Program P2: OSC/Pitch 2–1: OSC1 Basic
49
KeyOff is a special setting. Instead of delaying the
sound by a particular amount of time, the sound will
play as soon as you release the key. You can use this to
create the “click” heard when a harpsichord note is
released, for instance.
In general, when you use the KeyOff setting, it’s also
best to set the oscillator’s Amp EG Sustain Level to 0.
Mode [Key, Key + Damper]
Normally, you play notes simply by pressing keys on
the keyboard. In special cases, however, you can set
this parameter so that you must first be holding down
the damper pedal, and then press a key, in order to
play a note. For instance, this can be useful when
modeling the behavior of a piano soundboard.
Key is the normal mode.
When you select Key + Damper, notes will only sound
if the damper pedal is being held down. When the
damper pedal is released, all notes will be stopped–
even if they are still being held down.
2–1c: OSC1 Multisample/Wave Sequence
The parameters in this section will change depending
on the setting of the Oscillator Mode parameter.
In Single and Double modes, each Oscillator can play
up to four Multisamples or Wave Sequences. In Drum
mode, there is one Oscillator, and it plays a single
Drum Kit.
Multisamples, Wave Sequences, and Drum Kits
Multisamples, Drum Kits, and Wave Sequences allow
you to play samples in different ways.
• Multisamples lay out one or more samples across
the keyboard. For instance, a very simple guitar
Multisample might have six samples–one for each
string.
• Wave Sequences play back a series of different
Multisamples over time. These Multisamples may
crossfade to create smooth, evolving timbres, or
change abruptly to create rhythms.
• As the name suggests, Drum Kits are optimized for
playing drum samples.
Velocity splits, crossfades, and layers
As mentioned above, unless you’re in Drum mode,
each Oscillator has four velocity zones, named MS1
(High) through MS4 (Low). Each of these zones can
play either a Multisample or a Wave Sequence, and has
separate settings for Level, Start Offset, and so on.
Each of the zones can fade into the next, to create
smoother velocity transitions. Zones can even be
layered together, two at a time.
MS1 (High)
These are the settings for the first and highest velocity
zone.
If you want to create a simple setup with only a single
Multisample or Wave Sequence, just set up MS1 as
desired, and then set the Bottom Velocity to 1 and the
Xfade Range to 0.
Type [Off, Multisample, Wave Sequence]
This selects whether MS1 will play a Multisample, a
Wave Sequence, or nothing at all.
The Type selection affects the choices shown in the
Bank and Multisample menus.
Bank (Multisample) [ROM Mono…EXs Stereo]
This menu will appear only if the Type is set to
Multisample.
There are three main types of Banks: ROM, RAM, and
EXs. For each type, you can also choose between
looking at mono and stereo Multisamples. Note that
stereo Multisamples will require twice as many voices
as mono Multisamples.
ROM Multisamples are the built-in “factory” sounds,
and are always available.
RAM Multisamples include Akai, AIFF or WAV files
loaded from disk, and samples created in Sampling
mode.
EXs Multisample banks are PCM expansion sets
created especially for the OASYS. Each has its own
unique number; for instance, the ROM Expansion is
EXs1, and the Concert Grand Piano expansion is EXs2.
Only the currently loaded EXs banks will appear on
this menu.
Bank (Wave Sequence) [INT, U-A…G]
This menu will appear if the Type is set to Wave
Sequence.
INT Wave Sequences are the built-in “factory” sounds.
You can over-write them if you wish, but doing so may
change the sounds of the Programs and Combis in
Banks INT A–E.
U–A through U–G are user banks, for storing sounds
that you create yourself, optional sound banks from
Korg, or third-party sound libraries.
Multisample/Wave Sequence Select [List]
This parameter lets you select a Multisample or Wave
Sequence, depending on the Type setting.
Some Multisamples may have an upper limit to
their keyboard range, over which they may not
produce any sound.
To select a Multisample or Wave Sequence:
1. Press the Multisample/Wave Sequence Select
popup button to open the menu.
Within the window, ROM Multisamples are organized
by categories; Wave Sequences are organized by bank;
and EXs and RAM Multisamples appear as a
continuous list.
2. For ROM Multisamples or Wave Sequences, use
the tabs to select a category or bank.
3. Select a Multisample or Wave Sequence from the
list.
4. Press the OK button to confirm your selection, or
press the Cancel button to exit without making a
change.
