Midi channel number, Midi first note number, Net serial mode – Gilderfluke&Co Sd-50 Audio & Show Controllers User Manual

Level Controls have been enabled, the ‘Note On’ velocity is used to set the .Mp3/.wav
player level. The MIDI ‘Note On‘ velocity of 1 through 127 translates to volume levels from
0% through 100%.
d) Notes after the last SoundFile are ignored.
2) The second mode, selected when this checkbox has been checked, uses MIDI to trigger prepro-
grammed animated shows stored in the Show Control Flash memory. The shows are programmed
normally, using PC•MACs, and downloaded to the Sd-50/8 or Sd-50/40 before this mode will work.
Each time a show is started, the DMX/MIDI/Serial LED fill flash for an instant. Starting with the first
MIDI note set by the ‘Animation First Note Number:
a) The very first ‘Note’ will trigger the Show Control side of the Sd-50/8 or Sd-50/40 with a
‘whatever is next’ show request. The ‘Whatever is Next’ is set for each show at the time
the show files are downloaded from PC•MACs.
b) Each note will trigger a specific animated show. Up to 127 shows can be accessed in this
way.
c) Show numbers beyond the last show loaded on the Sd-50/8 or Sd-50/40 are ignored.

MIDI Channel Number
data stream can be addressed to any of sixteen different addresses. These are typi-
cally set to choose which ‘instrument’ the data is being sent to. This sets which of these sixteen
addresses the Sd-50/8 or Sd-50/40 will be sent to. Valid values are from 1 through 16. Potentially,
up to sixteen Sd-50/8 or Sd-50/40 can be controlled on the same MIDI line.

MIDI First Note Number
Legal
notes are numbered from 00h through 7Fh (0 through 127 in decimal numbers).
The only problem is that if you are actually using a keyboard to access the Sd-50/8 or Sd-50/40, no
keyboards actually have all 128 keys. A real piano has only 88. ‘Middle C’ is located at 3Ch (or 60
in decimal numbers) on all MIDI keyboards. You can count to the West and East of ‘Middle C’ to
determine what numbers your keyboard will actually generate.
Numbers below the value you set for the ‘MIDI Note Offset’ will be ignored. If you wanted to
start accessing the features of the Sd-50/8 or Sd-50/40 at ‘Middle C’, you would set this offset to
3Ch (or 60 in decimal numbers).
d)! Net Serial Mode
$
$
Turning this mode on disables
and
input on the
. Data output from the DMX-512/MIDI serial port will be buff-
ered and repeated, but otherwise an unaltered version of what is received on the input.
This enables a mode which sets the DMX-512/MIDI serial port to 9600 baud and parallels the data re-
ceived with that from the RS-232 serial port. This mode allows just about any number of Sd-50/8 and Sd-
50/40s to be controlled in parallel off the same RS-422 serial port.
All the standard serial port commands are valid through the Net Serial port. Since it is only a networked
‘receive’ port, you will not get any echoes or response through the DMX-512/MIDI out port. If you do attach
a RS-232 serial terminal to the normal RS-232 serial port, you will see all responses and menus displayed
there just as if the commands had come in through the RS-232 serial port.
At 9600 baud, the input can use the optoisolated or RS-422 switch settings for the DMX-512/MIDI
ports.
