Auto Chop
How Auto Chop Works
You can Auto Chop a new sample, an already-existing audio phrase, or an
unused sample from the project SAMPLE folder.
ꢂ� Skip ahead to “Chop Shop” on Page 4.
Auto Chop analyzes a sample, looking for places it can slice its sounds into
separate samples, placing a “chop point” marker at each of these locations.
If you like the chop points Auto Chop finds, it slices up the sample for you. If
you don’t, you can change your Auto Chop settings and have it try again.
To Auto Chop an Existing Audio Phrase
ꢀ� Press AUDIO PHRASES to show the AUDIO
PHRASES (PAD) window, and play your audio
phrase.
For the pictures in this booklet, we’re working in a new, blank
project—things may look a little different in your project.
Using Auto Chop
When you strike a
pad, its E.Grp value
highlights in blue. We
hit Pad 1 here.
To Auto Chop a New Sample
To learn how to sample, see the MV-8800 Sampling Workshop booklet.
Once you’ve set the Start and End Point parameters in the RESULT
window—and checkmarked Truncate—you’re ready to use Auto Chop.
ꢁ� Press QUICK EDIT, and then click Chop.
ꢀ� In the RESULT window, click Quick Assign.
ꢁ� In the Select Quick Assign window, click Chop.

To Auto Chop an Unused Sample
Chop Shop
As noted in the MV-8800 Sampling Workshop booklet, you can sample
something and stash it away for later use without assigning it to a patch or
as an audio phrase right away. Samples like this simply go into their project’s
SAMPLE folder.
To grab one of these samples and Auto Chop it:
ꢀ� Go to the PROJECT menu and select Sample Manager—this opens the
Sample Manager window.
You can use the Chop window manually, placing your own chop points
by hand, but Auto Chop is usually much faster and easier.
ꢀ� Click Auto Chop—the AUTO CHOP pop-up appears.
ꢁ� Select the sample you’d like to chop.
ꢂ� Click Quick Assign to display the Select Quick Assign window.
The Chop Type parameter sets the method the MV-8800 uses for
analyzing the sample and placing chop points.
ꢁ� Set Chop Type to one of the following values. Choose:
•
Level—so Auto Chop places a chop point each time the sample’s
volume reaches a certain level. This is usually the method that
works best.
•
Beat—so Auto Chop divides the sample at each beat. If you’re
working with a loop generated by a drum machine, and its timing
is perfect, Beat may work well.
ꢃ� In the Select Quick Assign window, click Chop.
ꢄ� Proceed to the next section, “Chop Shop.”
During sampling or when you’re importing a loop, you can tell the
MV-8800 how many beats are in the sample so it knows where the beats
are now.

•
Divide X—so Auto Chop divides the sample into the desired
number of equal-size slices. In a way, this is similar to Beat, but may
work better for you if you’re not used to thinking in beats. Divide X
works well with drum-machine loops.
In the lower left-hand corner of the window, you can
see the pads that’ll play your slices—they’re pink. The
MV-8800 automatically uses as many pads as the sounds in your sample
require.
ꢄ� Play each slice’s pad to hear its sound and check out the suggested
chop point. As you strike a pad, its slice is selected and the display
shows its location in the sample.
ꢂ� For each Chop Type, there’s another parameter to set.
If your Chop Type is:
Set:
To:
ꢅ� If you like the chop points, proceed to Step 9.

1-6. A setting of 6 places chop
points at only the loudest spots
in the sample. To dig out quieter
sounds, try lower values.
ꢆ� If you like what you’ve got but want to make a small adjustment to any
slice, strike its pad to select the slice, and then adjust its Chop Point
parameter value.

the type of beat you want to use
for placing chop points.
The Chop Point location is shown as 12-digit number. You can
individually select and change any of its digits to move the chop point.
Change digits to the left to move the chop point by larger amounts, or
use digits to the right to move it by smaller amounts.

