The MIDI CH button accesses 7 different parameters that can be selected and
programmed in the same was as the voice editing parameters. The 7 MIDI para-
meters can be selected in sequence by pressing the MIDI CH button (the letter
representing the selected function will flash), and the setting of the selected
parameter can be changed by using the -1 and +1 buttons or by directly entering
the value. In the case of "MIDI Channel," use the number buttons (0 through 9).

This parameter simply turns the DS55's MIDI functions "on" or "off." Turn "on" if
you will be using the DS55 with other MIDI devices, or "off" if you do not want
the DS55 to respond to'external MIDI control or transmit MIDI data. If MIDI Switch
is "off," none of the following parameters can be selected.
The MIDI system allows transmission and reception of MIDI data on 16 different
channels. Multiple channels have been implemented to allow selective control of
certain instruments or devices connected in series. For example, a single MIDI
sequence recorder could be used to "play" two different instruments or tone
generators. One of the instruments or tone generators could be set to receive only
on channel 1, while the other is set to receive on channel 2. In this situation the
first instrument or tone generator will respond only to channel-1 information trans-
mitted by the sequence recorder, while the second instrument or tone generator
will respond only to channel-2 information. This allows the sequence recorder to
"play" two independent parts on the receiving instruments or tone generators.

In any MIDI control setup, the MIDI channels of the transmitting and receiving
equipment
must be matched for proper data transfer. Use the -1 and +1 or
number buttons to set the desired MIDI transmit/receive channel on the DS55.
The "Omni" receive mode allows reception on all 16 MIDI channels simultane-
ously. In the Omni mode it is not necessary to match the receive channel of the
receiving device to the the transmit channel of the transmitting device. The Omni
parameter can be turned "on" or "off." When "off," the DS55 will respond to data
on the single MIDI channel selected with the MIDI Receive Channel parameter.
The Exclusive parameter determines whether the DS55 will transmit and receive
MIDI System Exclusive Data. System Exclusive Data includes the actual voice data
used by the DS55, so this parameter must be turned "on" if you intend to receive
voice data from external equipment, or transmit DS55 voice data to other equip
