How Sample RAM Gets Jammed Up
Experimenting with Samples
To learn about sampling on the MV-8000, check out the following MV-8000
Workshop booklets: Sampling, Auto Chop, Importing a Sample from CD,
Direct Recording, Spreading a Sample Across the Pads.
The MV-8000 ships with a generous 128 MB of sample RAM,
and you can expand it all the way up to 512 MB—see the
MV-8000 Owner’s Manual for details.
To learn more about what sample RAM is, see the MV-8000 Sampling
Workshop booklet.
A similar thing can happen if you’re fooling around
with making samples. Even when you decide not
to use a sample, it’s still in sample RAM unless you
stop and delete it.
No matter how much RAM you have, you may find yourself in
a situation like this: you’re only using a few patches or audio
phrases in your project, but you find you’ve run out of room for
new patches or samples. Here’s how this can happen.
As with an unwanted patch, you can get rid of each of these
samples, one-by-one. You’d go to the MV-8000’s Sample
Manager in the PROJECT menu, select the sample, click
Command, and use the Delete option. Again, this can take
some time if you’ve got lots of samples to toss.
Hunting for the Right Patch
To learn how to load patches stored on your hard drive, see the
MV-8000 Loading Patches Workshop booklet.
Edited Copies
When you’re searching for the patches
you want to use in a project, each patch
you check out has to be loaded into
the MV-8000 before you can hear it.
When you do this, the patch’s samples
are loaded into sample RAM.
Destructive sample editing operations—such as
normalizing, truncating, and so on—offer you
the choice of replacing a sample with the edited
version, or of creating a new, edited copy. If you
make copies of samples during editing, you may
wind up with multiple versions of the same sample,
even though you’re only actually using one.
If you decide you don’t want to use a patch, and move on to
the next one you want to check out, the first patch’s samples
remain in sample RAM, taking up space. Try out a bunch of
patches, and you can see how lots of space in sample RAM
gets used up fast.
Wasted Notes
If you load an instrument that has lots of
samples running up and down the pads,
and you’re only playing a few notes, all
of its extra, unplayed samples tag along,
taking up space in sample RAM.
You can avoid this problem by manually deleting a patch along
with its samples after you’ve checked it out. (We describe how
to do this in detail in the MV-8000 Loading Patches Workshop
booklet.) Of course, it means stopping your patch search over
and over to take care of this housekeeping.

Sticky Stuff
How to Optimize a Project
Let’s say you start a project one day and
try out a lot of patches, or you make a
lot of samples you decide not to use.
Eventually, you find the sounds you want
and get down to business. At the end of
the day, you save your project.
1. Press PROJECT and select Sample Manager
from the PROJECT menu—this opens up the
SAMPLE MANAGER window.
Here’s the thing: when you save the project, all the unused
stuff gets saved, too. The next time you load the project, all
of this unwanted data gets loaded right alongside the good
stuff. Ba-boom! Suddenly you’re out of room for new patches
or samples.
The Solution: Optimization
2. Press the MENU button to display the Sample
Manager’s MENU pop-up.
The MV-8000 offers a special operation that trims away
everything in sample RAM that you’re not using. It’s called
“optimizing” a project.
Optimization removes:
•
•
•
•
samples that belong to patches you’re not using.
individual samples you’ve made that you’re not using.
unused copies of samples you’re using.
3. Select Optimize and click Select—the MV-8000 displays a
warning to remind you that anything in sample RAM that’s
not currently being used is about to get tossed out.
samples in patches for notes you’re not playing.
Optimizing can’t read your mind, so it doesn’t know if you intend to use
something in sample RAM that you’re not using yet. It searches for data
that’s not being used now, and deletes it. Therefore, don’t optimize your
project if you’ve got stuff in sample RAM you may want to use later on. (Of
course, you can always reload discarded patches from your hard drive later
on if you need to.)
4. Click Yes to proceed.
5. When optimization’s complete, save your project by
selecting Save Project from the PROJECT menu.
