Virtual Fundamental Generator Plug-in

How to get there

Select a sequence of chords in one staff with the Selection Tool l. All chords must be in layer 1, voice 1. From the Plug-ins menu, choose Scoring and Arranging, Composer’s Assistant, and then Virtual Fundamental Generator.

What it does

The Virtual Fundamental Generator plug-in creates a new staff below the selected staff. Below each chord of the selection, it displays one bass note, which is the virtual fundamental.

The virtual fundamental algorithm is a psycho-acoustical algorithm that finds a bass note (a fundamental) for which all the note of the chords may appear as harmonic partials. When adding this bass note to the chord, it makes it sound better, less tense and more homogeneous. The virtual fundamental may be thought of as a “root” for the chord.

• Specify Lowest Pitch · Listen. The number in the Specify Lowest Pitch field represents the lowest MIDI note that will be created by the plug-in. You can either use the spin controls to change the value, or click the Listen button followed by playing a note on your MIDI device to specify the pitch. Middle C, or C4 is represented as MIDI note 60.
• Allow Octave Displacement. Checking Allow Octave Displacement means that if the virtual fundamental is below the ‘lowest pitch’ threshold given in the dialog, the plug-in will compute the closest octave of the fundamental that is above the threshold. Without checking this, any virtual fundamental that is lower than the specified lowest pitch will be ignored.
• More Info · Cancel · OK. Click More Info for a reminder of what input this plug-in requires and a brief summary of what the plug-in does. Click Cancel to dismiss the dialog box without making any changes, or Click OK to make the selected changes.
