• 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
<— sound set —> <——— instrument # ———>
(5 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.)
3331 ÷ 128 = 26 r-3 = 26 (ignore remainder)
2)
3) 26 in Hex = 1A = msb
4) remainder 3 in Hex = 03 = lsb
5) SysEx Instrument Number = lsb
The complete message to change the primary instrument to #03:
F0 18 0A dd 03 17 00 03 1A F7
