Restricting the Key

In Dubler 2 you are always in some form of key restriction. That means that Dubler will only output notes that are in that key.

You can see the current key restriction on the play tab - and make a quick change to another key by using the drop downs for root note and scale. As a default a new profile will have Auto Key Detect on. 
Auto Key Detect will detect the notes you are singing and automatically assign you to the closest matching full scale.

Both the piano roll and the pitch wheel illustrate which notes are in the key restriction.

The pitch wheel is split into 12 segments, one for each note in the chromatic scale - A, Bb, B, C C# etc. Dubler will only show notes on the pitch wheel that are in the current key restriction

So for example when in a C major and only the notes in the C Major scale are shown on the pitch wheel. If you sing a note that isn’t in this key, such as a C#, Dubler will instead output the nearest in-key note to your input pitch.

In any given key restriction you can limit the notes further by clicking on an active note on the piano roll or pitch wheel to deselect it.

If you want to start adding in notes that aren't in the key - then that would actually mean changing key entirely which you can do over on the Key tab
The Key tab allows you to set the current key restriction by either selecting desired notes on the pitch wheel, or singing in notes.

To find a Key Restriction by singing, select Key Detect and sing your melody into the mic. 
It will display the notes you’ve sung on the pitch wheel, and on the right suggest a list of keys based on those selected notes. If you’re unhappy with the notes you’ve sang in, you can hit the eraser button to clear the pitch wheel and start again

You can also click any note on or off on the pitch wheel and the listed of suggest keys will automatically update.

The key restrictions are listed in order of how well they fit your selection, and you can choose between either the Subset of a key or the full key. Clicking on a full key will include all the notes in that suggested scale, whilst the subset will keep the restriction limited to only the notes you have selected.
You can hear a preview of the scale by clicking the play button next to each.

Simple mode will show a list of the most commonly used scales. Switching to advanced will show more complex scales that your notes may fit into.

To update the pitch wheel, select 'Apply to Current Key' by hovering over your chosen scale.
