3. Parameter Reference
3.7. LFO1/2
A LFO generates a LFO (Low Frequency Oscillator) signal for the oscillators, the filter and the amplifier as a modulation source. Exciton has two LFO's (LFO1 and LFO2) in the LFO section and each LFO's have the same function.
3.7.1. Wave
Specifies the LFO waveform.
It selects the waveform from sine, triangle, sawtooth, square, sample&hold and random.Exciton does not have a negated sawtooth wave for LFO. But you can set the modulation depth the negative direction.
3.7.2. MONO
Switches the polyphonic/monophonic mode of the LFO.
For the polyphonic mode (MONO off), each voices have the individual LFO's. For the monophonic mode (MONO on), single LFO is used for every voices.
Using with the polyphonic mode, voices have each LFO units and their phases are randomized within voices. To the contrary, all voices use the same LFO for the monophonic mode. The difference is important for some cases as follows.
If you use the unison mode and use a LFO for detune, you ought to use it with polyphonic mode. The each LFO's change signals randomly and detunes the oscillators within voices.
On the other hand, if you use a LFO with the sample&hold waveform for a sound sequence, you should use with monophonic mode. Modulations for all the voices are synchronized with the monophonic mode and all voices are changed at the same timing.
3.7.3. Speed
Sets the LFO speed.
This sets LFO speed as a frequency. Turning the knob to the left slows the frequency and turning to the right gets fast.
