Part 3 Yamaha Samplers — Professional Samplers A4000/5000
◊ Samples ◊ Sample Banks ◊ Programs
Sample parameters for up to six sets of samples can be
controlled in real-time using MIDI Control Change or
other control methods. Settings are simple and easy—
just set Device (what will be used to do the controlling),
Function (what it is to be controlled), Range (how much
control), and Type (how it will be controlled). Device
can specify Aftertouch, Pitch Bend, Note Number,
Velocity, Program LFO, and Key On Random, in addition
to MIDI Control Change numbers. The LFO explained in
the previous section (F5) cannot be synchronized to the
tempo of an external sequencer, but the A3000 ver. 2,
A4000 and A5000 all have a Program LFO that works as
a control signal generator to enable synchronization
with an external MIDI clock. By selecting Program LFO
as the Device, you can sync the sample’s control
parameters to the tempo of an external sequencer.
Sample Banks
There is an additional sample configuration called a
“sample bank.” A sample bank organizes a number of
samples into a single group and is convenient when
assembling a number of samples made by multi-
sampling or when putting together a drum kit.
This feature makes it possible to handle a number of
samples as if they were a single sample (Figure 18).
Sample banks allow you to edit sample parameters in
almost the same way as for individual samples.
For each parameter, you can select whether to make
settings individually for each sample or common to all
samples in the bank. For example, it would probably be
better to set common parameters for instruments such
as a piano, but to creatively use individual sample
parameters for drum kits.
Programs
Programs are used to play the A4000/5000’s samples
through a keyboard or other MIDI controller. Thus, a
MIDI controller cannot play any samples from the
A4000/5000 unless a program has been set up to use
them. (Up to 128 programs are available.)
Program parameters set the sound levels, transpositions,
etc. for all the samples within a program. Programs also
include Program LFOs, MIDI control for program
parameters, A/D input, effects common to all samples,
and an EASY EDIT function for the samples used in a
program.
Setting parameters is done in PLAY mode. PLAY mode
covers various functions, including F1: PROGRAM; F2:
SAMPLE; F3: EASY EDIT; F4: EFFECT; F5: SETUP and F6:
CONTROL, all of which are explained below.
F1: PROGRAM
This function selects and plays programs. It is used to
set the program mode*, the basic MIDI receive channel,
levels for all programs, transpositions, and portamento
common to the programs.
*Program mode selection (selecting Single or Multi).
In Single mode, only the selected program generates sound.
In Multi mode, you can freely assign any of the programs
(1 to 128) to each of the 16 multi parts (A4000) or 32 multi parts
(A5000). This is similar to using a multi-timbral synthesizer to
generate multiple voice parts simultaneously.
Caution:
When Multi is selected, tones are generated according to the
receive channel of each part rather than the MIDI receive channel
assigned to the individual programs and samples (Figure 19).
In this case, settings common to all samples such as effects,
Program LFO, etc. will use the master program (the program of
the part assigned to the basic receive channel).
F2: SAMPLE
This function assigns sample programs, sets sample
names, duplicates/deletes samples, and creates sample
banks.
● Assigning samples and sample banks
Example: Setting samples (or sample banks) to generate
tones under program control (Figure 20).
● Selecting programs
1) In PLAY mode, push the [F1] function key.
The PLAY-PgmSel screen will appear.
2) Select the program by rotating Knob 3 (or Knob 2).
● Selecting samples
3) Push the [F2] function key. The PLAY-SmpSel screen
will appear.
4) Select the sample (or sample bank) by rotating Knob
2. Set the MIDI receive channel for the sample by
rotating Knob 4 (=Smp, 1 to 16, Bch) to assign the
program.
Notes:
1) When a MIDI receive channel is set to =Smp, the receive
channel settings will be effective for the sample. For example,
if you want to use MIDI receive channels that you have set for
each sample parameter in a drum kit grouped in a sample
bank, you should select =Smp. The MIDI receive channel for
the sample can also be set in this manner using individual
sample parameters, and can be reset when assigning samples
to programs. It is better to make the settings in the easiest
way possible. When Bch is set, sound will be produced using
the same MIDI channel as Basic Rch on the PLAY-PgmSel
screen.
2) The A5000 is a 32 part multitimbral synthesizer, and thus the
receive channel can be set to A1–A16 (MIDI IN-A1 to A16),
=Smp, B1–B16 (MIDI IN-B1 to B16), or Bch.
3) When you don’t want a sample already assigned to a program
to play back, set the MIDI receive channel setting to “off” to
disassociate that sample from the program.
● Editing sample banks
The PLAY-SmpBank screen is used to edit sample
banks. The sample bank list is displayed on the left side
of the screen, and the sample list is displayed on the
right side of the screen (Figure 21).
In the sample list, samples are marked with symbols
“➞”, “ ”, and “USED” to indicate the status of the
samples.
“➞” indicates samples in the sample bank that have
been selected from the sample bank list on the left side
of the screen.
“USED” indicates a sample used in one or more of the
programs or in a sample bank.
