@goldsmith,
Thank you for your comment.
The reason why I posted this is to figure out where is SSP in the VSL products line.
Is it a standalone product which will be completed later to achieve fast attack in Long/legato samples or should we use the SS1 sounds to achieve this ?
It seems to me that SSP has a complete new approach in term of velocities layers.
Most of of samples have 2 velocities layers instead of 8-9 in SS1 which could explain why the variation of the velocity XF control CC1 has less impact than in SS1.
Furthermore, the names of samples have changed from Cantabile, soft to very soft or pianissimo, or from slur to agile...
It is a bit confusing without a few explanations about the purposes of each sample group.
Besides of that, I found the sounds amazing and beautiful for soft music passages.
