4 Parameters

This section can be used as a reference for the different controls appearing on the Ultra Analog

VA graphical interface. We begin by describing the behavior of the different types of controls

appearing on the interface and then describe the parameters of each module of the synthesizer.

4.1 General Functioning of the Interface

4.1.1 Knobs

The synthesizer parameters are adjusted using controls such as knobs, switches and numerical

displays. A speciﬁc control is selected by clicking on it. A coarse adjustment is obtained by click-

holding the parameter and moving the mouse, or the ﬁnger on a track pad, either upwards and

downwards or leftwards and rightwards. The value of the parameter replaces its label while it is

being adjusted.

Fine adjustment of a control is obtained by holding down a modiﬁer key of the computer

keyboard (Shift, Ctrl, Command or Alt key) while adjusting the parameter.

Double clicking on a knob brings it back to its default value when available.

4.1.2 Switches

Switches are turned on or off by clicking on them. They are used to activate or deactivate modules

and the sync feature of some parameters.

4.1.3 Drop-down Menus

Clicking on a display with a small down-pointing triangle reveals a drop-down menu with a set of

possible settings for the control. Adjustment of the control is obtained by clicking on a selection.

4.1.4 Modulation Signals

Different parameters can be modulated by the signal from different sources including the MIDI

keyboard, envelope generators and the LFO modules. Modulation signals are controlled with

small gain knobs located on the left of the corresponding modulated parameters.

The Key modulation knobs are used to modulate a parameter depending on the note played on

the keyboard. When in its center position, the value of the corresponding parameter is equal across

the whole range of the keyboard. Turning the knob to the left increases the value of the parameter

for low notes while decreasing its value for high notes. The variations are applied relative to the

middle C (C3, MIDI note 60) whose value is always that corresponding to the settings of the actual
