REFERENCE SECTION
• To go the other way (convert 14-bit
signed 2’s complement to a signed real
number)
raw Value
= (msb*128) + lsb (gives you
the unsigned raw value)
if raw Value
≥
8192 (8192 = 2^13)
then signed Value = raw value - 16384
(16384 = 2^14)
Example:
To find the “nibble-ized” Hex
value of -127:
1) -127 + 16384 = 16252
2) 16252 ÷ 128 = 126 r-124
3) 126 in Hex = 7E = msb
4) 124 in Hex = 7C = lsb
5) Parameter value would be transmitted
as 7C 7E
Example:
To find the “nibble-ized” Hex
value of parameter number 257:
1) 257 ÷ 128 = 2 r-1
2) 2 in Hex = 02 = msb
3) 1 in Hex = 01 = lsb
4) Parameter number would be
transmitted as 01 02
NOTE 3 - VERSION REQUEST
This command allows identification of
machine type and software revision.
Proteus FX will respond to the request
with the version data:
F0 18 04 dd
OB
01 r1 r2 r3 F7
r1, r2, r3 =software revision number in
ascii (decimal point between r1 & r2).
NOTE 4 -CONFIGURATION REQUEST
This MIDI command is used to identify
the sound sets in a given Proteus FX. The
configuration request command is:
F0 18 04 dd OC F7
Proteus FX will respond to this command
with the configuration message:
F0 18 0A dd 0D pl pm s1 l1 m1 s2 l2 m2 F7
where pl and pm are the lsb and msb are
the total number of presets, s1 and s2 are
the ID numbers of the sound sets con-
tained in this unit, and n1=l1, m1 and m2
= l2, m2 represent the lsb and msb of the
number of instruments in each sound set.
NOTE 5 - BULK TUNING DUMP
Proteus FX can receive MIDI Tuning
Standard dumps in addition to its own
SysEx tuning table dumps. Proteus FX
will only transmit in it’s own SysEx
tuning format. The MIDI Tuning Stan-
dard is as follows:
F0 7E dd 08 01 tt <tuning name (16
ascii)> … F7
dd= device ID tt= tuning prog #
(ignored) tuning name = (ignored)
…
= data (xx yy zz) frequency data for
one note repeated 128x
xx yy zz = 0xxxxxxx 0abcdefg 0hijklmn
xxxxxxx = semitone abcdefghijklmn =
fraction of semitone in .0061 cent units.
Examples: Middle C = 3C 00 00 A-440 =
45 00 00
