System Messages - Yamaha MO6 Owner's Manual

About MIDI
Pitch Bend
Pitch Bend messages are continuous controller messages
that allow the pitch of designated notes to be raised or
lowered by a specified amount over a specified duration.
Channel Aftertouch
Messages which let you control the sounds by the pressure
you apply to the keys after the initial striking of the keys,
over the entire channel.
This synthesizer does not transmit this data from the
keyboard; however, this synthesizer does properly respond
to this data when received from an external device.
Polyphonic Aftertouch
Messages which let you control the sounds by the pressure
you apply to the keys after the initial striking of the keys, for
each individual key. This synthesizer does not transmit this
data from the keyboard; however, the data is transmitted
from the internal sequencer.

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
this synthesizer, including master volume and master
tuning, tone generator mode, effect type and various other
parameters.
General MIDI (GM) System On (Song mode/Pattern
only)
When "General MIDI system on" is received, the MO will
receive the MIDI messages which are compatible with GM
System Level 1, and consequently will not receive NRPN
and Bank Select messages.
F0 7E 7F 09 01 F7 (Hexadecimal)
n
Make sure that the interval between this message and the first note
data of the song is at least a quarter note or greater in length.
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
System Realtime Messages
These messages control the sequencer, that is to say Song
and Pattern.
Active Sensing (FEH)
Once FEH (Active Sensing) has been received, if no MIDI
data is subsequently received for longer than an interval of
approximately 300 msec, the MO 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 FEH is not monitored.
Owner's Manual
226
Timing Clock (F8H)
This message is transmitted with a fixed interval (24 times
per 1/4 note) to synchronize connected MIDI instruments.
You can select whether the sequencer block uses the
internal Timing Clock, or external Timing Clock messages
received via MIDI IN by setting the MIDI Sync parameter:
[UTILITY] [F5] MIDI [SF3] SYNC
Start (FAH)
This message lets the MIDI sequence data start playing
back from the beginning. This message will be transmitted
when pressing the [F] (Play) button at the top of the Song
or Pattern.
Continue (FBH)
This message lets the MIDI sequence data start playing
back from the current song position. This message will be
transmitted when pressing the [F] (Play) button at the
middle of the Song or Pattern.
Stop (FCH)
This message causes MIDI sequence data (song) to stop
playing back. This message will be transmitted when
pressing the [ ] (Stop) button during playback.
n
You can select whether this synthesizer will transmit Timing Clock,
Start, Continue, and Stop messages by setting the SeqCtrl
parameter: [UTILITY] [F5] MIDI
System Common Message
System Common messages also control the sequencer,
including Song Select and Song Position Pointer messages.
