The acoustic model, inverse pitch solver, hole editing, drag behavior, units, and multiple fingering views are active. Profile and scale editors remain for later milestones.

Flute view

        
Click a hole to open or close it. Drag a hole to change its position. Enable pitch-preserving drag to adjust its diameter while maintaining the active view's frequency.

        
Pitch solver

        
Enter a frequency or legacy note name such as A3 or C#4, select the geometric variable, then solve for the target.

        
Views and scales

        
Fingering views share flute geometry but keep independent hole states and registers. The scale editor stores up to 30 printable fingerings.

        
Files

        
Open and save the original INI-style .flu files. The browser warns before discarding unsaved changes.

        
Keyboard shortcuts

        
Use Ctrl+O to open, Ctrl+S to save, Ctrl+I to insert a hole, Ctrl+R to remove the active hole, Ctrl+F to add a fingering view, and F1 for Help.

        
Profile

        
The profile editor supports three interior and exterior segments using linear, parabolic, exponential, logarithmic, or inverse curves.
