A MIDI equipped synthesizer such as the POLY-8OO is used
to input key data to the digital sequencer. The POLY-8OO can
then be disconnected from the digital sequencer (broken line).
Decide beforehand whether you are going to use the EX-800
in the 4-voice or 8-voice (DOUBLE or WHOLE) mode and in
put data accordingly. If the digital sequencer is a multi-track
model then be sure to set EX-800 RCV CH value to the ap
propriate channel number (1 -16) after turning on EX-800
power.
(Refer to the digital sequencer’s owner’s manual for particu
lar details.)

(The number of notes storable and played varies according
to the software being used. Also, please remember that the
EX-800’s “DCO-MODE” parameter (parameter # 18) controls
how many notes each EX-800 can sound simultaneously (ei
ther 4 or 8), and care should be taken to select programs with
sufficient notes capabilities for the desired music.)
For timing reasons, instruments connected via the MIDI-THRU
jacks should be limited to four, or possible malfunction may
occur. More than four instruments should be connected us
ing a “MIDI-Through Box”.

Box
In this system, full use is made of MIDI channels 1 through
16 via use of a MIDI “Through Box”. Furthermore, a MIDI Syn
chronizer device (KORG KMS-30) is used to synchronize the
timing of rhythm machines (e.g. KORG DDM-110, DDM-220,
KPR-77, and other device with “Sync” connection) to the se
quencer. The KNS-30 can also be used to perform a “Sync
to Tape” function for driving all synthesizers, rhythmers etc.
from one track of the tape recorder.
This type of system makes it possible to perform music with
complex arrangements and orchestrations.
This is an example of a system using a “personal computer”
with a MIDI Interface device, and commercially available soft
ware to automatically play four EX-800 Modules. The data is
written into the computer’s memory in accordance with the
respective software’s instructions, and is saved on tape or Dis
kette. The finished piece is then played back by the four
EX-800s, under the computer’s control.
NOTE:
When an EX-800 is first turned on, its mode is set to receive
data on all channels. However, if you are going to use sever
al EX-800s (other MIDI synths, drum machines, and so on)
under the control o f a multi-channel sequencer or computer,
then it is necessary to send mode messages to the EX-800s
to change them to the MULTI CH mode. It the sequencer
or computer can not send such messages then selecting the
85 parameter number will automatically change to the
MULTI CH mode.
To get out o f this mode you can turn the Ex-800 o ff or send
it a mode message to return to its default condition.
