select Periodically. A Repeat Response Period window will display allowing you to define
how often the event will be repeated. In our case, we will use the up arrow key in the days
display to define that we want the event to take place every 7 days. Note that after clicking
on the OK button, details of each event parameter are displayed to the right of the window.
We can choose to log the event to NexSys event monitor at each execution, or not. Click on
the log button at the bottom of the window if you want to log the event. Click the OK but-
ton and now our event is defined.
In the Event Scheduler window, we can perform any number of operations on this or any
other event by highlighting the event (single click), then choose to Do Now, Edit the event,
or Delete the event if it is no longer needed.
Most of the triggers and actions are intuitive and don't require anything more than selection
from the options listings. The MIDI message option is an exception. If you want to trigger
an event or report a message out of the system via the MIDI interface additional definitions
are required.
If you want to receive a MIDI message to trigger an event you must select the following:
Event | New
Give the event a name.
On/At
Enter the address of the MIDI interface as it appears on the NexSys data bus. This is the
same address as selected via the DIP switches on the rear of the chassis. Add the HUB
address if one is used. At the very bottom of this set up window is a box labeled Bus
Message (Hex) It is here that you will enter the hex message to which you want the Event
Scheduler to respond. You must enter C0 prior to all inbound Hex messages to indicate to
NexSys that this will be treated as a program patch change. After you enter the Hex string
and close this window make the appropriate snapshot selection from D0. Complete the
remaining selections and select OK.
For outbound messages select Send Midi Message from D0. Enter the bus address of the
MIDI interface as required. Note that there is an additional selection for Port. The MIDI
interface has two output ports for sending messages; each port supporting 16 MIDI chan-
nels. Select the port to which you have made the physical connection to the receiving MIDI
Device- (NexSys Midi Interface to receiving MIDI unit). Finally enter your Hex message as
you want it sent.
13.4 MIDI HEX Programming
The NexSys MIDI interface is designed for two way communications to the data bus.
Outbound program patch changes are issued directly from the NexSys software as refer-
enced above. Provided you have properly configured the NexSys software all you need do
is select a target Device, a patch number and execute.
Inbound MIDI patch changes are handled differently from outbound patch changes. All
inbound patch changes are received in HEX notation by the MIDI Interface and are passed
on to the Event Scheduler. The Event Scheduler associates the received HEX message
(Event Scheduler trigger) with a pre-defined action and then executes it. If an inbound mes-
sage is received and it can not be associated with any action the Event Scheduler will disre-
gard it.
