* The SP-505s sequencer stores performance data as packages consisting of Note On/Off
data and Program Change data. It is not possible to store Program Change data by itself.'

Decimal/Hexadecimal table
(hexadecimal values are indicated by a following H)
MIDI uses 7-bit hexadecimal values to indicate data values and the address and size of
exclusive messages. The following table shows the correspondence between decimal and
hexadecimal numbers.

D: decimal
H: hexadecimal
* Decimal expressions such as used for MIDI channel, Bank Select, and Program Change
will be the value 1 greater than the decimal value given in the above table.
* Since each MIDI byte carries 7 significant data bits, each byte can express a maximum of
128 different values. Data for which higher resolution is required must be transmitted
using two or more bytes. For example a value indicated as a two-byte value of aa bbH
would have a value of aa x 128 + bb.
* For a signed number (+/-), 00H = -64, 40H = +/-0, and 7FH = +63. I.e., the decimal
equivalent will be 64 less than the decimal value given in the above table. For a two-byte
signed number, 00 00H = -8192, 40 00H = +/-0, and 7F 7FH = +8191. For example the
decimal expression of aa bbH would be aa bbH - 40 00H = (aa x 128 + bb - 64 x 128.
* Hexadecimal notation in two 4-bit units is used for data indicated as nibbled The nibbled
two-byte value of 0a 0b H would be a x 16 + b.
<Example1>
What is the decimal equivalent of 5AH?
From the above table, 5AH = 90.
<Example2>
What is the decimal equivalent of the 7-bit hexadecimal values 12 34H?
From the above table, 12H = 18 and 34H = 52
Thus, 18 x 128 + 52 = 2356
<Example3>
What is the decimal equivalent of the nibbled expression 0A 03 09 0DH?
From the above table, 0AH = 10, 03H = 3, 09H = 9, 0DH = 13
Thus, the result is ((10 x 16 + 3) x 16 + 9) x 16 + 13 = 41885
<Example4>
What is the nibbled equivalent of the decimal number 1258?
16 )1258
16 ) 78...10
16 ) 4...14
0... 4
From the above table, 0=00H, 4=04H, 14=0EH, 10=0AH
Thus the result is 00 04 0E 0AH