plays that patch.
Normally, you control the volume of a sample by how hard you hit
its pad. To automatically make your samples loud, light the FIXED
VELOCITY button above the pads. By default, this’ll make your sounds
play at full volume.
Once you add samples to an Init Patch, we strongly recommend you
name the patch—we’ll show you how to do this in a bit—to make sure
you can tell it apart from still-empty patches. If you don’t, things can
get really confusing when you need to find an empty patch later on.
Setting Up the Behavior of a Sample
The Assign To parameter allows you to change the pads that’ll play the
samples. If you’re:
Repeat the following process for each sample in the patch that needs
setting-up.
•
making a new patch for the samples—there’s no reason to change
the pads that are already selected unless you’d rather play the
samples from some other pads.
•
sending the samples into an already-existing patch—make sure
you’re putting the samples on pads that aren’t already in use.
Following the instructions in “Playing Your Patch” above, play a sample you
want to set up. Next, press the QUICK EDIT button to display the PARTIAL
EDIT window.
The CHOP QUICK ASSIGN window shows you any pads that are already
being used—they’re pink instead of white.
ꢀꢀ� Strike the first pad you want to use—the MV-8800 automatically
assigns the rest of your slices to the pads that follow it. The CHOP QUICK
ASSIGN window outlines the series of pads you’ve selected.
When you hit a pad now you won’t hear anything—the pads don’t play
your samples until you’ve finished assigning them in this window.
You can quickly jump the Assign To value to another pad bank by
pressing the PAD BANKS button, typing the desired bank’s number on the
MV-8800’s numeric keypad, and then pressing PAD BANKS again.
In this window, you set the behavior of the “partial” that plays the sample.
A partial is a group of up to four samples that are played together from
a pad or a range of pads.
ꢀꢁ� Click Execute.

Finger on the Trigger
You can also send related samples to the same Aux bus, allowing you
to change all of their volumes at once in the MIXER (AUX/FX/AUDIO
PHRASE/INPUT) window.
•
One Shot—Turn this parameter on so that the sample plays all the way
through when you strike its pad. This makes the pad act like a trigger:
Just hit it, and the sample plays without your having to hold down the
pad.
If you’ve installed an optional MP8-OP1 audio expansion board, you can
send the sample to a single output jack (Mlt1-8) or to a stereo pair of
output jacks (M1/2-7/8).
If you turn on One Shot and the sample still doesn’t play all the way
through, go down to the Amplifier R (for “Release”) parameter at the
bottom of the window and turn it all the way up.
•
•
DlyCho Send—sets the amount of delay or chorus you want to add.
Rev Send—sets the amount of reverb you want to add.
The How Loud and Where Settings
Playing Fast and Playing Rolls
•
Level—This parameter sets the volume of the partial that plays the
sample.
•
Assign Type—This parameter sets what happens when you play fast
notes or rolls. If you set it to:
•
Mult—the sample plays through each time you hit the pad. This
setting produces the most natural sound.
If you’ve got more than one sample in a patch, use this parameter to
set their volumes relative to each other, and set the sample you want
to be the loudest to 127.
•
Sngl—each time you hit the pad, it cuts off the previous note,
creating a more mechanical sound.
•
Pan—This sets the stereo location of the partial.
Me. No, Me.
If you’re working on a patch that contains drum kit sounds, you can pan
their individual partials to sound like a real-world drum kit.
•
Excl Group—If you assign two or more partials to the same exclusive
group, they cut off each others’ notes. In drum-kit patches, the open
and closed hi-hat partials are often set to the same exclusive group so
they can’t play at the same time, just like in the real world.
When you record with a patch, its track has its own Pan setting that
shifts the stereo position of all of the samples in the patch to the left
or right.
For Further Study
To learn about the window’s remaining advanced parameters and tools, see
the MV-8800 Owner’s Manual.
Cause of Effects
•
Output Assign—sets where the sample’s sound goes. You can select:
•
•
Mix—so the sample is sent into the main mix as it is.
Aux1-4—so the sample is sent to the Aux bus that’s feeding the
MFX (for “Multi-Effects”) effect processor. This allows you to add
MFX to the sample.

Naming and Saving Your Patch
The End
Now that you’ve made your patch, there’s a little housekeeping to do. As we
noted earlier, you should name your patch so you know it’s no longer empty,
and can easily identify it later. We also suggest you save it into your project
patch library.
Auto Chop is one of the MV-8800’s handiest tools, and we hope you’ve
found this workshop helpful. Keep an eye out for other MV-8800 Workshop
