When you are in the PRV and you click on a MIDI note you can hear the sound. For example if the note you grab triggers the snare drum and you then move it up or down it will trigger different drum sounds while auditioning them at the same time. However I've assigned keyboard shortcuts in order to nudge selected notes up or down. The problem is the notes are no longer sounded when I use a keyboard shortcut. This is something I'm used to doing in Samplitude - it's called "Play Clicked notes". This feature is also available in Cubase and Studio One and Logic. Please consider implementing this in Sonar.

+1. Also, currently we have to use CAL scripts to nudge up or down an octave, or anything more than a semitone. This needs to be implemented in the actual nudging functions, as well as hearing the sound of course.
