ADD-one MANUAL
SECTION
3
OMNI MODE:
In
this mode, the
receiving units will ignore
all MIDI channel
commands, but will execute all other incoming MIDI commands.
The
sending MIDI units will
add the MIDI channel number
1
to
all MIDI
commands. This
is
the "lowest"
application level
as
although
all data can
be
transmitted, they cannot
be
assigned
to
specific channels.
POLY
MODE:
In
this mode, the
receiving
MIDI units will only
respond
to
commands which are assigned
to
the MIDI
channel number
pre-_
selected
as the
receive channel
on the
receiving
unit.
Sending
units may add different channel numbers
to
their commands.
This
application
level
is
somewhat "higher" than
in
OMNI
as
specific channels,
in
which
for
example something
is to
change, can
be
directly addressed without affecting any
of the
others
MONO
MODE:
In
this mode, each
voice
of
a
receiving
MIDI unit can be
addressed individually via
one MIDI channel. This
is
the
most
sophisticated level
of
application and
is
at
present, however,
only possible with
a
few units.
MIDI wiring
is
always
completely
separate from
the the
audio wiring.
The
MIDI input lines are
electrically isolated from
the
circuit chassis which
means that MIDI will cause
no
ground
loops. The length of the MIDI cable
should not exceed
15 m.
Use only
screened microphone cables with 5-pole
DIN plugs. Unlike normal microphone wiring, conductors here must
be
soldered
to
pins
4
and
5
with
the
screening connected
to
pin
2.
Section
8
in
the
annex contains further details
on
programming
MIDI
for
data input and output and data format.
3.4
Cassette Recorder Connections CASSETTE TO/FROM
A
cassette recorder
or
other tape device
can be
connected
to
these two
CINCH jacks
to
record program
data, i.e.
to
read out the contents
of the
internal program memory
of the
ADD-one
and,
for example,
write earlier
program
data back into the memory of the ADD-one.
In
the
latter case,
however, data currently resident
in
the
memory will
be
overwritten
and
lost. The record jack of the recorder must be
connected
to
the
"CASSETTE
•~
^"
jack on the
ADD-one and
the
play-back
jack on the tape
device
to the
-ASSETTE
FROM" jack. The
recording and play-back
level must be
appropriately adjusted
on the tape device.
3.5 The
MULTI TRIGGER IN/ OUT Jack
To
avoid
the use of
8
individual
jack cables
when triggering
the
ADD-one
from
a
sequencer
for
example, this jack provides
a
simple means
of
coupling devices with only
a
single multicore cable. Coupling
the
DYNACORD
"BIG BRAIN"
with
the
ADD-one presents
no
problem;
as far as the
connection
of
other sequencers
is
concerned, refer
to the
wiring
assignment
of the
15-pole Cannon
jack
in
Section
8
