expressing two 7-bit bytes would indicate a value of
aa x 128+bb.
* In the case of data to which multiple addresses are assigned, a hexadecimal value
is used for each four bits. A value 0a 0bH expressed as two-byte nibbles will be
a×16+b.
* For signed values with a ± symbol, positive values are expressed as a hexadecimal
value for each four bits, and negative values are expressed as the two’s
complement of the hexadecimal value for each four bits. As some example
expressions for negative values, two bytes would be 0F 0FH= -1, and four bytes
would be 0F 0F 09 0C= -100.
<Example 1>
What is the decimal expression of 5AH?
From the preceding table, 5AH = 90
<Example 2>
What is the decimal expression of the value 12 34H given as hexadecimal for each
7 bits?
From the preceding table, since 12H = 18 and 34H = 52
18 x 128 + 52 = 2356
<Example 3>
What is the decimal expression of the nibbled value 01 02 0C 00?
From the preceding table, since 01H = 1, 02H = 2, 0CH = 12, 00H = 0
((1 x 16 + 2) x 16 + 12) x 16 + 0 = 4800
<Example 4>
What is the nibbled expression of the decimal value 1258?
16) 1258
16) 78 ... 10
16) 4 ... 14
0 ... 4
Since from the preceding table, 0 = 00H, 4 = 04H, 14 = 0EH, 10 = 0AH, the result is: 00
04 0E 0AH.
