I do not agree with you dear Mark. Staccato or spiccato notes need not be played at a higher volume than legato notes. I have been using CC#11 for some 25 years now, mainly for fade-outs on long notes. For individual notes, long or short, velocity is traditionally been used (e.g. Vienna samples) to control volume, which UNFORTUNATELY is not used by SA, except for some short notes. Instead, SA controls the note volumes by CC#1, CC# 7, as well as CC#11 and velocity for some samples, i.e. four kinds of control, all doing the same job, possibly conflicting at times with each other. To my mind, you only need velocity and expression to do the volume control job. Please visit my page in Youtube to verify what I am saying: https://www.youtube.com/channel/UCy-AP1lqlQ-hKDY8ylRMk-Q/videos
BTW I have bought the BBC SO Discover for a certain price. It was not a free D/L.
In any event, thanks for your attention dear Mark
