The attachment shows the word "day" with a slur. The slur in green is satisfactory (usually!). If this slur is de-activated (red) or removed, I hear an explosive click at the start of the word.

Tony, did you set yourself the "slur delay" to 110?

Yes, I set the delay at 110/256. The triplet note period is 1/3 x 512 (=170), but maybe this is too short to effectively use a slur. I have tried changing the note, delay, pressure time (appui), attack & decay (montée & descente) and the singer's processing deferment (avant/pendant), but everything seems so variable and unpredictable.

OK Tony... Then, if you return to "Don't play it", you should revert the "slur delay" to zero. <opinion> These "play" parameters actually don't apply to true slurs, but to glissando's, however sometimes referred to as "Italian Slur". (in popular French it's often called "déguelando") Playing a slur should simply involve setting the pressure ratio to 100 to all notes in the slur, except the last one. </opinion>

The effect you are noticing is related to how the voice is defined in VS. If you adjust the attack to be more on pitch, that should take care of things (and you might want to save the modified voice for future use). I greatly slowed down the tempo, which made it obvious that the standard tenor is approaching the upper note from below (at least a quarter-tone flat) and scooping up to the proper pitch--before descending again, when the slur is sung. The "explosive" attack you notice is an artefact of singing this upward scoop at the tempo you set. I'm not sure why the sung slur makes the singer approach the pitch more accurately, but it's probably something to do with the slur algorithm's need to make sure that the starting pitch is heard before starting the downward scoop. This scoop up to the pitch is typical of less-careful singers in real life, and it is therefore the default in VS voices. When I created the choir voices that I use, I specified accurate pitches for the attacks, and then saved them for re-use. In real life, the director generally has to tell the singers to sing sharp, and that gets them to hit the correct pitch without the upward scoop.
