NN-19 SAMPLER

143

NN-19 Synth Parameters

The NN-19 synth parameters are used to shape and modulate samples. These

are mostly similar to the parameters used to shape the oscillators in Subtractor -

you have envelope generators, a filter, velocity control etc. Again, it is important

to remember that these parameters do not alter the audio files in any way, only

the way they will play back.

! These parameters are global, in the sense that they will affect all

samples in a sample patch.

The Oscillator Section

For a sample patch, the actual samples are what oscillators are for a synthesizer,

the main sound source. The following settings can be made in the Osc section

of the NN-19:

Sample Start

This changes the start position of samples in a sample patch. Turning the knob

clockwise gradually offsets the samples’ start position, so that they will play

back from a position further “into” the samples’ waveform. This is useful mainly

for two things:

D Removing “air” or other unwanted artefacts from the start of less

than perfect samples.

Occasionally (although not in any samples supplied with Reason) you may

come across samples where the start point of the sample is slightly ahead of

the start of the actual sound. There may be noise or silence in the beginning

which was not intended to be part of the sample. By adjusting the sample

start position, this can be removed.

D Changing the start point as an effect.

For example, if you had a sample of someone saying “one, two, three”, you

could change the start position so that when you played the sample it would

start on “three”.

✪ You can also assign velocity sample start allowing to use your play-

ing to determine the exact sample start. See later in this chapter.

Setting Sample Pitch - Octave/Semitone/Fine

By adjusting the corresponding knobs you can change the pitch of all samples

belonging to a patch, in three ways:

D Octave steps

The range is 0 - 8. The default setting is 4.

D Semitone steps

Allows you to raise the frequency in 12 semitone steps (1 octave).

D Fine steps (100th of a semitone)

The range is -50 to 50 (down or up half a semitone).

! Note that the controls in this section cannot be used to tune sam-

ples against each other, as all samples will be affected equally. To

tune individual samples, you use the Tune parameter below the

keyboard display (see page 140).

Keyboard Tracking

The Osc section has a button named “Kbd. Track”. If this is switched off, the

sample’s pitch will remain constant, regardless of any incoming note pitch mes-

sages, although the oscillator still reacts to note on/off messages. This could be

useful if you are using non-pitched samples, like drums for example. You could

then play a sample in a zone using several keys, allowing for faster note trigger-

ing if you wanted to play a drum roll, for example.

Osc Envelope Amount

This parameter determines to what degree the overall pitch of the samples will

be affected by the Filter Envelope (see page 145). You can set negative or pos-

itive values here, which determines whether an envelope parameter should raise

or lower the pitch.
