NN-XT Sampler : Managing Zones and Samples

Managing Zones and Samples
Creating a Key Map
When you add an NN-XT sampler to the rack and select “Reset Device” from the context menu or Edit menu, its key map display becomes empty. That is, it contains no samples.
To create a new key map, proceed as follows:
1.
The NN-XT device gets browse focus.
The Browse Samples button.
2.
The selected sample(s) are loaded into the NN-XT.
*
The panel is dimmed in blue and a Sample Replace symbol appears in the center.
When new samples are loaded into the NN-XT they have the following properties:
A key map with four newly added samples.
Setting Root Notes and Key Ranges
The next step after loading the samples is most likely to adjust the key range, root note and tuning of the samples, so that they play sensibly across the key range. There are many ways of doing this, described in “Working with Key Ranges” and onwards. However, we will here briefly describe a procedure for quickly creating a complete key map out of a set of loaded samples.
This example assumes that the samples you load is a set of multisamples for a pitched instrument (like guitar, piano, flute etc.).

All selected zones are automatically arranged into a basic key map. You can now proceed with adjusting the synth parameters on the front panel to shape the sound!
About file formats and REX slices
The audio file format support differs depending on which computer OS you are using.
The NN-XT can read audio files in the following formats:
.wav, .aif, .mp3, .aac, .m4a and .wma.
.wav, .aiff, .3g2, .3gp, .mp1, .mp2, .mp3, .mpeg, .mpa, .snd, .au, .sd2, .ac3, .aac, .adts, .amr, .caf, .m4a .m4r and .mp4.
This is a standardized data format containing wavetable synthesized audio and information on how it should be played back in wavetable synthesizers - typically on audio cards. SoundFont banks are hierarchically organized into different categories: User Samples, Instruments, Presets etc. The NN-XT lets you load single samples from within a Soundfont bank.
A slice is a snippet of sound in a REX File (see “Loading complete REX files as Patches”). To import a REX slice, browse to a REX file and open it as if it was a folder. The browser will then display the slices as files inside that “folder”. In the rest of this manual, when we refer to importing samples, all that is said applies to REX slices as well.
Adding more samples to the Key Map
You can add additional samples to an existing key map way described above.
1.
If you don’t, there’s a risk that the selected sample will be replaced, see below. To remove the edit focus, click in an unoccupied area in the Sample column or the key map area.

The panel is dimmed in blue and a Sample Replace symbol appears in the center.
The new sample(s) are added to the key map.
Replacing a sample
To replace the sample in a zone, proceed as follows:
1.
*
*
*
Any of these methods will set browse focus and open the standard file browser in which you can select new samples for the zone.
2.
If you select more than one sample in the browser the samples you load will not replace the one with edit focus. They will instead be added below it.

The panel is dimmed in blue and a Sample Replace symbol appears in the center.
Quick browsing through samples
If you want to quickly browse through a number of samples, for example to see which one of them would fit best in a certain context, proceed as follows:
1.
2.
Removing samples
*
This will remove the sample from the zone, leaving it empty. Note that you can remove the samples from several selected zones at the same time.
Auditioning samples
You can audition the loaded samples in two ways:
*
The mouse pointer will take on the shape of a speaker symbol when you move it over the sample column.
Clicking a sample will play it back at its root pitch (see “About the Root Key”). Furthermore, the sample will play back in its unprocessed state. That is, without any synth-parameters applied (see “Synth parameters”).
*
The difference here is that you will hear the sample at the pitch corresponding to the key you clicked and with any and all processing applied. The click mimics a key played with velocity 100. Also note that this may trigger several samples, depending on whether they are mapped across the same or overlapping key ranges, and the velocity range settings (see “Setting up Key Ranges” and “Setting velocity range for a Zone” respectively).
Adding empty Zones
You can add empty zones to a key map. Empty zones are treated just like zones containing samples, in that they are automatically selected, gets edit focus and are assigned a five octave key range when they are first created. However, you can only add one zone at a time. It is also possible to resize, move and edit empty zones in the same way as zones containing samples.
*
An empty zone is added below any existing zones in the key map. An empty zone is indicated with the text “**No Sample**”.
After you have added an empty zone, you can assign a sample to it, just as when Replacing a Sample, or when Quick Browsing, as described above.
Duplicating Zones
You can duplicate any number of already existing zones (containing samples or empty).
1.
2.
The selected zones will now be copied and automatically inserted below the last one in the key map display.
The duplicated zones will contain references to the same samples as the original zones. They will also have the exact same key ranges and parameter settings.
Using Copy and Paste
The Copy Zones function on the Edit menu allows you to copy all selected zones to the clipboard. Selecting Paste Zones from the Edit menu will paste the zones into the selected NN-XT device, below the existing zones.
This is a handy way to transfer zones (complete with all settings) from one NN-XT device to another.
Removing Zones
To remove one or several zones, select them and do one of the following:
*
*
When removing zones, you will remove any samples in them as well.
Rearranging Zones in the List
*
An outline shows you where the zone will appear when you release the mouse button.
