Changing Duration tuplets - AaronDavidNewman/Smoosic GitHub Wiki

You can create tuplets from the keyboard by typing Ctrl+3, Ctrl+5 or Ctrl+7 for triplets, quintuplets, and septuplets, respectively. Individual notes in a tuplet can be doubled and halved with the duration keys - (minus) and = (equals), just like non-tuplets. You 'untupletify' a tuplet by Ctrl+0.
