Hello Colin,
the Pro Edition will offer a new perf-leg_f set.
Here the intervall steps are played on different strings, so the sound of this instrument will be brighter.
Generally we didn't plan to produce more velocity variations for the string ensembles.
For the EXS version we layered the piano and forte version using crossfade layers, which works really great. When Gigastudio 3.0 is available we'll support of course this new mappings possibilities.
Generally we'll concentrate in our developement on more different playingstyles.
The upcoming soloviolin will give you a little overview about these possibilities. Here we produced performance detaches, and performance spiccato. It's the same concept as the legati, only different articulations.
For the Violin ensemble we also recorded performance tremoli - intervall changes during tremolo playing; and performance glissandi.
Also new are the performance-legati with sordino.
best wishes
Herb
