(Only Available in the full version of Diamond Strings)
Instead of going back and forth choosing half step or whole step trills while you play, TVEC 3 can automatically figure out which trill to use based on the key signature you have selected. There are 37 key signature possibilities - 12 major, 12 natural minor, 12 harmonic minor and 1 "no key". What is especially nice about this feature is that when you play a chord that requires 2 different kinds of trills, TVEC 3 knows which one to use for each note.

Using TrillsLive®
Whenever you select a half step or whole step trill articulation, the trills are governed by the key signature you have set. To set this, choose "Set Key Signature for Trills" from the "SETTINGS" menu.

The TrillKey knob will appear. With this knob, you can set the key signature. You will see the key signature you've selected in a small display window just above the knob. (See the yellow arrow in the diagram below) When you are finished, click "DONE_SETTINGS".
