Hi, 

I´d check the Polyphonic Legato Video for VI PRO. You can change the Start Offset time of the legatos in the "Advanced Tab" of the Advanced View, this way you also get different legato transitions (by shortening the transition). Starts around 2:10

Best, 

Paul

Here's a demo of the results when I follow that recommendation. Two phrases: the first is how the patch plays by default in VI Pro, and the second is how it plays after I've changed the Start Offset time:

The patch for both phrases is:

/B -  Woodwind patches/46 Clarinets - a3/98 RESOURCES/03 Perf Speed variation/01 KL-3_perf-leg_sustain

After watching the video, I didn't understand the difference between Start Offset and Start Offset Attack, so I set both of them to the values shown in the video.

This is a leg_sustain patch, so there's looping. When I pay attention to the pattern of the looping (testing on F-Sharp-3 with a low note-on velocity, after a legato transition from G3), I hear a cycle of 3 samples, each a crescendo. Since there is grafting of samples here, I wonder why VSL doesn't give us an option to adjust the relative volume of the transition samples.

it would be good to post some examples of a "too loud" transition, so that we can all agree as to what we are hearing.

Here are the files I posted previously, now hosted in Dropbox since Google-Drive wasn't working for multiple people.

Here are the clarinets at default, as described earlier:

and here are the clarinets after adjusting them according to the recommended video, as also described previously (Phrase #1: at default. Phrase #2: adjusted.):

I also have the same problem being described with bumpy legatos.  This is especially true with the older vsl libraries and/or patches that have fewer legato velocity layers than sustain velocity layers.

I think Dave may have been suggesting this earlier, and I would agree that a nice additional option to start offset would be a volume envelope approach similar to the envelope for time stretching in VIPRO.  The envelope, of course, would need to apply only to the legato transition layer.

Set offset functions are very useful for shaping legato transitions, but somtimes you will have to combine these with Atk and Rel faders as well (different values for different transitions). And don't forget the "global" patch parameters in the Envelope Area.
