127
•
As
you've
already
seen,
you
can
select
128
different sounds using
Program Change messages.
Variation Select allows you to select any
of
128
variations
of
each Program Change message. An
illustration showing the relationship
of
Variation
Select messages to Program Change messages is
shown.
Variation messages have a value between 0 and
127.
If
you send a Variation Select message
of
8,
then Variation 8 will
be selected.
If
no
Variation
Select
message
is
sent,
then
Variation 0 (no variation) is assumed. Variation 0
was
shown
in
the
previous
diagram
with
no
shading.
Let's look at a specific example which will show
the relationship
of
Variation Select messages and
Program Change messages.
