Detailed Editing with HD-1 Programs
55
Overview of editing pages
P0: Play is where you select and play programs, make
quick edits using the Control Surface, and adjust the
KARMA settings. The other pages let you modify the
sound in more detailed ways.
For details on how to access each mode and page, refer
to “Basic operations” on page 34.
The page and parameter structures of EXi Bank
programs are different than those of HD-1 Bank
programs.
Basic HD-1 Structure
Multisamples and Wave Sequences
The sound of the HD-1 starts with one or more
Multisamples. These can be recordings of instruments
like piano, bass, guitar, strings, organs, analog synths,
and so on, or purely digitally-created timbres.
You can use these Multisamples directly, or use them
through Wave Sequences, which play a series of
different Multisamples over time to create rhythms or
complex, evolving timbres.
Oscillator Mode
HD-1 Single Programs have one oscillator, and Double
Programs have two oscillators. Each oscillator includes
a complete synthesis voice, with velocity-switched
Multisamples, dual filters, EGs, LFOs, and so on.
Drums mode is a special variation of Single mode, and
uses a Drum Kit (as created in Global mode) instead of
Multisamples.
Single Programs use one oscillator, for a maximum of
172-note polyphony.
Double Programs use two oscillators, for a maximum
of 84-note polyphony.
Drum Programs use one oscillator to play a Drum Kit.
These will normally have a maximum of 172-note
polyphony.
A note about polyphony
Polyphony means the number of notes that you can
play at a time. This number will vary depending on the
particular sound being played, and how that sound is
produced. Generally speaking:
• Double Programs use twice as many voices as
Single Programs.
• Wave Sequences use twice as many voices as
Multisamples.
• Stereo Multisamples use twice as many voices as
Mono Multisamples, and Stereo Wave Sequences
use twice as many voices as Mono Wave Sequences.
• If the Vector EG is enabled, the number of voices
used increases slightly.
Voice Assign Mode
The Voice Assign Mode selects whether the Program
will play polyphonically (Poly) or monophonically
(Mono).
When this is set to Poly, you can play both chords and
melody lines. When this is set to Mono, only one note
will sound even if you play a chord.
Normally you’ll set this to Poly, but Mono is useful
when playing sounds such as synth basses, synth
leads, and other solo instruments. Try switching
between Poly and Mono, and listen to the results.
Using Drum Kits
You can create and edit Drum Kits in Global mode. For
each note on the keyboard, you can select up to four
velocity-crossfaded drum samples, make filter and
amp settings, and specify routing to the effects and to
the individual audio outputs.
For more information, see “Using Drum Kits” on
page 159.
In Programs, once you’ve set the Oscillator Mode to
Drums, you can select between the 144 user-
programmable Drum Kits, plus an additional 9 GM2
kits. For more information on the factory sounds, see
the Voice Name List.
Copying settings between OSC1 & OSC2
Many of the Program parameters can be set differently
for OSC1 and OSC2. These include all of the
parameters on:
• All of the tabs on the OSC/Pitch page, except for
the Pitch EG
• All of the tabs on the Filter page
