EXi: STR-1 Plucked String
242
These can change the character of the comb filter in
interesting ways.
Layering PCM with modeled string timbres
You can also simply layer PCM samples with string
timbres. To do so, set the Filter Routing to Parallel,
and then use the Mixer page to route the PCM
Oscillator to Filter A, and the String to Filter B (or vice-
versa). For more information, see “5-1a: Routing” on
page 261, and “4-9: Mixer” on page 259.
Creating an initialized STR-1 Program
For the examples above, it can be useful to start with
the default STR-1 settings. To do so:
1. In Program mode, select USER-F 000,
Felix’sDaKat.
2. Press the Common tab, and then the Basic/Vector
tab, to go to the Basic/Vector page (P4–4).
3. Under EXi Instrument Type, select STR-1 Plucked
String.
Now, you have an initialized STR-1 Program.
4–2a: Multisamples
This section selects the Multisamples to be used for the
string excitation.
Velocity splits
As mentioned above, each Oscillator has four velocity
zones, named MS1 (High) through MS4 (Low). Each of
these zones can play a different Multisample, and has
separate settings for Level, Start Offset, and so on.
Note that, unlike the HD-1, crossfades and layers are
not supported.
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, just set up MS1 as desired, and then set
the Bottom Velocity to 1.
Type [Off, Multisample]
This selects whether MS1 will play a Multisample, or
nothing at all. You can use this to disable any of the
four Multisamples.
Bank [ROM Mono…EXs Mono]
There are three main types of Banks: ROM, RAM, and
EXs.
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.
Note that unlike the HD-1, you can only select
mono Multisamples.
Multisample Select [List]
This parameter lets you select a Multisample for the
velocity zone. You can use any mono Multisample, or
the left or right channel of a stereo Multisample.
Some Multisamples may have an upper limit to
their keyboard range, over which they may not
produce any sound.
Multisample Select menu
To select a Multisample:
1. Press the Multisample Select popup button to
open the Multisample select menu.
2. Use the tabs to select a category and sub-category.
3. Select a Multisample from within that
category/sub-category.
4. Press the OK button to confirm your selection, or
press the Cancel button to exit without making a
change.
The list shows all of the mono Multisamples in the
Bank. If the Bank contains stereo multisamples, you’ll
also see the left and right channels as separate, mono
multisamples, with -L and -R appended to the end of
the name.
Reverse [Off, On]
This lets you play the selected multisample backwards,
without looping.
Note: If the individual samples within a Multisample
are already set to Reverse, they will still play in
reverse, regardless of this setting.
On (checked): The Multisample will play back in
reverse.
Off (unchecked): The Multisample will play back
normally.
Level [0…127]
This sets the basic volume level of the multisample.
Use this to adjust the balances between the four
velocity zones.
The Excitation Mixer, main Mixer, and Amp sections
can modify this basic level extensively with envelopes,
LFOs, keyboard tracking, and other modulation; for
more information, see “4-4: Excitation Mixer,” on
page 246, “4-9: Mixer,” on page 259, and “6-1: Amp,”
on page 269.
Depending on the multisample, high Level settings
may cause distortion when playing many notes at a
time. If this occurs, lower the Level.
With RAM Multisamples, each Sample also has a
“+12dB” option. If this is turned on, the Sample will
play back approximately 12dB louder. You can
configure this parameter for each Sample in Sampling
mode.
Start Offset [Off, 1st…8th]
In addition to simply starting playback from the
beginning, ROM and EXs Multisamples can have up to
8 different pre-programmed alternate starting points.
