Edits will always be accurate over the entire range of
the sampler unless you change direction (cross the 0
boundary) after triggering. There is, therefore, no limi-
tation on auditioning a tight edit at low speed and
playing it back fast – just avoid changing direction while
playing. Changing direction will cause minor inaccura-
cies in the play time.
From Version 3.00 on, the SME samplers have a third
FADE TYPE called SCRUB MODE, for those applica-
tions where play time is less important than the fun you
can have moving the RATE slider around. In SCRUB
MODE there is no fade out, ever. The sample starts at
the HEAD time, then plays continuously through
memory and around again.
To disable SCRUB MODE, adjust FADE TYPE to
PERCUSSION or FAST FADE UP and press CUE.
Using MIDI to Control a Sampler
®
Dynamic MIDI is very helpful when used with the
sampling programs. MIDI controllers can be patched to
control sampler parameters such as HEAD TRIM,
FWD TIME, and FADE TYPE. MIDI Note On events
can be patched to control sampler events, such as
RECORD, CHECK, PLAY, etc.
A single note can be patched to trigger an event, or a
range of notes can control a single event. The following
procedure assumes you have made MIDI connections
and set the 480L's MIDI channels (as described in
MIDI and the 480L).
Note: Because of different processing times for
events and parameters in the 480L, you should be
careful patching parameters to note event data (LST
NOTE, LAST VEL) when the note event is triggering
a 480L sampling event like PLAY. The parameter will
usually not be updated until after play starts, so the
parameter updates will be missed unless the same
event is repeated.
In the rate-changing samplers, a special event (MIDI
PLAY) has been created that directly updates the rate
parameter before play starts. This allows triggering
samples from a MIDI keyboard at rates that correspond
to the MIDI semitone pitch intervals. On the same
LARC page are two parameters that control the MIDI
PLAY interaction with RATE, Reference MIDI Note,
and Pitch MIrror. They are fully described in the next
section.
Bank 7: the Sampler Programs
Typically, two patches are needed to control a sampler,
assuming that you will handle recording and preliminary
editing manually. You will need to patch MIDI source
"NOTE EVENT" (over some range of note values) to a
480L sampler "event" (usually a PLAY key) so that
playing a synthesizer key will trigger the edited sample.
Having done this, there are several interesting parame-
ters you can vary, including FORWARD TIME (TAIL
TRIM in the SME), REPEATS, and RATE. These may
be patched to MIDI sources such as PITCH WL, MOD
WL and other controllers.
To patch a MIDI controller to a sampler parameter:
1. Press CTRL to enter Control Mode. Go to page 4.
2. Use SEL to select the patch to create (there are 10
possible patches).
3. Use SRC to select the MIDI controller for the
patch.
4. Use DST to select the parameter you will control.
5. Use SCL to set the scaling of the MIDI controller to
the sampler parameter.
6. Use PRM to set the base setting for the parameter,
and audition the effect of the controller.
7. After setting up your patches, be sure to save the
new settings in a register.
To patch a MIDI note event to trigger a sampler event:
1. Press CTRL to enter Control Mode. Go to page 4.
2. Use SEL to select the patch to create (only the first
four patches can be used for events).
3. Push the SOURCE slider all the way up to NOTE
EVENT.
4. Use DST to select the event you wish to control.
5. If you want to use a single key to trigger an event,
set LOW NOTE and HIGH NOTE to the same
value.
6. If you want a range of keys to trigger an event, use
LOW NOTE to set the low end of the range, and
HIGH NOTE to set the high end of the range.
7. After setting up your patches, be sure to store the
new settings in a register.
When using MIDI to control the sampler, be careful not
to send the 480L a program change command. This will
load a new program or register, resulting in the loss of
the sample in memory. To prevent this from happening,
the PGM CHANGE parameter in the control mode can
be set to IGNORE. This causes the 480L to ignore MIDI
program changes.
