Rotary Control Modes - OverTone DSP Plug-ins V3

 
PTC-2A
Introduction
 
The OverTone DSP V3 Plug-ins added several feature enhancements and improvements. One of the most significant, and often overlooked, being the introduction of three new physically modelled control modes, which determine how the user interface responds to mouse movement.
 
  • Circular.
  • Relative Circular [default].
  • Linear.
In host applications which support control mode selection, this can be configured in the application preferences. In those which do not, the plug-ins will default to Relative Circular mode. This article details each of the available modes and how they respond to user input.
Relative Circular Mode
 
Relative Circular mode responds to angular movement of the mouse pointer. Clicking on the control to select it, as normal, and then dragging in an arc, clockwise or anticlockwise increases or decreases the setting.
 
The control moves relative to its original position, while varying the mouse pointer distance from the control's center increases or decreases the sensitivity to mouse movement.
 
Using the scroll-wheel with the mouse pointer positioned over the control will step up or down in the usual way, while it can be quickly returned to its default setting by double clicking in the center.
 
Relative Circular mode is the default setting in the absence of configuration by the host application.

Circular Mode
 
Circular mode responds to angular movement of the mouse pointer in a similar way to relative circular, but with an important difference. Clicking on the control to select it immediately moves the control to the current angular mouse pointer position.
 
Dragging in an arc clockwise or anticlockwise increases or decreases the setting as previously, while varying the mouse pointer distance from the control's center increases or decreases the sensitivity to mouse movement as before.
 
Using the scroll-wheel with the mouse pointer positioned over the control will step up or down in the usual way, while it can be quickly returned to its default setting by double clicking in the center.

Linear Mode
 
Linear mode responds to vertical movement of the mouse pointer. Clicking on the control to select, as normal, and then dragging up or down increases or decreases the setting.
 
Using the scroll-wheel with the mouse pointer positioned over the control will step up or down in the usual way, while it can be quickly returned to its default setting by double clicking in the center.

Physical Modelling
 
Rotary control modes sometimes get a reputation for being awkward to use, or over sensitive to mouse pointer movement - a control may jump to extreme settings or become excessively 'twitchy'. Often this can be an aspect of implementation rather than a flaw in the concept.
 
In many ways, the rotary control modes offer distinct advantages over linear equivalents. For example, varying the mouse pointer distance from the control's center continuously varies the adjustment sensitivity in an intuitive manner. Just as with real hardware, where a large physical control knob allows much finer control than a smaller one.
 
Importantly, while moving the mouse pointer closer to the center increases adjustment sensitivity, in the OverTone V3 Plug-ins this is balanced by modelling the increasing physical 'difficulty' of rotating a real control in this way, due to the reduction in mechanical advantage. This ensures that the controls never become too sensitive to mouse movement and will not become twitchy of unpredictable.
