LinPlug Spectral - Manual (Page 12)

User Interface / Controls
On Mac the interface supports both traditional and Retina displays
automatically. On PC you have the possibility to change the User Interface
size with the menu on the very top left. Available resolutions are M=100%,
L=150% and XL=200%. The selected size is stored permanently and used
whenever you open up a new instance of Spectral.
The controls (dials) on the user interface are operated in a linear manner,
so move your mouse up/down to modify a control.
Holding down the ALT key while clicking on a control changes the selected
control's value a minimum step upwards (when clicking in the upper half of
the control) or a minimum step downwards (when clicking in the lower half
of the control).
Holding down the CTRL key (Windows) or COMMAND key (Mac) while
clicking on a control sets the control to its default value (e.g. for Volume
controls it sets the control's value to 0 dB).
Holding down the SHIFT key while changing a control's value enables finer
control values to be set.
Double clicking one on a Modulation Matrix Depth parameter sets the value
to 0.00. Double clicking in the same parameter a second time resets it to its
previous value. This is handy for quickly disabling (and re-enabling) one or
multiple modulations.
The Oscillator and Effects selector buttons have a double function: when
you right click them this changes the state of the Oscillator or Effect from
On to Off and back. This way you can quickly disable certain Oscillators
and Effects and enable them again.
All Controls can be controlled using external MIDI messages. To do this you
need to use the MIDI-Learn which is described in detail later in this manual.
