The SMO also has pink and white noise as possible selections for its ‘waveshape’. Using noise obviously negates the frequency controls, and in fact, only the SMO Level modulation is relevant.

Vibrato LFO (V-LFO)

The Vibrato LFO is dedicated to the vibrato effect and has its own control area on Solaris’ Main page. The

Vibrato LFO in Solaris is a multimode LFO, with most of the parameters that come with the multimode LFO added: Delayed start (DelS), Fade In control, Retrig and Phase options, and MIDI clockability.

The SMO has the following controls over the amplitude:

Delay Start, Fade In, and Fade Out. These parameters are calculated from each note-on ( Gate) event.

Fade Out values must be greater than 0.00 – at zero, the Fade

Out circuit is ignored, and the SMO stays at full level.

When Retrigger is ‘On’, the SMO will start its modulation from the same point in the waveshape every time a gate signal is received. The Phase control allows you to set exactly where the progression of the SMO’s waveshape will start (only functional when Retrigger is on).

Bias provides a list with two choices – Offset, or Rectifi ed. Offset reduces the SMO’s output and shifts it into positive values only; Recitifed does not reduce or shift the signal, but only allows the positive portion of the waveshape to pass. (This is perhaps more useful when using the SMO as an audio rate modulator.)

You will notice the Frequency parameter changes its controls, depending on the KeyTrack switch. Without

KeyTrack, the display gives a normal frequency reading in Hertz. When the KeyTrack is switched ON, this display changes to a Coarse and Fine tuning, to refl ect the use of the SMO as an audio rate oscillator. When switching to MIDI Clock Sync, the Frequency and tuning of the SMO is overridden by the incoming MIDI signal, disabling and removing the other frequency displays.

MIDI Clock Sync switches the frequency control to a popup table of note values/divisions. See the MIDI

Implementation section for a description of the values.

Quantisation takes the incoming signal from the SMO and divides it into discreet amounts, so that the continuous analog signal is ‘stepped’, providing a series of pitches or notes. The greater the Range setting, the wider the quantisation occurs; the Steps setting controls how many semi-tone intervals are to be calculated
