order, releasing the keys in reverse order (D C B A) will cause the next allocated voice to be
D. That is because it has been released the longest, so it has the best chance of having
completed the release cycle of its envelopes. If more notes are played than there are voices,
then only the first notes will sound, at least until one of those notes playing is released. At
that point, its voice will be reallocated to the next note in line. The
GATE
output will stay
high. If the
Velocity/Trigger Output
is set to
S-Trigger
, then the
VEL
output won’t
retrigger when the previously held note is sounded.
Poly
1
St
Poly 1 Steal
works like the
Poly 1
mode until all the voices are used and another note is
played. At that point, the new note will “steal” the voice of the first note played. If the
Velocity/Trigger Output
is set to
S-Trigger
, then it will retrigger when the voice is
stolen. If the first note is still held when the new note is released, its voice will be restored,
however, the
VEL
output won’t retrigger if set to
S-Trigger
.
Poly2
Poly 2
is a polyphonic allocation algorithm which always allocates the first voice in its
voice group first, the second voice second, and so on.
Poly 2
is useful for ensuring that
notes are assigned to voices in a predictable manner. This can be used with the
Glide
feature to make a super cool polyphonic portamento sound.
Poly 2
, like
Poly 1
, does
nothing when more notes are played than there are voices.
Poly2 St
Poly 2 Steal
works like the
Poly 2
mode until all the voices are used and another note is
played. At that point, the new note will “steal” the voice of the first note played, just like
Poly 1 Steal
mode.
Unison
Unison
is yet another polyphonic mode. The idea behind
Unison
is to make the fattest
sound possible, by assigning multiple voices to each note.
Unison
mode works like
Solo
Unison
for the first note played, in that it allocates all of the voices to playing the note.
Then things start getting strange. If two or more notes are being played, the voices are
divided between the notes played. For instance, if the
Voice Group Type
is
4
, then there
are 4 voices available. The first note played will use all 4 voices, the second note will steal
2 of those voices so that each note has 2 voices, the third note will steal one voice from the
first note and turn off one of the second note’s voices, the fourth note will play that turned
off note, and subsequent notes will be ignored until one of the first 4 notes are released. If
the
Voice Group Type
is
2/2
, then there are 2 voices available, so the first note will play
with 2 voices, the second note with one, and subsequent notes will be ignored, just as they
are with
Poly 1
and
Poly 2
.
