Sampling mode
tempo-based LFO or delay effects, which can be very
useful when sampling rhythmic loops.
• Sampling can be initiated by the SAMPLING START/
STOP switch, note-on, threshold, or the SEQUENCER
START/STOP switch. (The available methods will
depend on the mode.) Threshold allows you to initiate
sampling when the input signal exceeds the threshold
level you specify. In Sampling mode, you can also
specify a pre-trigger setting.
• The analog audio inputs support mic and line level
signals. Digital audio input via S/P DIF IN supports the
48 kHz sample rate.
• You can digitally sample ("rip") audio data from an
audio CD in a CD-R/RW drive connected to the USB A
connector.
• Sampled data can be converted automatically (or
manually, using an easy operation) into a program. Once
a multisample/sample has been converted into a
program, you can make filter, amp, and effect settings
and play it as a program. Such a program can also be
used in Combination mode or Sequencer mode.
• Individual samples can also be used in drum kits.
When you turn off the power, all multisample and
sample data in RAM memory will be lost. Before you
turn off the power, be sure to save important data to
USB storage device. When the M3 is turned on, the
RAM memory will contain no multisamples or
samples, so you will first need to load previously-saved
data into RAM before you can edit it or play it back.
If Auto Optimize RAM (Global 0–2a) is on, and the
writing destination for sampling data is RAM, the RAM
memory will automatically be optimized after the data
has been written. This is turned on by default, but you
may switch it on/off as necessary. For more
information, please see "Auto Optimize RAM" on
page 359, and "Optimize RAM" on page 334.
Editing in Sampling mode
• In Sampling mode, the sample data you sampled or
loaded from various media (including WAVE and AIFF
formats) can be assigned to an index (zone) to create a
multisample.
• The waveform can be viewed in the display, and edited
by a variety of waveform editing commands that include
rate convert (down-sampling) and reverse playback.
• Start, loop start, and end addresses can be specified in
units of a single sample. Loop tune, reverse playback,
and loop lock functions are also supported.
• The Use Zero function automatically searches for zero-
cross points, making it easy to find the beginning or end
of the waveform, or locations that will not produce noise
when the sample is played back.
• The grid function displays a BPM-based grid on the
waveform display, helping you to create loops or make
waveform edits that match the desired BPM. At this
time, you can set the BPM value by pressing TAP
TEMPO in rhythm with the sample playback.
• Each multisample allows you to create up to 128 indices.
Each index consists of a sample assignment, a key zone,
an original key, a playback pitch, and settings such as
level.
• The Keyboard & Index display lets you edit a
multisample while viewing the assignments and zones
of each sample.
• Sample names and multisample names of up to 24
characters can be assigned. Sample names and
multisample names can also be viewed in Media mode
(see "Translation" on page 398).

• The Time Slice function automatically detects the attack
portions of a kick or snare etc. in a rhythm loop sample
(a looped pattern of drums etc.), and divides it into
separate rhythm instrument sounds. A pattern
corresponding to the divided samples is created
automatically, so that you can immediately use the
Sequencer mode RPPR function to play the pattern and
adjust the tempo without changing the pitch. You can
also do things such as adjusting the pitch of only the
snare, replacing it with a different sample, or changing
the playback timing on the sequencer, in this way
creating a new rhythm loop based on the rhythm loop
you started with. (Stereo samples are supported.)
• The Time Stretch function lets you modify the tempo
without changing the pitch of a sample. You can select
either Sustaining (suitable for sustain-type instruments
such as strings or vocals), or Slice (suitable for rhythm
loops on decay-type instruments such drums). Stereo
samples are supported.
• The Crossfade Loop function is an important looping
tool that helps smooth out irregularities in long loops
which contain complex material. By executing Crossfade
Loop, you can eliminate this problem and create natural-
sounding loops.
• The Link (with Crossfade) function allows you to join
two samples into a single sample. You can also crossfade
the overlapping portion of the samples at this time, so
that the volume changes gradually, producing a natural-
sounding transition.
• The BPM Adjust function (playback pitch adjust) lets
you adjust the playback pitch of each index so that the
loop frequency matches the desired BPM value.
• You can use resampling (auto) to automatically apply
effects to a sample and create a new sample.
• A multisample you create can easily be converted into a
program (Convert MS To Program (Convert
Multisample To Program)).
• In Sampling mode, the selected multisample or sample
will sound when you play the keyboard, allowing you to
hear the edited content of that page.
Sampling in Program, Combination, and Se-
quencer modes
• A performance in Program, Combination, or Sequencer
modes can be resampled internally, with all audio
remaining in digital form. This lets you resample a
performance that uses the M3's filters, effects, KARMA,
and sequencer etc.
• External audio sources from the various input jacks can
be sampled. A performance played on the M3 can be
mixed with the external audio source and sampled, or
you can sample just the external audio source while
monitoring the performance played on the M3.
• In Sequencer mode when you sample an external audio
source while listening to the playback of the song, note
data will be automatically created in the track. You can
use this In-Track Sampling function to sample vocals or
guitar while the sequencer is running.
• The song playback in Sequencer mode can be resampled
to a USB storage device (e.g., hard disk) connected to the
USB A connector. Then in Media mode you can edit the
song order and use a CD-R/RW drive connected to the
USB connector to create an audio CD.
