SPECTRALIS 2

3.3.5 The LFO section of the analog-synth

Since firmware version 93k the Spectralis Analog-Synth has a very extensive

LFO section. No less than 10 LFOs in the Spectralis in the Analog section

alone are at your disposal. 4 of these LFO's have been designated as Master-

LFO's. These LFO's have some additional features compared to the other 6

LFO's.

1.) The master-LFO's have a central edit section.

2.) The 3 main parameters LFO-wave, LFO-rate and LFO-depth on these

master-LFO's can be adjusted using just simultaneously for all LFO's using

just one Encoder.

3.) The master-LFO's don't have fixed routing. You can select in the edit-sections

of the oscillators and filters which parameters you want to be affected.

4.) The master-LFO's have envelope curves for control over modulation depths.

5.) The master-LFO's have a depth parameter, which makes it possible to change

modulation levels for multiple parameters simultaneously.

The master-LFO's have three controls on the left side of the synthesizer edit

section.

Encoder 1 allows the selection of the LFO waveforms, encoder 2 is used for

adjusting the master-LFO's modulation levels and encoder 3 controls the

modulation rate of the four master-LFO's. The encoders on the control panel

always simultaneously affect all 4 master-LFO's. When you are pushing the

one of the encoders, the corresponding parameters for all 4 master-LFO's will

be shown in the display.

[LFO-rate]

When pushing the encoder button the following display message shows:

Master LFO Rate Menu

^MLFO1:0 ^MLFO2:0 ^MLFO3:0 ^MLFO4:0

You now can either change the speed of each LFO individually using the

4 controls under the display or change the speed of all LFOs

simultaneously using the encoder [Mod Rate]. If you are adjusting all

four parameters individually, the [Mod-Rate]-Encoder will adjust the

values of the individual LFOs' in additive fashion.

[LFO Mod Depth]

This Encoder changes the modulation depth (intensity) of the 4 Master-

LFO's. The modulation value of the Spectralis uses exponential scaling.

Close to the Zero setting you can effect subtle sound changes. The furt-

her you move away from zero, the more obvious the modulation change

increases will become with each step. At the upper end of the scale rat-

her dramatic modulations will take place. The modulation range is from

-127 to +127. Using negative values the modulation will affect the

parameter values in opposite direction.. When using the [Mod-
