AudioTheory Piano Keys 2.0 is the biggest update yet. This new versions adds in many new features and improvements including faster tools for swapping chords, a new light theme, and a colour wheel for selecting the application colours.

Quick Select Chord Types

Previously, loading a new chord required finding and selecting it within the chord library. It's still possible to do this, but now there's also a dropdown that you can use to swap chord type much quicker. If you already know what cord you're after – this is a simpler and faster way to load it.

Light theme

A brand-new look is here in the form of the light theme. This mode is perfect if you want to print out a physical copy of your diagrams.

Relative note display updates

A few changes have been made to improve how the application handles relative note name formats (Degrees, Roman numerals and movable do). These now display relative to the last selected scale, rather than the current scale. This has the effect of allowing you to subtract notes from the scale and still see the relative intervals for what's left. E.g. if you were to start out with C major you could then remove D, F, A and B to be left with C, E and G, which would be labelled as 1, 3 and 5 respectively. To further support this, auto scale matching now only checks the current scale set group, as well as and the regular major and minor scales. This prevents accidentally swapping to the pentatonic scale of another key (e.g. G A B D E can be viewed as a subsection of C major, and won't automatically swap to G major pentatonic in this situation).

And the rest...

There's a whole load of bug fixes and other things that have made it into this update too:

• Revised application colours and fonts for a modern new look
• Real-Time Scale Highlighting now only updates when the pressed note is enabled in the note selector (i.e. it doesn't update if the key you're pressing is greyed out)
• The settings now include an option to offset the octave at which piano chords are played at/ highlighted
• The settings now include an option to turn off input highlighting across the piano chord set in the main application view

• You can now click on the scale name in the bottom left to swap between the major and relative minor scales
• 'Interval' label corrected to 'Degrees'
• Splash screen has been removed
