LFOs

[Nitrox 1.11]

Nitrox comprises four independent LFOs (low frequency oscillators) for modulation purposes. The variety of parameters show their extreme flexibility:

To add even more flexibility, some of the LFO parameters can even be modulated themselves using one of the five separate modulation units. Here, not only the modulation sources can be configured but also the modulated parameter. Note, that one LFO can modulate the parameters of another one.

In contrast to ADSRs or envelopes the LFOs are not voice specific, i.e. they are synchronous for all currently played notes. Note, that envelopes can be configured to loop and, hence simulate an LFO which is then voice specific.

Parameters

  1. Wave
  2. Rate, Sync and Phase
  3. PWM
  4. Step Rate and Step Sync
  5. Glide

Wave

Wave lets you select the wave form of the LFO (low frequency oscillator) by clicking into the wave display. The following wave forms are available:

  • Triangle
  • Sine
  • |Sine|
  • Square
  • Random
  • Wave 1..5

[Parameters]

Rate, Sync and Phase

Rate sets the LFO's frequency which can also be synchronized to the host's timing via the Sync parameter. The Phase parameter is only useful in combination with host synchronization and lets you control the starting point of the wave form synchronized to the beat.

[Parameters]

PWM

PWM adds even more control to the wave form by applying pulse width modulation.

[Parameters]

Step Rate and Step Sync

The LFO signal is routed through a stepper which acts like a sample & hold device. This yields a neat rythmic effect. Step Rate sets the sample frequency. With Step Sync the sample times can be synchronized to the host's timing.

[Parameters]

Glide

The glider is somehow the opposite of the stepper because it smoothens the signal which yields nice effects e.g. in combination with the random wave mode. Glide specifies the time to adapt to the new value.
