MIDI SPECIFICATIONS
• Note 9 - Sound Sets
A Planet Phatt sound set consists of sample data (sound ROMs), plus
additional instrument data in the program ROMs. Each sound set has
a unique ID number. The sound sets for Planet Phatt are #13 & #14.
It is necessary to include the sound set number as part of the instru-
ment number when exchanging data. The complete instrument num-
ber contains two fields: bits 8-12 specify the sound set (0-31) and bits
0-7 specify the instrument within the sound set (0-255).
Instrument Bit Fields:
12
8
7
0
<— sound set —> <——— instrument # ———>
(5 bits)
(8 bits)
Within any given sound set, the first instrument is #1 and #0 selects
“None”.
The “magic numbers”
3328 & 3584
represents the start number for
the two banks of Planet Phatt instruments. To calculate the complete
instrument number follow the instructions below.
SysEx Instr. No.
(Bank 1)
= 3328 + Planet Phatt Instr. No.
Next you must convert the SysEx instrument number to a 14-bit MIDI
number. See the information on the following pages.
Example:
Suppose we want to change the instrument to
I003
SE Sub 3
1)
3328 + 3 =
3331
(3328 + Instr. No.)
2)
3331
÷
128 = 26 r-3 =
26
(ignore remainder)
3)
26 in Hex =
1A
= msb
4)
remainder 3 in Hex =
03
= lsb
5)
SysEx Instrument Number = lsb
