NN-XT SAMPLER

271

Tuning Samples Manually

In addition to setting the root note, you may need to fine tune your samples, in order

for them to match other instruments and/or each other:

D Make sure the zone has edit focus (for example by clicking on it).

D Use the knob marked “Tune” in the sample parameter area.

This allows you to tune each sample in a key map by +/– half a semitone

(-50 – 0 – 50).

Setting the Root Note and Tuning Using Pitch

Detection

The NN-XT features a pitch detection function to help you set the root keys. This is

useful if you for example load a sample that you haven’t recorded yourself, and you

don’t have any information about its original pitch.

Proceed as follows:

1. Select all the zones you want to be subject to pitch detection.

2. Pull down the Edit menu or the NN-XT context menu and select “Set Root

Notes from Pitch Detection”.

The samples in all the selected zones will now be analyzed, and the detected root

keys will automatically be set for you.

! Note that for this to work properly, the samples must have some form of

perceivable pitch. If it is sampled speech, or a snare drum for example, it

probably doesn’t have any discernible pitch.

About Changing the Pitch of Samples

The procedures above should be used to make sure the samples are consistently

pitched across the keyboard, and that they all match an absolute reference (for exam-

ple A 440 tuning).

If you need to tune the samples to match other material, or to get a certain effect (for

example detuning two sounds against each other for a chorus effect) you should use

the Pitch section among the synth parameters, not the sample tuning parameters.

Using Automap

The automap function can be used as a quick way of creating a key map, or as a good

starting point for further adjustments of a key map.

Automap works under the assumption that you intend to create a key map for a com-

plete instrument, for example a number of samples of a piano, all at different pitches.

1. Load the samples you want to Automap.

Now you have three options:

D Trust that the root note information in the files is already correct.

D Manually adjust the root notes (and tuning) for all the samples.

D Use “Set Root Notes from Pitch Detection” to automatically set up the

root notes.

2. Select all zones you want to automap.

3. Select Automap Zones from the Edit menu or the NN-XT context menu.

All the selected zones will now be arranged automatically in the following way:

D The zones will be sorted in the display (from top to bottom - lowest key

first) according to the root keys.

D The zones will be assigned key ranges according to the root keys.

The key ranges are set up so that the split between two zones is exactly in the mid-

dle between the zones’ root notes. If two zones have the same root key they will be

assigned the same key range.

Automapping zones chromatically

D This Edit menu item will give each zone a key range of one semitone (i.e.

one key), starting from C2 and upwards.

The function does not take root key into account. It simply places each selected

sample on successive keys according the position in the sample list (from the top

down).
