equivalent to address ‘0’ if you were using checksums.
The DMX-512 checksums should be enabled if the DMX-
512 that is sent to the Mp3-50/8 or Mp3-50/40 is coming
from ANY piece of Gilderfluke & Company equipment. The
checksums assure that the Mp3-50/8 or Mp3-50/40 will not
update its outputs on ‘bad’ data.
b) MIDI Notes: The switch on the bottom of the Mp3-50 must
be in the optoisolated/Low-z position to be used for MIDI.
The MIDI should be fed to the Mp3-50/8 or Mp3-50/40 as
follows:
MIDI pin #1 = no connection
MIDI pin #2 = no connection
MIDI pin #3 = no connection
MIDI pin #4 into - DMX/MIDI In
MIDI pin #5 into + DMX/MIDI In
The Mp3-50/8 or Mp3-50/40 will respond to MIDI ‘Note
On’, ‘Note Off’, ‘Reset’, ‘All Notes Off’ and ‘All Sounds Off’.
Running commands for ‘Note On’ and ‘Note Off’ com-
mands are accepted. All other defined MIDI commands
should be received and properly ignored. There are two
ways the Mp3-50/8 or Mp3-50/40 can be configured to re-
spond to MIDI Note commands.
1) When ‘MIDI Notes Trigger Animation’ checkbox is OFF,
then MIDI is used to directly access the Show Control
Outputs and Mp3 audio files:
a) Any MIDI notes which are below the number
you have set for the ‘MIDI Offset’ are ignored.
b) The next eight (Mp3-50/8) or forty (Mp3-50/40)
MIDI notes are mapped directly to the 8/40
Show Control outputs. These can be used to
ring mechanical bells or control animation di-
rectly from MIDI notes.
c) The next eight MIDI notes are sent to the ‘MPU
Interface’ to select and trigger audio files,
mute, and otherwise control the Mp3 Player.
d) The remaining notes are used to directly select
and play individual AudioFiles stored on the
Mp3 Player. Only note ‘On’ MIDI commands will
have any effect on selecting and playing Au-
dioFiles. The ‘velocity’ of the note will set the
playback level of the triggered AudioFile, if Re-
