When using Ultra Analog VA-3 in plugin mode, the Tap Tempo pad is replaced by
a Sync To Host switch. In its on position, the rate is synchronized with that of the host
sequencer. When switched
off
, the tempo is determined by the value of the
Rate
knob.
5.2.2 The Keyboard Module
The Keyboard module controls how the synthesizer voices respond to the events
coming from an external MIDI keyboard or from a MIDI sequencer.
The keyboard can be monophonic, allowing one to play only one note at a time,
or polyphonic, allowing one the play chords. This behavior is adjusted using the Poly
button. The keyboard is in polyphonic mode when this button is switched on .
The Tune control is used to transpose the frequency of the keyboard. This control is composed
of two numbers separated by a dot. The first number indicates a value in semi-tones while the
second one indicates a value in cents (one hundredth of a semi- tone). The amount of transposition
can be adjusted by click-dragging upward or downward on the semi-tone and cent controls. Double
clicking on these controls brings back their value to zero. When the value of the Tune parameters
is set to 0.00, the frequency of notes are calculated relative to A4 with a frequency of 440Hz.
5.2.3 The Unison Module
The unison mode allows one to stack voices, in other words, play two or four voices
for each note played on the keyboard. This mode creates the impression that several
instruments are playing the same note together, adding depth to the sound. It is switched
on by clicking on the LED located in the upper right corner of the module.
Each voice can be slightly detuned relatively to the others by using the Detune knob.
Turning this knob clockwise increases the amplitude of the error. Furthermore, voices
can be desynchronized by adding a small time lag between their triggering with the
Delay
knob.
There is no delay when the knob is in its leftmost position and it increases (units in ms) as it is
turned clockwise.
5.2.4 The Glide Module
The Glide module is used to make the pitch slide between notes rather than chang-
ing immediately from note to note. The Time knob sets the amount of time necessary for
the pitch to slide over one octave. The Mode drop-down menu enables one to choose be-
tween the Constant or Proportional mode. When in Constant mode, the time necessary
for the pitch to slide from one note to another is always the same regardless of the inter-
val between the notes. When set to proportional, the slide time becomes proportional to
the width of the interval between the two notes.
