PROGRAM mode: HD-1
36
• A Wave Sequence uses twice as many voices as a
Multisample. A stereo Wave Sequence uses twice as
many voices as a mono Wave Sequence.
• Stereo Multisamples use twice as many voices as Mono
Multisamples.
• If the X-Y Envelope is enabled, the number of voices
used increases slightly.
Polyphony also depends on the effects being used, and on
which synthesis types are being used (HD-1, AL-1, CX-3
etc.). For more information, see “0–2: Performance Meter”
on page 13.
1–1c: Voice Assign Mode
Voice Assign Mode [Poly, Mono]
Select the basic voice allocation mode. Depending on which
one you select, various other options will appear, such as
Poly Legato (Poly mode only) and Unison (Mono mode
only).
Poly: The program will play polyphonically, allowing you
play chords.
Mono: The program will play monophonically, producing
only one note at a time.
Poly
Poly Legato [Off, On]
Poly Legato is available when the Voice Assign Mode is set
to Poly.
Legato means to play note so that they are smooth and
connected; the next note is played before the last note is
released. This is the opposite of playing detached.
On (checked): When you play a legato phrase, only the first
note of that phrase (and notes within 30 msec of the first
note) will use the normal multisample start point specified
by Start Offset (2–1c); all subsequent notes will use the
legato start point specified for each multisample.
Note: This is a useful way to simulate the percussive attack
of a tonewheel-type organ.
Off (unchecked): Notes will always use the setting of the
Start Point Offset, regardless of whether you play legato or
detached.
With some Multisamples, Poly Legato may not have any
effect.
Single Trigger [Off, On]
Single Trigger is available when the Voice Assign Mode is
set to Poly.
On (checked): When you play the same note repeatedly, the
previous note will be silenced before the next note is
sounded, so that the two do not overlap.
Off (unchecked): When you play the same note repeatedly,
the notes will overlap.
Mono
Mono Legato [Off, On]
This is available when the Voice Assign Mode is set to
Mono.
Legato means to play note so that they are smooth and
connected; the next note is played before the last note is
released. This is the opposite of playing detached.
When Mono Legato is On, the first note in a legato phrase
will sound normally, and then subsequent notes will have a
smoother sound, for more gentle transitions between the
notes.
The Mode parameter, below, switches between two different
Mono Legato effects, each of which achieves this
smoothness in a different way. See the description of that
parameter for more details.
On (checked): When you play with legato phrasing, the
notes within a legato phrase will sound smoother, according
to the setting of the Mode parameter, below.
Off (unchecked): Legato phrasing will produce the same
sound as detached playing.
Mode [Normal, Use Legato Offset]
This parameter is available only when Mono Legato is On.
Normal: When you play legato, the multisample, envelopes,
and LFOs will not be reset; only the pitch of the oscillator
will change. This setting is particularly effective for wind
instruments and analog synth sounds.
With this option, the pitch may occasionally be incorrect,
depending on which multisample you play, and where on
the keyboard you play.
Use Legato Offset: When you play legato, the second and
subsequent notes will use the legato start point specified for
each multisample, rather than the Start Offset (2–1c)
setting.
This is effective when used with a multisample for which
you’ve assigned a specific legato offset point. For example,
you might use it to control the attack of a breathy, slow-
attack sax sound. On some multisamples, this will have no
effect.
Envelopes and LFOs will still be reset, as they are with
detached playing.
Priority [Low, High, Last]
Priority is available when the Voice Assign Mode is set to
Mono.
This parameter determines what happens when more than
one note is being held down.
Low: The lowest note will sound. Many vintage,
monophonic analog synths work this way
High: The highest note will sound.
Last: The most recently played note will sound.
Max # of Notes
Max # of Notes [Dynamic, 1…16]
Dynamic is the default. With this setting, you can play as
many notes as the system allows.
1-16 lets you limit the maximum number of notes played by
the Program. Voices will still be allocated dynamically, up to
this maximum number. You can use this to:
• Model the voice-leading of vintage synthesizers, such as
the Polysix
• Control the resources required by individual Programs in
COMBINATION and SEQUENCER modes
