2. SYSTEM MESSAGES

System messages are the data related to the overall system
of the device.

System Exclusive Messages

System Exclusive messages control various functions of the
AN1x, including master volume and master tuning, effect
type and various other parameters.
Master Volume
When received, the Volume MSB will be effective for
the System Parameter.
F0 7F 7F 04 01 ll mm F7 (Hexadecimal)
* mm(MSB) = appropriate volume value, ll(LSB) =
ignored
Active Sensing
Once FE (Active Sensing) has been received, if no MIDI
data is subsequently received for longer than an interval of
approximately 300msec, the AN1x will perform the same
function as when All Sounds Off, All Notes Off, and Reset
All Controllers messages are received, and will then return
to a status in which FE is not monitored.
Refer to the MIDI Data Format in the separate Data List
book for more information about the various messages.
Control Change Modes
The AN1x has two Control Change modes. Mode 1
corresponds to the list of Control Change parameters
according to the MIDI standard. Mode 2 is a special list of
Control Change parameters unique to the AN1x.
For information about changing modes, see page 96. For a
list of Control Change parameters for each mode, see the
separate Data List book.
