NN-XT SAMPLER
182
The LFOs
NN-XT features two Low Frequency Oscillators - LFO 1 and LFO 2. “Normal”
oscillators generate a waveform and a frequency, and produce sound. Low fre-
quency Oscillators on the other hand, also generate a waveform and a fre-
quency, but there are two major differences:
• LFOs only generate sounds of a low frequency.
• LFOs don’t produce sound, but are instead used for modulating various pa-
rameters.
The most typical use of an LFO is to modulate the pitch of a sound (generated
by an oscillator or - in the case of NN-XT - a sample), to produce vibrato.
About the Difference between LFO 1 and LFO 2
There are two fundamental differences between LFO 1 and LFO 2:
D LFO 2 is always key synced, that is, each time you press a key, the
LFO waveform starts over from scratch. LFO 1 can be switched be-
tween key synced and non-key synced modes.
D LFO 2 only has one waveform, triangle.
The following parameters are available for the LFOs:
Rate (LFO 1 and 2)
This knob controls the frequency of the LFO. For a faster modulation rate, turn
the knob to the right.
The Rate knob of LFO 1 is also used for setting the timedivision when synchro-
nizing the LFO to the song tempo (see below).
Delay (LFO 1 and 2)
This can be used for setting a delay between when a note is played and when
the LFO modulation starts kicking in (gradually). This way, you can make the
sound start unmodulated, and then have the LFO modulation start after you have
kept the key(s) pressed down for a while.
Turn the knob to the right to increase the delay time.
Mode (LFO 1 only)
This lets you set the “operation mode” for the LFO. Click the button to switch
between the available modes:
D Group Rate
In this mode, the LFO will run at the rate set for it’s group in the group sec-
tion, rather than at the rate set here (see page 174). This way, all zones in
the group will have the exact same modulation rate.
D Tempo Sync
In this mode, the LFO will be synchronized to the song tempo, in one of 16
possible time divisions.
! When tempo sync is activated, the Rate knob is used for selecting
the desired timedivision. Turn the Rate knob and observe the tool
tip for an indication of the timedivision.
D Free Run
In free run mode, the LFO simply runs at the rate set with the Rate parame-
ter. Furthermore, if Key Sync is deactivated, the modulation cycle will not be
retriggered each time you press a key - it will run continuously.
