You guys are thinking too much. I understand the wish to save time, but you've been using VSL libraries successfully for many years (I suspect), with these 'transition' faults, without batting an eye, until it became a forum topic. If it was a real issue it would have been addressed a long time ago by VSL. It's an affectation, not an issue. No one but those who listen on a microscopic level hear this, I'm sure. Who do you want to please? The people who listen, or the people who play? If listeners, it's a non-issue; if players, well, that's your ego talking. If yourself, learn to dumb it down like has always been the case.
I am speaking grossly of course, maybe some patches need reworking, but in general, no one hears these slight differences, except the musician who wrote the piece; so move on and think in 8 bit for your listeners.
