■CHANNEL MODE MESSAGE
●AllSound Off (Controller Number 120)
Status Second Third
BnH 78H 00H
n = MIDI Channel No.: 00H - 0FH (ch.1 - ch.16)
Received over the MIDI channel set with MIDI Channel. It causes all sounds to stop
sounding.
* For instructions on setting MIDI channels, refer to “How to Change the MIDI Channel”
in the Owner’s Manual (p. 53).
■System Common Message
●Song Position Pointer
Status Second Third
F2H mmH nnH
nn, mm = Song Position Point: 00H 00H - 7FH 7FH
When the MIDI Sync mode is set to “AUTO SYNC,” this is received if the pattern is
stopped. It sets the position from which the pattern is to be performed. If the Song Position
Pointer is at a point beyond the length of the pattern, then the Song Position Pointer is set at
the point where the pattern ends and the remaining patterns begin.
* For instructions on making the MIDI Sync mode settings, refer to “Using the SP-303
With a MIDI Sequencer (Tempo Sync)” in the Owner’s Manual (p. 54).

2. TRANSMITTED DATA
The SP-303 has no MIDI OUT connector, so no data is transmitted.
3. Supplementary material
●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
