Velocity Messages
These messages are the 'notes' that are sent from equipment
such as keyboards and synthesizers. The GT-3 is unable to
use these messages but they can be used by the GT-5 to
trigger the internal pedal as part of a control assign. We will
examine the use of these messages when we look at
configuration.

Pitch Bend Messages
These messages are the sent from equipment such as
keyboards and synthesizers. The GT-3 is unable to use these
messages but they can be used by the GT-5 to trigger the
internal pedal as part of a control assign. We will examine
the use of these messages when we look at configuration.
SYSEX Messages
System Exclusive ("Sysex" for short) Messages are used to
transfer device specific data. They can be used to control
the device in a fuller implementation outside the normal
ability of MIDI and they are also used for 'dumps' and
'bulk loads'. These dump and bulk loads are effectively the
backup & restore. Most MIDI units provide at least these
facilities.
The GT-3 & GT-5 have full implementations and the patch
editors that are available for these two units takes advantage
of these messages to alter ALL of the set-up. That means
from a PC you can control the on/off of an effect change the
type of effect and even change any of the parameters of any
effect real-time! You can even change the global settings!!
On a PC, patches are often backed up into '.syx' files.
These '.syx' files contain the Sysex information for the
patch. A single '.syx' file may contain everything from a
single patch to multiple patches to an entire backup of a
unit.
Because of the device specific nature of the Sysex
messages, the GT-3 & GT-5 are as such incompatible. This
means you cannot feed GT-3 patches into a GT-5 using
SYSEX and vice versa. If you try you may achieve some
changes, but whilst it won't damage your unit you may find
the need to re-configure. At best part of the patch
information will have been transferred.
There is obviously much more that we could go into, but the
details behind Sysex Messages are just so involved. To go
too deeply into these details would likely cause unnecessary
confusion.
