52 Parameters

The Rate knob sets the frequency of the vibrato effect from 0.3 Hz to 10 Hz.

The Amount knob sets the depth of the effect, or in other words the amplitude of

the frequency variations. In its leftmost position, there is no vibrato and turning

the knob clockwise increases the amount of pitch variation. The MW gain knob

is used to determine the effect of the keyboard modulation wheel on the depth

of the vibrato. When this knob is fully turned to the left, the modulation wheel

has no effect but as it is turned clockwise the depth of the vibrato increases

when the modulation wheel is used. The increase is always relative to the position of the Amount

knob and becomes greater as the MW knob is turned clockwise.

The vibrato can be adjusted not to start at the beginning of a note but with a little lag. This lag,

in seconds, is set by the Delay knob. The Fade knob allows you to set the amount of time taken by

the amplitude of the vibrato effect to grow from zero to the amount set by the Amount knob.

4.4.6 The Arpeggiator Module

The Arpeggiator module allows one to play sequentially all the notes

that are played on the keyboard. In other words, arpeggios are played

rather than chords. The modules allows one to produce a wide range of

arpeggios and rhythmic patterns and to sync the effects to the tempo of an

external sequencer.

Arpeggio Patterns

The arpeggio pattern is set by the combination of the value of the Range,

Span and Order controls. The Range control is used to select the number of octaves across which

the pattern is repeated. When the range is set to 0, there is no transposition and only the notes

currently depressed are played. If set to a value between 1 and 4 (its maximum value), the notes

played are transposed and played sequentially, over a range of one or more octaves depending on

the value of the Range parameter. The direction of the transposition is set with the Span drop-down

menu. This parameter can be adjusted to Low for downwards transposition, to High for upwards

transposition or wide for transposing both upwards and downwards. Finally, the Order control sets

the order in which the notes are played, therefore determining the arpeggio pattern. When set to

Forward, the notes are played from the lowest to the highest. When set to Backward the notes are

played from the highest to the lowest. In the two last modes, Rock and Roll exclusive and Rock

and Roll inclusive, the notes are played forward from the lowest to the highest and then backward

from the highest down to the lowest. When using the RnR exclusive mode, the highest and the

lowest notes are not repeated when switching direction but in RnR inclusive mode these notes are

repeated. Finally, in Chord mode, all the notes are played at once.
