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 1to
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 areceiving 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 afew 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 4and 5with the screening connected to pin 2.
Section 8in the annex contains further details on programming MIDI for
data input and output and data format.
3.4 Cassette Recorder Connections CASSETTE TO/FROM
Acassette 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 8individual jack cables when triggering the ADD-one
from asequencer for example, this jack provides asimple means of
coupling devices with only asingle 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-ANNEX.
